Lowest cost and easiest way to eliminate green hair, bubble, turf and slime algae from your aquarium (hopefully permanently).

This new test version of the algae scrubber is much easier to build than the waterfall version (the Mega Powerful one), and is perfect for nano's. This new scrubber has never been posted before May 2012. It works in both freshwater and saltwater.

If you are like most aquatic hobbyists, nuisance algae is an ongoing problem. You try to feed your livestock, and the next thing you know, you get algae. You've already tried many fixes; some work but are expensive; some kind of work but you're not sure; and some just don't work at all.

Think about what is happening: Your aquarium is accumulating nutrients (nitrate and phosphate) because of the food you feed. Algae eat nitrate and phosphate to grow, so the algae are having a great time growing in your water because they are eating all your nutrients! What to do?

Well think about this: In order to grow, algae must be provided with nitrate and phosphate. So why can't you just use the algae to consume all the nitrate and phosphate? The answer: You can! How? With a simple device you build called an Upflow Algae Scrubber. It's simple, cheap, and you can make a small one in just a few minutes with parts you probably already have. I'll be posting more complex versions later, but here are some pics of the most basic design that you can use for testing:

(will be updated periodically)

An "algae scrubber" is a simple filter that actually grows algae in the filter, so that the algae do not grow in other parts of your aquarium. Simply put, the conditions for algae growth inside the filter are better than the conditions in the rest of your aquarium; thus the algae grow in the filter instead of your aquarium, and then you just remove the algae from the filter and throw the algae away. But in order for the algae to grow in the filter, the algae need to consume nitrate and phosphate; so guess where the nitrate and phosphate come from? Your water!

If you stop and think about it, algae always grow in certain spots, and not in others. This is because some of the three growing conditions (light, flow, nutrients) are better in some parts of your water than they are in others. An "upflow algae scrubber" simply optimizes these conditions, and does so at a place where the algae can be easily removed and thrown away. And once the nitrate and phosphate have been removed from your water, all other nuisance algae such as green hair, bubble, turf and slime, will have a hard time staying alive.

So where have these filters been all this time, and why haven't you heard of them if they work so well? Well the original waterfall version (the Mega Powerful thread posted in August 2008) was hard to build, and was not really for sale anywhere; so unless you liked to build things from scratch, you had no choice but to buy some other kind of filter. All the filter really needed to do was to create good growing conditions (light, flow, nutrients) for the algae, by flowing the water across a piece of rough material, so that the algae would grow on the material instead of somewhere else in the aquarium. The waterfall algae scrubber did grow lots of algae in the filter, and it removed lots of algae from aquariums: Over 1,000 people built their own waterfall algae scrubbers, and reported their results on various forums during a 4 year period; almost all of them wiped out their nuisance algae within 8 weeks, and many did so in 4 weeks. And on other forums that I never posted on, an estimated 10,000 people built their own waterfall algae scrubbers with similar results.

A little over a year ago in April 2011, another idea came along: Instead of letting the water flow down a screen like a waterfall, how about you let the water flow up the screen using air bubbles? Why? Because as good as waterfall algae scrubbers are, they still need a place for the water to drain "down" to. This means that you need to have a sump below the aquarium, or you need to have the scrubber up above the aquarium. This is not easy, and is very difficult for a nano aquarium which usually has no sump below it, and no room above it. Also, the waterfall version requires it to be out of the water (in the air), which takes up extra space. The new "upflow" version, however, can be placed inside the aquarium, so that it takes up no extra space at all, and it needs no external plumbing or water pumps at all. Only air bubbles.

The Upflow Algae Scrubber (UAS) provides the best growing conditions for algae in your tank: Air bubbles provide rapid turbulent flow; Strong lighting provides the light; and the nutrients that are already in your water provide the nitrate and phosphate. All that's needed is a place for the algae to attach to, and that is provided by the roughed-up plastic screen. Thus the algae start growing on the screen because the flow and lighting are stronger there than they are in the rest of your aquarium; nitrate and phosphate are consumed in the process. This causes algae to start disappearing from your aquarium and start re-appearing on the scrubber screen, so that you can throw the algae away every week or two.

The most basic way to set up an Upflow Algae Scrubber, especially in small aquariums, is just to put some air bubbles beneath a vertical screen. If inside an aquarium, you just put a light on the outside of the glass, so that it shines inside to the screen. And if you want better performance (which means better filtering), just add a reflector to give the screen some light on both sides. The screen is best made with 7-mesh cross stitch plastic canvas that you get at sewing or craft stores, or online. Also, don't forget to rough up the screen with a sharp object like a hole saw; the screen should be so rough that the screen holes are almost filled in with all the little pieces of plastic that you roughed up.

One thing to remember is that an Upflow Algae Scrubber (or any algae scrubber) will not cause more algae to grow in your aquarium. Instead, the algae will disappear from your aquarium, and will start to grow on the scrubber screen instead. You then just remove the screen and scrape the algae off. And here's a surprise: Watch out for your fish or snails eating your filter! There's nothing tastier than live green algae, so your fish or snails may keep your screen from getting very thick. The simple solution is to just put some mesh or netting around it.

There are a couple of requirements that have been learned since August 2008 which will get you started quicker. The size of the Upflow Algae Scrubber that is needed is based on how much you feed, and not how much water you have, because the nutrients that cause algae to grow come from the food you feed. The following updated picture has size guidelines:

Това не изключва наличието на водорасли и на други места, просто добива още на изолирано място. Нещо не ми харесва тази идея.
Разни мои АКВАРИУМИ 


това е просто като малък водораслов филтър.
не знам дали този размер може да усвои чак толкова много.
аз лично смятах да направя една аква на слънчево място в къщи с вграден съмп отзад на разтояние 2см. примерно.
водата първо да минава от задната страна (осветена от слънцето и мрежа м/у задното стъкло и съмпа), да влиза в него и да излиза вече отпред.

Стоян Михов

То това е повече за морски аквариуми, ако искаш я прехвърли темата в морското оборудване, там вече имаме теми за този филтър, но сега Santa Monica е измислил нещо "ново" и го пръска из морските форуми из целия свят.  Пък аз там ще я поредкатирам и ще я приведа в по-български вид.

El sol funciona bien, pero necesitas por lo menos 6 horas de luz solar intensa.


Entonces tengo que cambiar el epartamento antes de hacer lo  :-D, porque en este 6 horas de luz directa me parece inposible

Тогава може би можете да използвате щипка-КФЛ, когато има не слънчева светлина.

Some success stories of people using waterfall algae scrubbers on different sites:

Aydee on the scrubber site: "I'm going to call this a success. My nitrates had been sitting steady at about 10 or so for over a year. For it to drop to undetectable in 2 weeks.. THAT is impressive. I have got my skimmer running still, but once my ATS is running, I'll turn off the skimmer (not remove.. Yet....) If situation remains excellent as the trend currently is, I'll remove the skimmer. However, I came into ATS thinking "It can't hurt, as I'll keep my skimmer running" and now I'm thinking "WOAH! They're right!".
Obviously, the proof will be in 2 years time, ATS sans skimmer.. But.. So far, the numbers are fantastic."

Robert_Patterso on the RC site: "Best thing I have ever put on any of my tanks in over 25 years of being in the hobby"

Pskelton on the RC site: "I personally have not done a water change in 6 months ever since I implemented my scrubber. long story short my tank was a mess, kid dumped container of food in tank. I got a snow flake eel that dug up my sand bed and I was running a very under powered cheep skimmer. This lead to my nitrates peeking at 160. I did water changes for a while but the nitrate just keep coming back up to 160. The water changes were getting expensive and I was about to give up when I tried the scrubber. Within a few weeks nitrate dropped to 60 and slowly came down from there. As of my test last week I am finally at 0 nitrate and I haven't done a water change in six months. The protean skimmer has been removed and my tank is healthier than ever. I am just waiting for the algae on my rocks to finish dieing off."

Murph on the scrubber site: "my ATS is coming along fine. I think I spent about 30 bucks making it. When I compare that to the thousand or more I have spent on skimmers over the past ten years or so that made little to no difference when it came to nuisance algae in the display I want to pull my hair out. My ATS has out done them all in a matter of a few months."

Spotter on the RC site: "Nitrate Day 1: 5ppm, Week 1: 0ppm, Week 2: 0ppm. P04 Day 1: .035,
Week 1: .015, Week 2: .0092  I am liking this very much."

JohnnyB_in_SD on the RC site: "I feed about 6-7 cubes a day on a 100gl tank, and 10-12 cubes two days a week when I do the nems & corals too. N&P have been undetectable since I started using ATS, which is a mickey mouse rubber maid tub version. Since I am always looking for the easiest way to do everything, I will continue cleaning the whole screen once a week. For me, it was a real struggle maintaining water quality with just a fuge: starving my fish, super skimming, massive weekly water changes - just to keep Nitrates near 20ppm and Phosphate under 1.0. That all went away with an ATS, the hobby is much more enjoyable and not a huge chore."

Thedude657 on the scrubber site: "So my screen finally filled out with greenish algae. Water quality is excellent and now I have all sorts of cool things growing on my live rock. Little white sponges are popping up everywhere, some stuff I have no clue what it is yet. Just wanted to say thanks to help me get started."

Chrisfraser05 on the RC site: "I just wanted to jump in and say after bumping into Santamonica on a forum a while back and also watching Lafishguys videos I started a marine tank [8 months ago]. Obviously I started my first tank with a DIY algae scrubber and have NEVER seen either nitrate or phosphate."

Redneckgearhead on the scrubber site: "Heres the pics of my HA problem. [algea all over]These where taken just before I added my scrubber. I had tried EVERYTHING nothing helped. I paid a small fortune for a skimmer that I was told would surely take care of the problem. The HA laughed and kept on growing. My lights where down to 3 hours a day, my fish where only fed a small amount every two to three days, I was doing 10 percent water changes twice a week. And keep in mind those picks are only about 3 days growth, I would remove about 80 percent of the HA during my water changes. These are pics I took today just before my weekly water change. [almost no algae] I am feeding daily, my fish are now fat and happy. My scrubber is working beautifully! I am so glad I found out about scrubbers. I am still using my skimmer, but I may take it off line as soon as all the HA is gone. From the looks of things that shouldn't be much longer."

Fragglerocks on the RC site: "Ive gotten rid of 95% of all "bad" algae in the DT and my P04 Level is 0.12 checked by Hanna meter. Nitrates - Zero. I feed the equivalent of 2 frozen cubes per day, along with pellets whenever I think about it. up to 2 times per day."

Scrubit on the scrubber site: "have been running a scrubber-only 90gal tank for over a year now with great success. [...] I was ready to buy a big ol skimmer for my new tank build when I came across some of the info SM had posted. That was all it took, and I've never looked back. NEVER had algae in DT, NEVER had readable nitrates/phos after cycle, and have probably changed out maybe 40gal of water since setup. Personally I find running a scrubber almost as fun as the tank itself!"

Psyops on the RC site: "I had a DSB and chaeto fuge. When I added a ATS, the chaeto disappeared. I don't know if the DSB is doing anything. I feed my fish and tank from 1-2 times daily depending on my schedule. The ATS is doing really well, especially when I added a Calcium reactor 3 months ago. I did not believe some of the stuff people were saying on how effective an ATS system could be, but they were mostly correct."

JohnnyBinSD on the RC site: "I finally got around to putting an ATS on my tank 3 weeks ago. Just harvested a pile of algae off it tonight. In those 3 weeks I have doubled the amount of daily food I put in the tank, run the skimmer 6 hours/day instead of 24/7, and removed the lighting from the chaeto in the old fuge. Nitrates & phosphates are undetectable, algae in the display tank is almost nonexistent, fish are fat & happy. An ATS is the cheapest & most effective thing I've ever done to improve water quality. I wish I had built one sooner."

Kcmopar on the MFT site: "Its been about 5 weeks (started the weekend before fathers day) or so and the green hair algae has stopped growing in my 40G. Yeah!!! Its all receding, maybe just a few percent left at the base of a couple rocks that my coral beauty snacks on. Just amazing. Started this 40G salt from Jump with an ATS. IT NEVER CYCLED!!! I have little pods, tiny feather dusters, and other critters thriving like crazy. Coraline already starting to spread across the tank. Nutrients are always zero to just barely detectable on both the 10g and 40g. Also a note on the 40G, I never had to do a water change yet!!! No test results ever got past barely detectable. I have been dabbling with an ATS on a 10 gallon Freshwater as well. Same results so far. I am building a bigger one for my 150G FW in a few weeks."

Reeftanker on the MFUK site: "i have cleaned it about 8/10 times now, about 50-90 grams of algae each time and i have just tsted my tank i have on my test kits; Phosphates = clear that means undetectable levels on my test kit, Nitrates = 1ppm maybe 2ppm, what more do i have to say im am chuffed to bits and over the moon"

Etan on the MFUK site: "Just to share some of my results with my scrubber. I set up my new tank at beginning of Jan(Rio 400). The only filtration I have on the tank is a scrubber and about 50kg of live rock. After the tank had cycled my nitrates peaked at about 25ppm about 2 weeks ago. There were only 2 clowns and 2 chromis in tank and small cuc. Just tested today after all stock and cuc from old tank have been in there for about 1 week and nitrate reading is only 2ppm and not much signs of algee in main tank or on glass. It seems to me the scrubber is doing its job."

Weatherby68ss on the scrubber site: "i have been into this hobby for 3 years now and was using a wet /dry filter for the first year and a half or so untill i found out about algae scrubbers. i have to admit i would not still have an aquarium if not for my ats. its simply to much time, work and $$$ using any other type of filtration. with the ats i can actually sit back and enjoy my tank and keep my fish fat and happy with out worrying about the next water change because i hav'nt done 1 in over a year! :D anyone thats thinking about building 1 all i can say is go for it THEY WORK!!! nuff said"

Mgraf on the RC site: "I have been running a scrubber for about 8 months now, at first I had a skimmer running, macro's, rock rubble, and deep sand bed. Same setup as you almost. I still have the deep sand bed but, eliminated the other stuff over time for the sake of simplicity. I clean the scrubbers algae once a week, do monthly water changes, feed often and alot, and my corals and fish have never been happier or fatter in the year and a half it has been set up. Many may disagree but, for me it is the easiest way to run a salt water reef."

Jukka on the RC site: "I used to have various carbon sources + ATB Supersize skimmer as filtration for my 400 gal reef. I never succeeded to outcompete nutrient problems with those, no matter how much carbon I added. I also tried the pellet version. Since building a large scrubber with lots of light, all problems are gone. But I didn't take the skimmer out of the system and didn't stop carbon dosing, and don't intend to. I just reduced carbon amount to about 1/10 of the original. I like the effects carbon does for fungi, and other stuff like that, growth. Though other reason for keeping skimmer online is the amount I paid for the supersize ATB.

Some more successes from waterfall scrubbers:

Damon on the IM site: "I have been completely skimmer less for over a month now, and my ats has brought my nitrates from off the chart above 50ppm and with yesterday's test it has come down to 5 on the high end with color choosing(can't wait for a Hanna to make a nitrate). I am extremely happy with my ats as it is now, but I do believe I'm going to build a second one next to it. I built this size for a small (75-90g heavy bioload), but I'm going to add a second one that will be a more professional build quality now that I have figured out how I want it to run. I still love the fact that I have dropped $25 a month in electricity, haven't done a water change in a month while still dropping nitrates and getting amazing coral growth. The best part is I am making these to utilize my overflow drains, so in essence I adding a more efficient form of filtration without adding any heat or extra electricity. I can't report on long term results as I've only been running an ats since last fall. But from where my tank was to where it is now is enough for me to jump ship, lol."

Kerry on the scrubber site: "I was hard for me to believe that this device worked. It took about a year before I built one and now I wish I knew about this years ago. Who would have thought algae would provide so much success? I even have one on my 150G FW Jack Dempsey tank as well. And yes, its so nice not to have a skimmer anymore!!!!"

Reefkeeper2 on the RC site: "I run a skimmer, biopellets and an ATS. The skimmer and the pellets worked well keeping nitrates at 0, but there was room for improvement with phosphate control. I tried GFO, and lanthanum. My sps do not like the GFO. I got STN often when I changed it out. The lanthanum worked, but was very labor intensive and so unpractical. The ATS did the trick nicely. I have been a reefer for a very long time. I think I have tried every method of nutrient control thought up by anyone. I really enjoy trying out new ideas and trying to improve on old ones. I have to say that this combination has worked the best of all I have tried over the years."

N728NY on the RC site: "Just chiming in to say I really hope this thread keeps going! Lots of good info. I'm still pretty new to keeping a reef tank. I have been running a scrubber with my skimmer for the past three months. Before then I could never get my nitrates below 15, and since I added my scrubber I never been able to detect any nitrates, even after feeding twice as much. I know with my 75 gallon set up, I made my scrubber slightly over sized (sized for 100 gallons) and I dump huge amounts of pellets and frozen shrimp in my tank on top of spot feeding my corals on a regular basis and I still have yet to register any nitrates on my test kit. Being that I'm still new I still haven't built up the courage to unplug the skimmer yet. I may try it once I know for sure my scrubber is fully matured, got plenty of ro water made up and salt ready just in case I need to do an emergency water change lol. I still have a clump of cheato left that I suppose would be good back up if the scrubber couldn't keep up. The cheato doesn't really grow very much right now because of the scrubber. I love these scrubbers, I'm so glad I took the time to read "both sides" of the arguments on them to find out the facts about them."

Kentth on the scrubber site: "overall the tank is much healthier, a lot of feather dusters, coming out of the rocks, yellow sponges, other opaque sponges. big thing is no water changes for over 8 months, almost no silt, it has really cut my maintenance"

Langtudatinh01 on the RC site: "i completely redo my 40B with the ATS from beginning, i barely see much algae on my display tank but i now have a mature ATS. i relocated all my fish and add another one without any issue. the dead rocks i use bleach quite a lot of phosphate back into the water, but the ATS has handle the issue like a cham. i do not see much algae on my display. everything is green like grass down at the ATS. i am very happy so far.'

Bicolour on the MFUK site: "quick update, so my ats has been running since [6 weeks ago] and i gotta say all the algea in my tank and on the sand has gone, wow. gotta say it was well worth doing. i dont monitor growth at the moment but this is something i will be doing in the future, my set up was basic costing very little as i wanted to try this before i really looked into the idea. very impressed and can only say if you got space look into it"

Rysher on the RC site:  "i have a 6x9 screen, 1 inch is submerged so only 6x8 is really used, i also have a 40b. it has been my only form of filtration ever since i started the tank [months ago], i feed almost 2 cubes a day, only have 2 fishes but u cant see any algae on my DT, almost non existent film algae too, i clean my DT glass maybe once a week."

Packman90 on the RC site: "I have a 72 Gallon bow front and until a couple of months ago I was going to throw my tank away and give up on saltwater tanks all together. I was brand new, took a lot of advice, started my system and watched as it became more and more green, until i found out about scrubbers. I lost all of the coral frags I bought, about $400.00 worth, and just felt that I would never get it. I have it now, and just bought my first new frags in over 8 months. Thanks to all of you scrubbers out there who showed me the way. Here is the tank after the scrubber did it's magic. this took a total of 1 month for it to clear up, and I did not remove any of the algae, it just melted a way. Only problem I have is that i have some sea grass that is melting away as well and cheto in my sump is also slowly dieing."


Here is all the requirement for building a UAS

Screen material:
1)Use plastic canvas as the algae screen. Remember to roughen it up properly using a wood saw or hole saw. You can get plastic canvas at craft store (under sewing section) or sewing store or online at places like www.everythingplasticcanvas.com or ebay. Screen should look like this:

2)The lighting needs to be 1 watt per square inch (6.25 square cm) of screen material. A 3 by 4 inch screen is 12 square inches not 24. Make sure you have enough wattage and use a reflector if the light doesnot focus on screen. For fluorescent bulbs, it needs to have a spectrum of 2700k-3000k. For LEDs, it needs to be red 660nm. You can cut the wattage in half if you are using LED lights. In order for algae to grow, make sure that the light is on for 18 hours a day. Here are some bulbs and reflector type:

3)The bubbles need to be rapid and large and distributed through out the screen evenly for algae to grow. The best way to do this is by slicing the air tubing. Make sure the air pump is good so that the bubbles can constantly flow across the screen for 24 hours a day. This is why you need bubbles:

Some success stories of people who built upflow algae scrubbers...

ReeferMat on the MASC site: "So I decided to build one of these [UAS scrubbers] today. It's huge because all I had was a 12 inch airstone, but I'm hoping that won't matter too much. It cost me less than $20 to build, so if it works that is the best bang for the buck I have ever seen in the war on algae! It has been up and running for 3 months now and I have to say my tank looks a lot better. Every time I clean it it grows a new type of algae, slime, turf, etc... and it grows fast. I would say I have seen a decline in nuisance algae in my tank, but to be honest that would be an understatement.... It has all but eradicated it. Every time I look at the scrubber I can't help but think that all that junk would be growing in my DT"

Owenreefin on the PNWMAS site: "The first two months of running this UAS scrubber thing I was convinced I was going to rip it out for the algae growth was dismal, and I figured that my system just couldn't make it work. (I also have algae in my fuge) WELL I WAS WRONG. The thing started to really kick in. So much so that I just conducted my only water change in 2 months and I hardly think it was even necessary. I usually do a change of 30% every 2 weeks. My sand bed has cleared up big time too. With the water change I pulled out a good baseball sized amount of algae off the scrubber, couldn't be happier! I will always be running one of these. I will post pics of its growth next time I change water. Many months from now. :)

Bobba on the scrubber site: "Well, it's been almost 3 weeks with the HOG.5, and 2 with my lone Turbo snail. I am happy to report that I have no Hair Algae left in the tank. No signs of any regrowth of what the snail has eaten either."

Clavius on the scrubber site:

"I've been running a 500 liter tank now for 5 years. It is very well stocked with SPS, LPS, softies, filter feeders and a modest amount of fish. The nutrients were being kept very low by a combination of a giant skimmer and the ZEOvit method. Off course, this results in very lightly coloured corals, which was my goal. Generally I'm very pleased with the colouring and growth of my corals, and please with my tank in general. But one battle I've always lost: brown algae covering my sandbed. I could not, for the life of me, find what was causing those algae. Not to mention solve it. I've tried many many things to solve it, but up untill recently, without luck.

Almost three weeks ago though, I installed a HOG.5 unit. It was a little experiment that I wanted to do ever since I learned about algae scrubbers. I was never creative enough to build one myself, as the space in my 100 ltr sump is very limited. The HOG.5 was affordable and tiny enough to enable my experiment. I could even fit 6 of those units in there with ease. Off course, with the ZEO-method, my nutrients already were really very low. I couldn't measure any NO3 or PO4 with my Salifert test kits. And I never bothered with more expensive kits; unmeasurable should be good enough. I wanted to see if the vitamins and amino acids that the algae scrubber produces would add anything to my reef. And, more importantly, if the algae would consume "something" that the brown algae on my sandbed require.

The result in my sandbed is staggering. After only 3 weeks, not a trace of the pesky brown algae is left! An extra benefit, that I didn't expect, is that my lightly coloured corals now all have noticably much more colour. Without getting darker. They seem to glow! I don't know if it is from the vitamins that are released in the water [from the algae scrubber]. Or maybe the ugly brown algae [on the sand] were also covering my corals and that I now finally seeing my uncovered corals! Strangely enough, the algae in my HOG.5 aren't light green, as you would expect with nutrient-poor tanks. But they're a mix of dark brown with red tints here and there. So, I have no idea why that is or how that works. But at this stage I'm just so happy that I really don't care."

Има нещо като проклятие над този филтър, иначе изглежда ефективен, особено за морски аквариуми. Мисля че проблемът му е, че не е хай тек, а хората напоследък, ако нещо няма хиляда помпи и 20 контролера просто не вярват, че ще работи.

Аз лично го бях проучвал много сериозно преди време , но човек трябва да има съмп , иначе е грозна картина .  По-лесно е да го ползват соленоводни акваристи .
С добра дума и пистолет се постига повече, отколкото само с добра дума.

1982: The original dump-bucket style algae scrubber (works, but very hard to build, install, operate, and harvest)

2008: Waterfall style algae scrubber (works good but hard to build and install; must be removed to harvest)

2011: Upflow style scrubber (work goods, easier to build and install on the glass; must be removed to harvest)

2013: ??? (work great, all 3D growth, easy to build, and instant in-place harvesting without needing to remove anything or turn anything off).


If anyone has been waiting to build a waterfall or upflow scrubber, we will soon be posting plans of the new floating surface scrubber. It floats at the top and does not need a waterfall, and it does not shine through the glass.

Phosphate Flow от Rocks

Много хора , когато те ще получат тяхната scrubber движение за първи път , се притесняват , когато повече ( не по-малко) водорасли започва да расте на своите скали. Тя изглежда наистина странно , особено когато нитрати и фосфати са отишли (по-ниска) , отколкото преди. Какво се случва, е , че фосфат се излиза от скалите. Не забравяйте, че фосфат е невидим, така че можете да видите само на последиците от него, и то винаги се "влива " от по-високите концентрации на по-ниски концентрации (точно като топлина прави) .

Пример : Ако стаята ви е топло, и ще ви постави студен обект на пода , топлина от въздуха в помещението ще " потече " в обекта , докато обектът и въздухът са една и съща температура. Пример 2: Ако сложите горещ обект на пода , топлина ще "изтичат " извън обекта и да отида във въздуха в стаята , отново, докато на въздуха и обекта са на една и съща температура . Сега да предположим, че отворите прозорците ( през зимата ) . Топлият въздух в стаята си , ще излезем на прозорците , и тя ще получи по-студено в стаята. Предметът на пода в момента е по-топла от въздуха , така че топлината ще изтече на обекта и във въздуха , и след това през прозореца .

Мислете за фосфат като топлината , и вашите скали като обект , и вашите прозорци като скрубер . Както скрубер дърпа фосфат от водата , нивото на фосфат в капките вода . Сега , тъй като нивото на фосфат във вода е по-ниско от нивото на фосфат в скалите , фосфат потоци от скалите във водата , и след това от водата в скрубера . Това продължава , докато нивата на фосфати в скалите и водата са на едно ниво отново. И не забравяйте , вие не можете да видите този невидим поток.

Този поток причинява нещо интересно се случва . Тъй като фосфат излиза на скалите , тогава става достъпно да се хранят водорасли , веднага след като фосфат достига повърхността на скалите , където има светлина . Така че, тъй като повърхността на скалите е груба и има светлина , той започва все по- водорасли там ( не по-малко ), тъй като фосфат излиза от скалите. Това е доста невероятно нещо , за да видите за първи път , защото, ако вие не знаете какво се случва най-вероятно би си помислил , че водораслите в scrubber е изтичане и прикрепяне към скалите. Тук са признаците на фосфат излиза на скалите :

1 . Скалите са по-възрастни , и бавно са развили проблеми водорасли през изминалата година .

2 . Скруберът е нова, може би само на няколко месеца , и наскоро започна да се развива добре .

3 . Нитрати и фосфати измервания във водата са ниски, обикновено най-ниските те са били по-дълго време .

4 . Зелена коса водорасли ( не кафяв) на скалите се е увеличил в определени места , обикновено на ъгли и издатини в горната част .

5 . Стъклото не е необходимо почистване толкова .

Тъй като скимери , филтърни чорапи, и т.н. , не отстраняват всеки нитрат и фосфат, и waterchanges и макро в една фуга не отстраняват много, повечето хора никога не са виждали на последиците от големи количества фосфат , излизащи от скалите бързо. Но разбира се , го прави. Колко време продължи ? За 2 месеца до една година , в зависимост от това колко фосфат е в скалите , как вашата силна скрубер е , и колко други филтри фосфати отстраняване имате ( GFO , дозиране въглерод, и т.н. ) . Но един ден ще видите петна от бял камък, който са били покрити в зелена коса деня преди ; това е сигурен знак, че водораслите се губи тяхната доставка фосфат от скалите и вече не може да задържи . Сега това е само въпрос на дни преди скалите са ясни.

Phosphate Flow out of Rocks

Many people, when they get their scrubber running for the first time, get worried when more (not less) algae starts to grow on their rocks. It seems really strange, especially when nitrate and phosphate have gone lower than before. What is happening is that phosphate is coming out of the rocks. Remember, phosphate is invisible, so you can only see the effects of it, and it always "flows" from higher concentrations to lower concentrations (just like heat does).

Example: If your room is warm, and you put a cold object on the floor, heat from the air in the room will "flow" into the object until the object and the air are the same temperature. Example 2: If you put a hot object on the floor, heat will "flow" out of the object and go into the air in the room, again, until the air and the object are the same temperature. Now suppose you open your windows (in the winter). The warm air in your room will go out the windows, and it will get colder in the room. The object on the floor is now warmer than the air, so heat will flow out of the object and into the air, and then out the window.

Think of phosphate as the heat, and your rocks as the object, and your windows as the scrubber. As the scrubber pulls phosphate out of the water, the phosphate level in the water drops. Now, since the phosphate level in the water is lower than the phosphate level in the rocks, phosphate flows from the rocks into the water, and then from the water into the scrubber. This continues until the phosphate levels in the rocks and water are level again. And remember, you can't see this invisible flow.

This flow causes an interesting thing happens. As the phosphate comes out of the rocks, it then becomes available to feed algae as soon as the phosphate reaches the surface of the rocks where there is light. So, since the surface of the rocks is rough and has light, it starts growing MORE algae there (not less) as the phosphate comes out of the rocks. This is a pretty amazing thing to see for the first time, because if you did not know what was happening you would probably think that the algae in the scrubber was leaking out and attaching to your rocks. Here are the signs of phosphate coming out of the rocks:

1. The rocks are older, and have slowly developed algae problems in the past year.

2. The scrubber is new, maybe only a few months old, and has recently started to grow well.

3. Nitrate and phosphate measurements in the water are low, usually the lowest they have been in a long time.

4. Green hair algae (not brown) on the rocks has increased in certain spots, usually on corners and protrusions at the top.

5. The glass has not needed cleaning as much.

Since skimmers, filter socks, etc don't remove any nitrate and phosphate, and waterchanges and macro's in a fuge don't remove much, most people have never seen the effects of large amounts of phosphate coming out of the rocks quickly. But sure enough, it does. How long does it continue? For 2 months to a year, depending on how much phosphate is in the rocks, how strong your scrubber is, and how many other phosphate-removing filters you have (GFO, carbon dosing, etc). But one day you will see patches of white rock that were covered in green hair the day before; this is a sure sign that the algae are losing their phosphate supply from the rocks and can no longer hold on. Now it's just a matter of days before the rocks are clear.

Advanced Aquarist Feature Article for December 2013: Coral Feeding: An Overview

The picture in the article shows that in the 1000 litre test tank:

  98% of the food particles go to the skimmer when there are 2 coral colonies
  71% of the food particles go to the skimmer when there are 40 coral colonies
  92% of the food particles go to the skimmer when there are 2 coral colonies, when skimming is cut in half
  55% of the food particles go to the skimmer when there are 40 coral colonies, when skimming is cut in half

"This trade-off between food availability and water quality can be circumvented by using plankton-saving filtration systems, which include [...] algal turf scrubbers"

"Corals are able to feed on a wide range of particulate organic matter, which includes live organisms and their residues and excrements (detritus)."

"...bacteria [...] can be a major source of nitrogen."

"...when dry fish feeds or phytoplankton cultures are added to an aquarium, a part of this quickly ends up in the collection cup of the skimmer.

"...mechanical filters (which can include biofilters and sand filters) result in a significant waste of food."

"Detritus is a collective term for organic particles that arise from faeces, leftover food and decaying organisms. Detrital matter is common on coral reefs and in the aquarium, and slowly settles on the bottom as sediment. This sediment contains bacteria, protozoa, microscopic invertebrates, microalgae and organic material. These sedimentary sources can all serve as coral nutrients when suspended, especially for species growing in turbid waters. Experiments have revealed that many scleractinian corals can ingest and assimilate detritus which is trapped in coral mucus. Although stony corals may ingest detritus when it is available, several gorgonians have been found to primarily feed on suspended detritus."

"Dissolved organic matter (DOM) is an important food source for many corals. [...] scleractinian corals take up dissolved glucose from the water. More ecologically relevant, corals can also absorb amino acids and urea from the seawater"

Преведено от Google:

Какво направи всичко водорасли (и циано също) необходимостта да оцелее? Хранителни вещества. Какви са хранителни вещества? Амоняк / амониев, нитрит, нитрат, фосфат и урея са основните тези. Кои причини повечето от водораслите в резервоара? Същите тези хора. Защо не можеш просто да премахнете тези хранителни вещества и да елиминира всички водораслите в резервоара? Тъй като тези хранителни вещества са резултат от животните ви държат.

Е, как да ви животни "правят" тези хранителни вещества? Ами голяма част от хранителните вещества идват от пикая (урея). Pee е много високо съдържание на урея и амоняк, и те са любима храна на водорасли и някои бактерии. Това е защо си чашата винаги ще се нуждае от почистване; защото пикнята удря стъклото, преди всичко друго, и водорасли върху стъклото консумират на амоняк и карбамид веднага (с помощта на фотосинтеза) и да расте повече. В океана и езерата, фитопланктон консумират на амоняк и карбамид в открити води и водорасли го консумират в плитки области, но в резервоара не разполагате с достатъчно пространство или обем вода, за това, и другите си филтри или животни често се отстраняват или убиват фитопланктона или водорасли или иначе. Така че, хранителните вещества остават в резервоара.

Тогава амоняк / амоний удря си скали и перифитона върху тях консумира повече амоняк и карбамид. Перифитона е водорасли и животни, и е причината вашите скали променят цвета си след няколко седмици. След това амонякът отива във вътрешността на скалата, или удря си пясък, и бактерии там я превръщат в нитрити и нитрати. Въпреки това, хранителните вещества са все още в резервоара.

Също така нека не забравяме, фосфат, който идва от твърди органични хранителни частици. Когато тези частици са изядени от микроби и почистване на екипажа, на органичния фосфор в тях се превръща в фосфат. Въпреки това, хранителните вещества са все още в резервоара.

Така че, когато имате водорасли "проблеми", просто не са отстранени достатъчно хранителни вещества в сравнение с това колко сте били хранене (забележка:. Живо рок може да абсорбира фосфат за период до една година, което го прави да изглежда като никога не е имало проблем След това, има проблем).

Така че просто да увеличи отстраняване на биогенни елементи. Вие също може да намали хранене, и това има същия ефект, но със сигурност това не е забавно, когато искате да се хранят животните си :)


Nutrient Removal

What do all algae (and cyano too) need to survive? Nutrients. What are nutrients? Ammonia/ammonium, nitrite, nitrate, phosphate and urea are the major ones. Which ones cause most of the algae in your tank? These same ones. Why can't you just remove these nutrients and eliminate all the algae in your tank? Because these nutrients are the result of the animals you keep.

So how do your animals "make" these nutrients? Well a large part the nutrients come from pee (urea). Pee is very high in urea and ammonia, and these are a favorite food of algae and some bacteria. This is why your glass will always need cleaning; because the pee hits the glass before anything else, and algae on the glass consume the ammonia and urea immediately (using photosynthesis) and grow more. In the ocean and lakes, phytoplankton consume the ammonia and urea in open water, and seaweed consume it in shallow areas, but in a tank you don't have enough space or water volume for this, and, your other filters or animals often remove or kill the phytoplankton or seaweed anyway. So, the nutrients stay in your tank.

Then the ammonia/ammonium hits your rocks, and the periphyton on them consumes more ammonia and urea. Periphyton is both algae and animals, and is the reason your rocks change color after a few weeks. Then the ammonia goes inside the rock, or hits your sand, and bacteria there convert it into nitrite and nitrate. However, the nutrients are still in your tank.

Also let's not forget phosphate, which comes from solid organic food particles. When these particles are eaten by microbes and clean up crew, the organic phosphorus in them is converted into phosphate. However, the nutrients are still in your tank.

So whenever you have algae "problems", you simply have not removed enough nutrients compared to how much you have been feeding (note: live rock can absorb phosphate for up to a year, making it seem like there was never a problem. Then, there is a problem).

So just increase your nutrient removal. You could also reduce feeding, and this has the same effect, but it's certainly not fun when you want to feed your animals  :)
