Kevvin27 on the LR site: "If I had known about algea scrubbers when I was first setting up my tank I would have started out with it right away. Everything in my tank looks so much better now with just the scrubber running then it did when I had a skimmer...and so much easier to clean and quieter too."
Rwing on the RA site: "Many of us have had the unfortunate experience of dealing with algae breakouts. For some these problems are a minor nuisance, but for others this problem can drive them right out of the hobby. In dealing with my algae problems, I became determined to educate myself with why I was experiencing this outbreak as well as how I could stop it and hopefully prevent it in the future. I hope that the experience that I gained can help others who are plagued by this nuisance. My plan of attack was to look at my home made filtration system and determine if I could make some improvements. I came across some articles about Algae Scrubbers that seemed very interesting. They looked really easy to build, and I thought "What have I got to lose?". I purchased the items needed to build it and had it installed in 1 evening. I used 2 5700k power compact bulbs and reflectors that I bought at Home Depot. I anxiously awaited for something to grow, and low and behold, in about a week I had a nice little algae crop growing. Within 2 weeks I was scraping it off, and have been ever since. I was starting to feel like I was going to beat this [nuisance algae] menace. When I [originally] started asking questions about controlling algae I was told to run a multitude of reactors and various chemical solutions. After reading many articles about algae, I chose not to run any reactors of any kind...I use 2 algae scrubbers to filter my water, I currently run a protein skimmer, and I do regular water changes . That is it, and my results have been remarkable! Sometimes I think we make things a lot more complicated than they really need to be. This entire process [scrubber plus some other changes] took about 3 months, but I can honestly say that my tank is now completely free of nuisance algae, and I am very confident that it will remain that way.
Slovak on the RA site: "In theory, all sounded reasonably good. How would this hold up in a real world application? The early adopters reported nearly too-good-to-be-true results. Just like everyone swore that all the approaches I already tried would work miracles. Besides, you can’t believe everything you read on the internet! Then again, what did I have to lose? I built my algae scrubber from 1/2-inch plastic tubing and a 8 1/2 x 11’’ plastic mesh screen found at Michael’s craft store. Two light fixtures with energy-saving bulbs and a timer for a total expense of less than $40. The results didn’t come overnight. I ran my skimmer in parallel for a couple of weeks simply because I feared a tank crash. The water flow and the lighting periods needed tweaking. For an impatient person it’s difficult to watch algae grow. Besides, there is nothing to clean as with a skimmer. After 4 weeks of this experiment I started to notice less algae in my overflows and on my pumps. 8-10 weeks and I could see the rocks again. My corals looked healthier, polyps were opening larger every week. There are many additional benefits from this approach: Less maintenance, as the algae screen is only cleaned every 7-10 days. I have even taken a 3-week vacation with only feeding and glass cleaning performed, and the tank was as beautiful as ever; There is also a significant cooling effect in the summer as the water runs over the screen. More energy efficient, as I traded a 50+W skimmer pump running 24 hours per day for 2 13W energy-efficient bulbs running 18 hours per day; The system is silent! One less pump injecting air into the water - nearly every visitor has commented on the quiet system - my office desk is 5 feet away from the glass; The algae growth is directly proportional to the load of the system and the amount of feeding. Once set up, there is nothing to adjust! My tank has been algae free for nearly 9 months. I perform weekly filter cleaning about every 10 days, with general tank cleaning / coraline scraping once a month. Water changes are back to 15 percent every month. All corals and inhabitants are very healthy. The anemone has split multiple times and the largest one is now over a foot wide. The hammer coral that started from a handful of heads is now over 10 inches in diameter and boasts over 100 heads. I now supply many local reefers with ample frags and my enjoyment of the hobby has finally returned!"
Vannpytt on the scrubber site: "since my scrubber started growing green, the polyps on the sps has been INSANE. During light off period (when light is on the scrubber) the polyps extend 5mm looking amazing. Later update: the tank is clean, the SPS are more than happy, a few of my Acros extend polyps all over the place, especially the milleporas, and the fish are fat. The Salifert nitrate test show <0.1 and the same with the Merck Phosphate test. Life is good. Skimmer is offline. Running carbon and doing a small waterchange every month to reduce the sulfate buildup when doing 2 part Randy's recipe. Going to take the carbon out also, just not yet. Had some startup problems with Acro's stressing out and RTN'ing each other. Seems fine now."
Donj on the scrubber site: "I would just like to add a little something about scrubbers, even though im not getting the green hair algae [on the screen] yet, the benefits so far have been incredible, the life in my system is thriving, the amount of little critters from having an ats is unbelievable, with lights out I can take a flashlight and see what seems to be millions of little critters. I have a 125 gal. tank with a fairly heavy bioload, with fish and mostly sps and lps coral, all are doing very, very well compared to when they were in my ninety gal with no ATS. About 4 weeks ago, I added a pair of mandarins (male n female), the male had a shrunken belly at my LFS, since then he has put some weight on, I would never have attempted this in a system thats been up for only a couple of months, its hard enough to keep 1 mandarin alive, much less 2, but there not only alive, there getting fat
, this is pleasing to me as this is one of my favorite species of fish. The coral growth is mind blowing as well, just gotta say thanks for your site, as I would have just kept on blowing more $$ on equipment I dont really need, had I not stumbled upon this site."
Craig1 on the scrubber site: "Thought I'd post an update. After over two months of use, so far, so good! Algae is growing nicely on the screen, more than enough to clean off each week. But for the results: Feeding at least a cube of food a day; 0/0/0 in the big three; Plenty of pods all over the place; No other filtration except for the rock; Almost zero algae in the DT (Few bubbles remain); Zero water changes in over two months; Have to dose Ca & Alk now, since not being replaced by the water changes; Coraline is growing like crazy now. For all the skeptics out there, the science works. Truly a revolutionary idea on the home tank, if done properly.

RumpyPumpy on the scrubber site: "My 55 gal reef system has been running for 7 months (I'd been keeping freshwater fish for 20 odd years previously) using only my home made (and probably not very efficient) scrubber (ok, for the first 2 or 3 months there was a bit of Purigen in the sump too but I don't think it did much). I have made no water changes at all over that time (obviously I have topped up with RODI water to replace evaporation), and other than food, I've only added Alk, calcium and occasionally some Seachem Reef Plus (still on my first bottle). The tank is not heavily stocked with fish, (a Yellow tang, pair of clowns, a coral beauty and five chromis) but I feed quite heavily (I think), everything is growing, the water is clear and I have only lost one fish since the start (a small clown which I believe was attacked by one or more of the other fish when introduced them). All the corals have grown and the hermits and other inverts appear to be thriving (although I did lose a shrimp too)."
New2scrub on the scrubber site: "my reef aquarium has never looked so good! I have built a scrubber that looks much like the sm-100 for my 45 gallon reef tank and the results are out-standing! the only thing that i do differently is i change a little water once a month, but not much. I have crystal clear water, pods everywhere, and have raised baby shrimp in my sump without any intervention! to me that is proof that scrubbers work well and provide much more food for the critters we keep!"
