That's the only question that really matters. I held off posting anything until I had been running for long enough to answer that question. There is no doubt in my mind that my SPS corals have improved tremendously since I added the algae scrubber. Colonies that had shown no growth for the previous year are now growing like mad. Bright new growth tips are popping up all over. My LPS remain unchanged. The only downside I've noticed is that my red milli has become paler in color, not sure why. My blue milli is unchanged in color and growing faster.

As for nutrient levels, I use a spectrophotometer from work to conduct my nitrate and phosphate tests. Nitrate and phosphate are pretty much undetectible now, although they were never very high. I don't put a lot of stock in test results. How the corals look, how much hair algae and cyano I have is more important to me.

I'm not trying to advocate algae scrubbers. I'm just trying to share what is working for me. I tried the zeo approach and the bio-pellet approach, with RowaPhos, and they did not work for me. Nutrient test results were low, but hair algae was rampant and SPS growth had ground to a halt. I have a lot of fish in my tank, probably too many, and they have grown a lot in the past three years. Loonie-sized fish three years ago are now 8-10" in size.

I tried this out of desperation and it is the only thing that has worked so far.

I think I have a design in mind. My question is. I run a gfo and carbon reactors. Does anyone see a issue with using there output for my water source. As it would eliminate the need for another pump. I thought of using my over flow but that would mean another light. I was planning on running this above my refuge and draining into.

I'm sure many are skeptical due to how 'santamonica' force-fed this to the web on 80 different forums and his subsequent banning on some of them. I'll admit I am still intrigued. I run gfo and could make it last longer with one of these in operation. I recently added chaeto to my sump but my instincts tell me this will grow algae faster. Unlike bio pellets there's no way this can be limited or messed up by running the gfo... it can only allow the media to last me longer.

I'm curious which algaes in general remove more nutrients by mass.

Any shots of the components apart?

Well it's nice to see the results finally, I just started running rowaphos but am going to be building the same type of unit soon. Just gotta find a free weekend and may wait till it warms up abit to start this project. I will post pics of my mini scrubber on here aswell if you don't mind.

chaeto and calupera are the best but calupera requires calcium as well so you may need to dose more.

i think chaeto would do almost as well as an ATS if you gave it as much light. Everyone puts a small ass bulb over the fuge so only the surface of the chaeto will get light. if you keep the chaeto moving in a tumble then all parts of the chaeto get light and it will be more effective. Throw four t5's over your fuge and get the chaeto tumbling and then you can compare an ATS with a chaeto fuge. Otherwise the ATS will always win (higher flow, more light, greater surface area)

As long as you have enough flow, you should be fine. Any excess nutrients will sustain algae growth.

I remember the 'santamonica' banning etc as well. The reason I chose to go with the scrubber vs chaeto was the space I had available. I couldn't figure out how to incorporate a chaeto fuge.

I don't have any pictures of components apart. My acrylic box is 24" long, 12" high and 3" wide. I cut two 1" bulkhead drain holes in the bottom and a semi-circle groove in each end to support the supply tube. The lights are 4-24" dual T8 fixtures from Home Depot.

I have been running a scrubber for month now and it works really well. My phosphate and nitrate are at 0 consistently for the first time in 6 years. My fish and corals like the extra food they are getting as well.So easy to build and effective.

Ive run a scrubber since spring, or may be early summer. I have the top of my mesh up inside the slotted pipe and attached with fishing line. To clean it I just remove the pipe with the mesh still attached. We all know how fast GHA can grow, but its amazing how much you can grow in 2 weeks on one of these things. I also run carbon and rowa with no problems. I do get alot of particulate in my water. The waters clear , but always with little bits of stuff floating around. Ive been running skimmer less since I set this up, but lately Ive been thinking of adding a skimmer to remove this stuff. I know alot of it can be eaten by the corals , plus my euro reef bit the dust, so I would have to by a new pump, or a new skimmer. I'm kind of on the fence here, but I wouldn't mind seeing how both together would work.

ok well i went and got all the materials today to build a algae scrubber, once i start building i will start a thread for the build and then to monitor the results and we will see how fast we get results, right now my phos is controlled by gfo but my nitrates are around 40ppm .

im thinking that instead of zipties onto the main pipe that my water comes out i will use a smaller size pipe that the mesh will ziptie onto, ill just shut off the valve,remove the end cap and slide the pipe out,ill make abigger otch out of the smaller pipe so it doesnt restrict flow but it only has one output anyways so i dont see that being a problem.

ill run to home depot later and see what they have for lights but besides that i have it all.
