Using a 20g fish tank as an algae scrubber is really hard to work with. Put the light outside the tank and it's too far away. Try to put the light inside the tank and it doesn't have enough room to squeeze the light in close enough. Finally changed the single line design to an "L" shape. Now I can have all 4 lights close enough to the plastic sheets.
My first attempt was just to feed the water from a horizontal T split from the overflow. It just didn't have enough flow. Most of the water went straight down to the sump. Worst yet, one of the glued joins has a tiny leak! :grumble: I was like screw it. Since I have enough flow and enough outlet from my return pump, I just hook the feed from the return pump. I turned the valve half way but the flow was not impressive at all.
I went up stairs and check on the DT overflow and it is at the "normal" level. The water was within the normal overflow slot height. That's too weak for my taste. :D
So, I changed the last support leg with a Quiet One 1200 pump. It should have about 200gph at 2 feet. One side feeding the water from the main return pump and the other side with this small pump to recycle the water. The flow looks much better now. :)
Here is the L shape Algae Scrubber with 4 lights and a fan on top. I also used my old algae scrubber sheet sandwich in there and hope it can seed the new sheets to grow faster.
