I've read this forum for a while and I decide to try the scrubber. I keep tanganyikan cichlids for 10 year but I'm new to reef, but I've read on it everyday. I want to try with a 5.5 gallon tank, I will do the DIY nano scrubber kind of Santa. If I understand it right, I was thinking of having a one side 5x5 in screen, with a 200gph pumps (maybe a bigger pump). For the light I'm not sure, I would like to go with Led. I was thinking this led from ebay http://www.ebay.com/itm/DIY-3-x-3W-Red- ... 336ca82f56 but I don't know if only one set would do the trick or if I should go for 2. And if I need something else to plug this led. Sorry for my poor english!!!
