Had one of these on saltwaterfish for my 6 gal SW tank, and it helped a lot! Ok, DAY 1. Set up Aquarium on its stand, set up a 4" deep sand bed with play sand, filtered sand so the really fine junk was gone, Aquascaped, filled with water, Installed lighting. I added some chemicals to the water, but I forget exactly what they all were.... I know one was plant gro or something.... I'll edit tis tomorrow when I check. Made and revised stock list. here's what I have now: 5 Kuli Loaches 1 Pearl Gourami 2 Clown plecos 5 Congo tetras 5 African dawrf frogs 2 wood shrimp. I have a good idea of where to go from here, but tell me if theres something unusual that I might forget. Thanks very much!
