I have had my 75g tank setup running for about 4-5 months now and for the life of me cant get my water 100% clear. I do 25-40% water changes every and sometimes throw a 15% water change in there mid week. I use prime to declorhinate the water. I have a canister (bought from topdogsellers on ebay, thought i would give their can a try before investing into a better can)and HOB (think its emperor 400 cant remember name lol) running on the tank. I have 5, 2-3inch A. Lyonsi, 1, 4inch severum, 1 pictus cat, a 3inch FM that was just recently added, and a 7inch Chocolate cichlid that i just got yesterday. The problem im having is that the water is pretty clear but i have these small white speckles floating around the tank making the water slightly cloudy. I dont think its a bloom because its been there forever even after the tank has cycled. Any body have any tips or know of a solution?
