i have a 55 gallon fish tank i have a whisper 30 -60 and a aquatech 30 - 60 power filter on it. i also have a powerhead and a undergravell filter. I have one albino oscar a 16 inch algea eater and a very small african chiclid. My tank is SO CLOUDY i can't even see in it, i have checked the ammonia, GH, KH, PH and everything else i can think to check everything is perferct. I washed all the gravel and cleaned it before i put it in the tank the tank has been set up for about 3 weeks now and its just getting worse. I have tried water changes but they don't seem to help. Any ideas on getting this thing to look halfway decent??
