I have a large mix cichlid tank and I am haveing a problem with Tiny particles floating around in the water. I have macanical filtration in the form of sponges I think they are 40 PPI and I run filter floss in a reactor. I have a lot of water flow, the turn over rate is over 10 times the tank volume. The next thing I'm gonna try is floculence but wanted to ask on hear of there is a better way, as I don't like to add chemicals to the water if I don't have to. I have tried to clean the macanical filtration everyday for over a week to see if it would get better but it did not.
