I have a 110 gal that in the last 3 1/2 weeks has gone from clear to a very fine greyish white foggy look. Now here's what i''ve tried to do--I have 2- 3 stage filstar canisters that i completely cleaned and changed media on 3 times so far, did about 30% water changes about 5 times, put water clarifier to try and clump the fine particles , all the fish in the tank is doing fine- about 5 large severums and a mixture of about 10 other medium size fish. Water checks out fine. I have some crushed coral in with some other substrate. I'm in the process of changing the substrate out, doing it slowly as to not crash the tank.Any ideas out there, I'm not a rookie at this but i've tried about everything i know. AND THE WATER IS STILL FOGGY??? Any help or advise ? Thanks.
