Something that I can't figure out is as to why my 300g 96x30x24 still has cloudy water after 10 months. The fish are very healthy and no other problems have come up. Isn't 10 months long enough for a tank to be established? Should I try using that Accu-Clear stuff? I have to say that the cloudiness of the water has taken much of the joy out from having such a large tank.
