I have a 29 gallon reef with 30 pounds of live rock and a 2 inch live sandbed with a fluval 405 and a aqua c remora rated for 75 gallons and a KOralia 1. All i have in the tank is a yellow tail damsel and a hammer coral and a couple zoo frags yet my tank seems dirty the water is hazy and not crystal clear and the whole thing looks dirty. Have have 15 hermits and 12 snails. I just dont get it.
