Cloudy water


New Member
Hey guys, I'm new here, I've got cloudy water in my 55 gal marine aquarium and can't get rid of it. I have never had this problem before. I'm stumped. I've done a water change. Cleaned my filter with new charcoal. The only thing I've done different in the last month was add some dry purple rock from the pet store. Any ideas ?
