A couple of questions if you don't mind my asking. What kind of lighting do you have and what re your parameters as far as the basic four go PH,ammonia,nitrite,and nitrate?Also are these soft corals or stony corals? I know when I have SPS in a tank that is not as well lit as its previous tank it can get a little browned out. The same thing can happen do to too many phosphates and nitrates.
