Mine have been closed up for about a mo now. The Nit, Trates, cla,mag, alk,ph ck out. So can anyone tell me what is going on? I have 520w compact lights in my 75, wet/dry,protein skimmer. I have tried target feeding but to no avail. They are the green zoa with the brown edges. Unable to provide pic. Santa nvr brought me a camera for Christmas!
