where did you get your live rock from. Alot of time is from the live rock you get. Cause me and my wife have the same everything. BUt my tank I got rock from alamo(I know IM dum) I fight it all the time. MY wifes tank nothen and I got her rock from other store. but we use the same r/o water and but we use differnt lights but mostly the same kinda wattage. I think it mostly came from the rock.
