I’ve had these zoas for awhile and I’m seeing very minimal growth from all my frags/ colonies in this tank. This colony is the only one of my three types of zoas that is infact loosing heads. My amonia/nitrate/nitrites are 0, and I know these guys like “dirtier” water but would that cause heads to be lost? Lighting is Kessil a160 tuna blue that max out at around 50% and coral is in the lower half of the tank. Please help!
