Yea Params are fine as far as all cal mag. Nitrates are a touch high at 25 and phos sits around .08. I actually think it's due to lack of light. As I noticed I had a few polyps on each frag over an inch long. So I moved them closer to the light and will wait a week and see how things go. The reason I think it's lack of light is because I recently had to switch tanks do to a structural issue with the tank and went to a 40 breeder with a single xr15 so the edges of the tank are pretty dark and that's where I kept the zoas since I knew they liked low light. Apparently not that low though.Well, now everyone is going to ask for your parameters. All I know is that assuming they are fine, you will probably be told to try lower light and look for pests. I have had them become unhappy from being dirty, so try blowing them off with a turkey baster. Also, I recently found a small aiptasia because it was hiding on the plug and slowly stinging them to death.
