Ok. I give. I thought this Zoa colony was bouncing back after removing a couple vermetid snails. But it continued to have polyps melt away. I thought maybe it was too shaded so I moved some rocks around. Still melting away. I changed the position of the rock the zoas are on and they look very unhappy now. I totally suspect the move to be the cause of that. The majority of the polyps are open but they don't look full like they used to. They haven't in a long time.
Everything in my tank looks great right now besides this colony of zoas.
Parameters are:
Temp 78-79
Ph(currently):8.47
Mag: 1400
ALK:10
Calcium:420
Nitrates: 5-10ppm
Phosphates: card says 0.25
I guess I'm gonna try and dip the whole rock and try and kill any left over vermetid snails. Other then that maybe reduce the lighting intensity? They are still at the same level in the tank just angled so now they all get even lighting.
