I see you still have some Ammonia in the tank. Hopefully it will balance out. I will say however it doesn't appear the zoas are just melting. They are an odd color though. So what I would suggest is to try a feed just to see. Maybe do a little reef roids. Or supplement with Brithwell aquatics Coral Amino or Red Sea Ab+ Or all of the above. Just my thought. I've never had this issue b4.
I'm pretty sure the ammonia is from a false 0. It read 0 with my old test kit. My nutrients have balanced out pretty well. I have fed reef roids, and used seachem's reef + none of which have made a difference.
What color were they to start? Often I find that small zoa buds on frag plugs may have a different color/pattern compared to fully grown ones.
AI Prime - schedule/levels attached to original post. There is some fluorescence, but not much at all.
they do now, but the only difference upon arrival was coloration.
