My zoanthids are not doing so well. They have been shrinking for the last few months and have gotten to this size.
Why are they melting and what can I do to make them better? I have 3 ideas, but I'm not sure. This tank used to have some GSP (I took them out a few days ago), and from what I know, some soft corals can release chemicals that irritate other corals. I don't know if GSPs do this or not though. My 2nd idea is that there is too much calcium. I have had a bit of an issue with high calcium for a little while in my tanks. The last time I tested, calcium was over 500 ppm. My 3rd idea is that my nutrients have bottomed out. I don't really feed very often, that could have led to low nutrients. Can you help me make my zoas better please? I will post my parameters once I'm done testing.
