Hey guys, I’m having some issues with my zoas and I can’t pinpoint the issue. These corals were all open and looking happy and then quickly started melting. My little shop of horrors which I received about a month ago is left to one polyp out of 3 and is completely closed up so that was $275 down the drain. My parameters are as follows, alk 8.5, ph 7.7 currently, salinity is 1.025, ca 481, mag 1329, nitrates are 20 ppt, and phosphates are .05. Nothing has changed that I can recall other than changing out filter socks. I’m going to do an icp test in case there’s heavy metals but I’m running carbon which I’m hoping should catch anything. Anything else to check? Also I dipped all my corals and did a fresh water bath for my zoas. I have one acro in my tank and that looks like it’s doing fine. I don’t see any nudibranches or spiders or anything else on the zoas so not sure what’s wrong. See before and after pics. The highlighted circles are of the zoas not doing well.
