I have a 60 gallon with HOB, mostly softies and a couple of hammers and candy cane. I just returned from a 10 day vacation. I had someone feeding my fish but no other maintenance. Everything looked great other than some cyano and GHA, which I try to clear out on a daily basis when I'm home.
So yesterday I did a 5 gal water change and scrubbed and sucked out the GHA as normal. There was a decent clump of GHA encroaching on my GSP and some zoas, so I turned off the pumps and dosed it with some H2O2, maybe 5-6 ml. I let it sit a couple of minutes then turned the pumps back on. I've done this a couple of times before with no Ill effect, although I may not have used quite so much H2O2 in the past.
Note that this is the first time I've used H2O2 since adding a condylactis, BTA, and rock flower nem to the tank. These are the first nems I've ever owned, and they've been thriving. None of them have ever moved since being established a month ago.
Within an hour or so I noticed the nems closing up. As it was getting late and the lights had begun cycling down, I didn't think too much of it. This morning, nearly everything in the tank is severely shriveled up or missing altogether. The BTA is nowhere to be found. The condy had dropped loose and was being nipped at by a clown which has never paid it any attention before. It was secreting a milky substance. I moved it immediately to my QT tank.
I performed a 15 gal water change, which is all I had prepared on hand. I also dropped a new charcoal pack into my Fluval C4. But after several hours, everything still seems to be going downhill. Strangely, it's just the corals. My fish and invertebrates seem to be unaffected.
I have a toadstool leather that looks a little shrunken but has good polyp extension, and my GSP and Kenya tree look marginal. But my hammers, mushrooms and Xenia look terrible. All zoas are completely closed up. The rock flower nem has a gaping mouth and is all drawn up.
Is there any hope at this point? Obviously the H2O2 was a bad idea, but did I simply use too much or did it shock the condy into releasing its toxins and that's what has zapped everything else? Any suggestions other than continuing water changes to try to save them?
