I'm almost afraid to report that we have a partial victory! I had a monti cap that I thought was dead, but due to laziness I had left it in the tank. 6 days ago, as I was going through the tank, I noticed the frag has polyps and skin! At that point, I wasn't sure what to make of that (was the frag still slowly dying or is it trying to come back? So I took a picture.
I've been taking pictures every night of that frag, and it is clear to me that it is growing skin over the dead skeleton AND calcifying new skeleton!!!
First photo:
5 days later:
There are a few places where it is very easy to see the growth, but when you flip the two photos quickly it is pretty crazy how much has grown in 5 days!
Also, I had a chalice that was all shriveled up and losing skin, but around the same time, not only did it stop dying, it is fully puffed up now and almost always extending small tentacles out!
Now the question is, did I fix the problem, or did my 50% water change just dilute it enough so that these corals can catch a break?
I'll be doing another big water change today because I'll be away for 2 weeks, so we'll see what happens.
On a side note, since I've stopped the gfo, I've noticed some patches of cyano building up. I'll suck it out as much as I can but I'm just scared to not let the nutrients go too high and go to the other extreme.
Should I put a small bag of GFO in the sump (not in the reactor)?
