Well, time for an update. Again, thanks to all those that have offered their help, condolences, and replacement frags to lessen the pain. I really appreciate it. I can't imagine how I stayed in this hobby for so long without the encouragement and support of other reefers.
On to the update:
Both the sinularia and nepthea are official DOA, as are 120 other frags that I pulled out, and 3 clowns. I've got another 15-20 frags that are basically dead, but have at least a tiny shread of tissue left on them, and at this point, I will give them time to see if they can hang on(I now have lots of room in what used to be a crowded system, so why not). I've got another 8-10 that seem OK and should make a full recovery.
Also, it looks like most, if not all, of my zoos will pull through. Nearly all of them were open and appeared normal.
The last WC that I did was on Saturday, another 40g, and as of today everything is inline where it should be. Rather curious that I did not get much of an amm. or nitrite spike, but I guess I curtailed that with the massive water changes starting less than 24 hrs after the earliest time the GFCI could have tripped. I'm checking levels daily for now while holding off on the water changes to see how stable the system is. If anything gets out of whack, I'll do another WC and put off adding frags a little longer.
On another note, has everyone tested their Reef Crystals? I did an alk test that I'm sure was bogus(will try again tomorrow), and my CA test showed 350!
