Anyone ever seen anything like this before (sps death)?

It could be. It remind me of the brown jelly disease.

I had a duncan that was wounded when fragged and was going that way. I removed it and put 3% peroxide directly on the affected area as it was only on the bony structure and not yet on the polyp and it recovered 100%. I would not do that on sps though, that would be the end of them.

Best way would be to check a sample with a 200x or 400x microscope. protozoare are easy to see and when I had this I could actualy see the protozoares eating the zooxanthellea of my coral! There was thousands of them.

It's sort of like a greenhouse with bugs and all you can do is hope they die out on their own or that the stock becomes resistent to it.

I hope that this is an isolated incident. Sorry, I realize I've said nothing helpful ... just that I sympathize (and empathize) and wish you good luck!!
