IMHO

I dont think its something from just today, tissue errosion seems to happen two or three days after a significant event.

The tank I had drop to 65 degrees was fine for two days or so it seemed, on the third day I had rapid tissue errosion.

I fragged some of the colonies and some were fine, others were a total loss, id say 55% of the frags have survived.

It must be associated with water quality and something has changed in the last few days, pH ?, sG ?, temp ?, etc., etc. since most dont keep track on a neptune or some other charting system its hard to tell what has changed but its not just a freak of nature.

Again only my HO.

Sorry I cant be more of a help.

PS Why the phosphate sponge ? was it high phosphates tested or just some other sign of high nutrients in the water ?

Broken heater ? or something else leeching into the water ?
