I think my tank is crashing. Bleaching and corals dying.

[Grandlotus]

So I put some of that reef safe putty in to kill an encrusted digi and then a few days later my pearlberry totally bleached and died in 1 day, now my red planet had a whole arm bleach and now one of my red staghorns is staring to bleach from the bottom up. I did a water change two weeks ago and just did one 5 minutes ago but all of my parameters are looking good.

Help? Ideas?

Are you running carbon? If not, I would suggest running carbon in just in case there is some chemical reaction going on. Helped with a brief episode of RTN I had recently that I suspect came from palys chemical. Took out a couple pieces and stopped halfway at the Red Dragon. Hope that helps

Currently running carbon in a media bag. I hope this stops soon. I am getting worried. I will probably do another WC.

Any Changes recently? Alk swings, are you dosing and what are you dosing with?
New additions, recent sand cleaning, new rock, stray voltage. All questions to ask and answer.

I do not think it is the putty, I have used about 6 different brands of epoxy including one from home depot. When you were doing the epoxy their mush have been somthing else changed. Gravel removed, stirred, pearlberry are very sensitive to kh change.
