LPS corals receding

[Animal-Chin]

Personally I'd stop dosing foz down or any other chemical that you're using that isn't just the basic alk, cal and mg. I find if I use any "reef safe" treatment for anything I'm gonna loose a coral or two.

Are your Scoly's under direct light? maybe shade them a bit.

I'd suggest a big water change or two but I know thats hard with your volume of water especially if you aren't making RODI at home. Still when things go buggy I like a couple of big water changes to remove anything that may be in your water.


Are all your other coral totally fine? What else do you have? Do you have a lot of coral and its just a couple that are going bad but everything else is fine?
