Are feeding them?

Not a lot. My other corals are starting to look mad also. Like I always can tell with my torches if something is wrong because they won’t extend as much and also can tell by the tissue going down I call the trunk is starting to shrink.

Hard to say for sure but if more than one coral is showing signs, I’d do a water change and swap out (or put in) some new carbon. Nothing in the levels you show indicate an issue, the plate looks like it’s bleaching too.

 

Also, make sure your heater isn’t broken and leaching crap into the water like mine did 😡

It definitely has started to bleach. Did a water change and changed out reactors. Heater is fine. The lights on my cheato reactor went out and took me about 3 days to get new one on there. Could the cheato dying have done that?

I'd double check your ALK.  My coral started to do the same thing a few months ago.  Turned out my dosing line got clogged.

I use Red Sea test kits currently but should have the Hanna reef set here today or tomorrow.
