Zoas affected by high DKH?

[Ramon Estevez]

Alright I’ve been testing my tank and the ALK has consistently been 11-12, PH 8.3, Nitrates around 2, Phosphates .04. I’ve started dosing VItamin C, for about a week now and I also treated with revive to make sure there were no pests. Yet the Zoas just look awful my LPS look great I’m not sure if the High ALK is just pushing there limits...

I have noticed some of my zoas like nitrates around 5ppm while other don't need any. I have not noticed phosphates affecting to much either way. Vitamin C dosing did nothing for my retracted zoas/palys.

I had a tank that accidentally got far too high of an alk level and the zoas would not open up until the alk was brought back down

How high?

I guess that’s what I get for getting salt 2nd hand without knowing the brand...

Well, I personally don't think it likely that 11-12 dKH is causing the issue, but I was waiting for others to post who focus more on zooanthids.
