Zoanthids turning grey

[LiLinka]

These gmk zoas are discoloring. Some polyps are turning a pale grayish color. Parameters:

Alk: 8.0

cal: 475

mag: 1475

phos: 0.05

nitrate: 0.3
Salt: 1.026. Did have an issue with the salt raising to 1.030 for a couple of days but it’s corrected now. Could it be due to this?

They have been in tank for about 2 months. Started from 1p grew like crazy now are just sitting there discoloring. It could also be a trace element issue is what I’m thinking but would like to hear other peoples opinion. Thanks!

I’m far from a pro but my guess is salinity. From what I understand your tank can handle going down but not when the level goes up. Hopefully they pull through
