Looking for some guidance on tank perimeters

[MollyDog]

I’m just curious as to what people think if my tanks chemistry atm. Zooanthids seem to keep disappearing. Trying to figure out

Possibly the low KH?

P04 looks high but that shouldn't kill zoas.

How old is your tank?

Your parameters look fine (if they are accurate). Zoa's are typically pretty hardy and only really suffer from lack of nutrients or predators. Again your nutrients are fine, even elevated in the case of PO4. How are you testing salinity? What are you using for lighting? Have you seen anything on your zoa's? Lastly, how old is the tank?

Sorry for all the questions, but the parameter results you are showing don't point to a cause.

Your params are fine. Natural sea water is around 7.7 dkh.

Something else is bothering them.

My tank is 7-8 months old now, everything else is growing and is fine. Not sure what would be bothering them but I hardly ever see any growth and looks as if every other month there’s another pylop disappearing but I have some palysthoas that seem to be growing new heads? Maybe I should try and dip the frags in question? I test my salinity with a refractometer.
Thanks

I agree that the reported parameters seem fine.

Starting to think it might be a possibility that it’s a pest of some sort?
