What could be wrong with these zoas and palys?

Good to know. Little evil buggers, most times you can not even see their subtle little nips.

 

Glad you found the problem zesty, those palys are awesome! Keep up with your dosing, you'll be amazed.

 

have you noticed differences in your corals since starting the aquavitro dosing?

 

I've actually have not needed to dose that much. The only thing I'm doing is bringing up my Alk. I realize that my coral load doesn't take out enough CA & Mag to need to supplement that. My water changes are enough to supply the CA & Mag that my tank needs at the moment. I think I'm ahead of the learning curve here and that will be a first!

With that being said, things are looking good in the tank. So, maybe just paying attention to the big 3 params and trying to get as much stability as I can is helping.

I know, such a wishy washy answer. ;D

 

yeah, he's a bugger for sure!! I realized when I used the trap he was the most food aggressive and was right over there trying to get the pellets within seconds!

 

What's an update without pictures? Here are 2 out of the 3 zoa colonies that have made a good comeback. The 3rd is doing ok...



Thanks all!
