Hi there, looks like you just joined as well so welcome aboard as well!

How old is your tank?

How long have you had the zoas?

What are your tank parameters?

Thank you.
My tank is 3 month and the zoas have been 1 month.
I have other zoas and they are perfect.
The parameters:
NO3 - 0
PO4 - 0,03
Kh - 7

NO3 is Low, I dont know If It is the problem. The other zoas are perfect.
Thank you.

Zoas spitting their guts out. Never seen them recover from this. Idk what causes it and all the zoa collectors i have talked to can't for sure determine what makes them do it.
