Where do you have it in the tank? High? Middle? Low? On sand? Zoas don't need tons of light, they might be getting too much light where they are.

How much T5? Duration of lighting?

How about your alk?

did you mean your nitrAte was 0.1? Or you have detectable nitrIte? If you have detectable nitrIte that is a problem.

Are there any other corals in the tank? If so how are they doing? Especially any other zoas that are doing ok? Have you examined the zoas closely? I had a colony get zoa pox and it dang near wiped out all the zoas in my tank - probably 200 heads.
