couple things:
blasting your zoa with mysis isnt going to make it open
although zoas sure can stay closed for long periods of time a healthy zoa should open within a half day of being in a new tank.
i doubt its nudis
check for zoa pox
i notice you have a mp10 in a 33g, what setting and percent are you running it at?
how new is this tank?
your temp is way to low which is a big contributing factor with zoos
alk is also way to high for zoos
those are your two biggest red alerts going off for me.
