Major zoa problems


New Member
Was a member here 7 or so years ago and back in the reef game.

Anyways i started a 29 biocube and couldnt be happier being a reefer again. However i cant seem to keep zoas alive like before. Tank has completed 3 month cycle and water perams are as follows.

Nitrate/nitrite/amonia 0/0/0
Ph 8.4
Phos 0
Alk. 3.2
Bi-weekly 10G water changes using reef crystals

My Acan Lord and Cyphatrea are happy as clams ( pun intended) zoas will not open nor will palys however my very large protopaly is open and happy being fed.

Any help very greatly appreciated

Salinity 1.025 tested with refactometer
Water temp 78
Dont have calcium test kit also do not dose for it
Water flow i would say is medium compared to my past sps tank.

Alk was a huge typo and i apologize actual is 8.3 dkh. Dont know how i screwed that up so bad.

Did a 50% water change in hopes it was an irratant but only my acan enjoyed that.

Ive got them to open a little so they show color but nothing more also My palys have opened and are very very happy since doing a 50% WC which i knownisnt ideal but my Acan and meteorshower are super happy and zoas just seem to be teasing me lol.
