zoas never want to fully open as a colony

[cody125g]

I have a problem with certain zoas in my aquarium. My palys do good all the time but almost all the zoas in my tank stay closed. No pox or spiders or fish bothering them. I don't know what is going on..all my other corals are happy all the time other than zoas

As aways, please list all water parameters and what is your maintenance schedule. Also, how long are they closed and all other infos about your system.

You need to help your helpers here.

Bring down your photoperiod to 8 hours a day. Wait for like 2 to 4 days from now and let us know how zoas are doing… You could also, if possible, reduce the LEDs to about 20% of what you've got them going now...

off subject but, I noticed your sig says "can't polish a turd". Mythbusters polished some turds ;p and measured how shiny they were lol. So a turd CAN be polished
