Hello,
I am a pretty experienced Reefer, who’s never had issues raising zoas. For the past couple weeks, all of my zoas have closed up. The rest of the corals in my tank have been super happy. I recently bought new zoas from the WWC sale, and they were open the first day I got them, and will not open up after that. I don’t believe it’s a flow or light issue, as I have them at the bottom of my tank. I run a 6 bulb T5 fixture.
Levels:
Salinity: 1.023
Nitrate :0 (however have a little bit of green algae)
Phosphate: 7.8 (yes this is a little low, but my tank has always had low phosphates)
Phosphate:0
calxium:400
Alk:8
I just added a bunch of new fish and am trying to increase nitrates as I believe that could be my issue. Any other suggestions?
