Hey guys I have a relatively new 10g SW tank with Zoanthids and Alveopora. Everything was reading zero until about 3 days ago my nitrates were kind of high.
I've been using advice from forums + LFS. So if i'm doing something wrong, please be kind I'm somewhat new.
They wouldn't open up today, even after a few hours after turning on the lights.
After today's 30% water change they were at 2-3ppm and the coral still didn't open. My pH was 8.2.
I also added calcium and iron (the RODI water I get doesnt have those elements)
Am I missing something or am I overdoing something?
I fed the alveopora phytoplankton yesterday.

10g SW
