    I bought some green zoanthids a few days ago, and everything was going fine. However, they closed up today and haven't really opened up since. It's a new tank, but my water tests say everything but my carbonate alkalinity is just fine. I got some reef builder for it, think that'll do the job?

    yeah that should help. my zoas get angry with low alk as well. i now put some buffer in my top off water to keep things stable.
