What will I see if:
pH is out of whack? Closed/Open/Melting away/growth explosion?
Calcium is low?
Alk?
Mg?
Etc.
I would really like to see a thread with chemical parameters, and what can be expected from each. Photo evidence would be helpful.
As to the topic of keeping this thread alive, PICTURES! Holy heck! Zoas can be some of the most colorful corals in the tank, and people really salivate over pics. It's the only thing that jump starts a thread in any of these forums. It's so boring to see a thread that says, " my zoas won't open" then the answers are read the sticky thread and fix what's out of whack. Sorry but it's just plain not helpful. I understand why there needs to be controls in place, so that everytime a guy posts a pic of his really cool zoas, it doesn't just disintegrate into "PM me when you're ready to frag them" But really more pics shake loose the guys who would simply post, "Nice zoas" and keeps them active.
Just my rambling. Take it for what it's worth.
