Thanks. Another question. What kind of glue so you use? I read that some just use super glue. I bought Cg Coral glue from my lfs but I really don't like it.
The coral shop I buy from always sends me a free container. I'd recommend against toxic superglue. Only use coral glue of some kind. This is what I use...
Blow on it for a good minute before placing it back in the water. It needs a bit to set. I usually place a blob onto the disc or rock first. Give it a minute before placing the coral into the glue, then another minute to let it set.
I usually out the glue on the disc the coral is on. Maybe I am not waiting enough time. I am worried it's going to harden before I can get the coral back in the tank
