Help save my colt coral...

[MikeP]

I don't know much about any type of coral yet but I bought a piece of LR from somebody and he said it had a colt coral on it. The colt coral wasn't doing to well cause his tank sitter didn't know what he was doing. Anyway this guy was taking down his tank and I bought this LR/colt coral. It looks in real bad shape (just slumped over). What can I do to help it? I have some coral builder and some phytoplankton. Should I buy some iodine? Some people swear by iodine and some say it's over rated. I should mention my tank is 30g and has 55 watt, 10000K PC lighting. I have had a pulsing xenia for a few weeks and it seems to be doing fine.

Thanks for any help.
