Colonial hydroids....they suck! I usually pull the rock and with a lil hand held lighter torch I use fer shrink wrap tubing I burn em!

Making a paste with kalk and covering them with no flow I've heard works too. I had them in a tank but they stayed in one area and didn't take over so I never bothered. I've heard they can be a nightmare though.

Thanks for the info ya I think I'm going to try the kalk Cuz I have corals stuck to the rock its on n I'd really hate to kill any thing on it
