Got a frag awhile back that had some on it and I thought I got rid of it. But after a while I saw new buble algae growth on the frag, so i again cleaned it. Today I noticed it was covered yet a again all the around the rim of the chalice. And upon closer inspection it has now started to spread. i have pluck out the ones that where easy to get to but a ton is still attached to parts of the tank I can't safely remove.
Any ideas on what to do?
