I have 2 small colonies I recently got that are both paly types. They've gone into full closure for a few weeks now. The only possible irritant I can see is a small build up of what resembles "diatoms" (even though it's likely not diatoms) on the closed polyps. I'm thinking of actually taking a soft toothbrush and seeing if that will help shed the funk. Not sure what else to try at this point. any suggestions?
thanks,
casey
