i have some polyps that died on a piece of my live rock and i just turned it over so you cant see the dead polyps if i just leave them there will i hurt my tank or should it be ok
hard plastic brush like for cleaning your toilet or drinking glass. (make sure its new) and dont do it in your tank.
Or you can scrape them off with a knife as much as possible out of the tank
Just out of curiosity how did they die? Are you 100% certain they died because if not they should still come back because the polyps might have died but their seed layer is still there unless that died too
