Alright thanks, I think I'll put it In vinegar for a while then wash it out just in case it's coralline.

Sometimes they are hard as rock and I have had to resort to a toothpick.

I also clean with toothpip the air inlet on skimmer i also once every few months drill out the inlet with small drillbit cause sometimes toothpic dont work once it builds up to much
