Palys closed

Hi guys can anyone tell me what these web like stuff is? Wasn't affecting anything before but now the polyps remain closed

I'm thinking that those could by hydroids. Your picture is pretty blurry but I can see a paly in the back of the colony pretty open and healthy. Brush off the white web like things you are describing and see if that changes anything. Hydroids can agitate zoas/palys when there are a lot of em.

Thank you. Wasn't sure if it was something a pest was leaving behind
