Came home from work and tank was super cloudy. Look at my pump and saw this..? what the heck? I'm doing a water change tonight (wednesday nights) I pulled my pump out and am running it in some vinefav water it needed to be cleaned anyways. But what the heck is this?

I took it out right after that picture. And threw it away then dropped the pumps in vinegar. It was white and a blob of goo. When I touched it it broke apart but was still slimy
