mysterious "webs"

Mik

Reefing newb
I get a disgusting mat of webs whenever i change water. I have a fish tank, not so much a reef tank, so my particulates are always a struggle for me. As i clean things, these mats form. Any clues??
 
Are they white and stringy? Sounds like vermetid snails to me. Do you see a little calcified tube where the string originate from?
