What is the hard white squiggley stuff that gets all over everything? Looks like worm casings of some kind but I never see any worn or evidence of life. It gets all over my equipment & glass, but is harder to get off equipment.

It is worm casings. Probably serpulids. http://reefkeeping.com/issues/2003-05/rs/index.php

These are tiny, and they are only in my sump - not in fuge or DT. They weren't shown in the article, but I guess I can assume they are some kind of worm and not detrimental.
