I haven't had a need to back wash my DE filter for over 2 months now and the sight glass on the multi-port grew all kinds of different things in there. It does have some distinct yellow spots:
So, I'm curious if this shows that the area that I'm in have some mustard algae spores around? The pool is all good, it's just the sight glass.
