I took the cover off yesterday and the water was dark murky green (blue pebble), and there was a layer of yellow silt on the steps.

Thanks tree.....thanks.

I also noticed that the DE filter was ready for cleaning, so I cleaned it out. Yellow mustard-like substance (DE and pollen) oozed out, very gross.

We normally run 1ppm FC, so I shocked it and trimmed the pH. The pool is still green (hot tub is clear as it's even been).

Pool store gave me what sounded like a coagulant to help clean the pollen out.

Any other tricks for dealing with oak pollen?

Skimmer socks or cheap nylon stockings usually catch it before it get to the filter.

Thanks, I ordered some.
