When I first saw it, I assume it was an old plastic bag of some type.. But it was in both baskets..

Turns out it was paint.. I use my garage as a paint both sometimes, and a whole house fan sucks the fumes out the back door of the garage. Unfortunately, this is right over the top of my pool. I have done a ton of painting since the pool as installed, but have never seen this before.
The difference is that this time I was spraying oil based paint.. I assume it collected on the top of the pool water and then moved into the skimmers... It does not look like it made it into the filter (pressure wise), but I won't know until I clean them next in the Spring.
Thanks,
