Brown goop in skimmer?

I agree that it's pollen or plant debris. I have the same issues - my pool is under or very near 5 oak trees. I have it all the time, every year. I clean my sock out every morning and evening.

Pollen here, too, along with cicadas. Those things are huge and I'm finding quite a few of them in my pool. YUCK!!

Pollen. Looks like yellow spackle here. It should end in a couple of weeks. I have to clean it out a couple of times a day.
