filter appears to be clogging

If the filter pressure rises, flow rate drops and then after backwashing, it returns to normal, that is just the filter filtering something out of the water. Are you sure you don't have an algae bloom?

my skimmer basket was stuffed full of pine needles last night. That tree has to go!
Water is clear, quick check with the oto yellow drops showed fc at least 5. So no apparent algae.

I will keep backwashing and rinsing. I am having trouble getting vacuum seal to clean the bottom. My old attachment is slightly smaller than my new skimmer, and the new attachment that was included with the new skimmer does not have a rubber seal. I will have to get some skimmer socks as well.

Are you getting a lot of pine needles out of the backwash? If not, what is coming out?

I have an in ground drain for backwash, so I never see it. But I think I would see pine needles in the pump basket first, which I do not. I will keep messing with backwash and rinse. Thanks.
