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.
