I was hoping you'd be closer & I could try to give you some help. We're leaving for vacation Friday & just don't think I'll have the time this week.
You could start a siphon with your vacuum hose & get most of the remaining debris out without using the filter. Not sure how much water you would waste.
The pool doesn't look so bad that it should clog the filter that quickly. My guess is that the fingers themselves need a good cleaning. Hayward used to recommend soaking them in a solution of muriatic acid. I don't remember the concentration but you can check your owner's manual to see if they still recommend that procedure & the concentration.
