Some advice please?

What are you using for an indicator that you need to change your DE? Even in the beginning of the season when opening places the heaviest load on the DE, I change it maybe three times in the first week, then once the next week and that lasts for a month or so. I change it when bumping doesn't bring the psi down as much as it should, and it climbs back up within a couple hours. For my Hayward EC65A I charge it with 4 pounds or so and normal psi is around 12-15. With the factory recommendation of 7 lbs. the pressure runs around 20-25. Bumping happens when either of those numbers rises 5 lbs. or so.

I think you could go somewhat longer between recharges.

I have the same filter as you. When the pool is this dirty I let it run until I can barely see the outlet jets moving (I need a new pressure gauge, haven't got there yet). I bump, repeating process until I see that after I bump I'm shooting a lot of debris back into pool. I usually change the powder after that. I fill a bucket of DE powder that holds around 5 pounds. !2-15 psi is about normal for my filter also.

I love the filter under normal conditions, it just takes a lot of extra work every year when I open the pool up.

Thanks for the input!
