    Closing: Where do I dispose of the sand AND, do I backwash?

    OK, I've had my new ABG pool up since June. I use the BBB and have had no issues at ALL. In fact, I did not backwash my filter all season. The pressure quage never came close to indicating it was needed and my pool sparkled with an occasional vacuum and regular chlorine maintenance.

    Time to close.

    1 - I should remove the sand and clean out the filter container, correct? Any reason to keep the sand in there? I'm guessing there's no need to backwash since I'm emptying the sand out.

    2 - where do I dispose of the sand? I don't need it anywhere on my property.

    3 - any recommendations on the brand, and store, for buying a mesh cover?

    Most everyone lets the sand remain. It's very reusable and, in your particular case, should be sparkling clean and ready for next season.

    Too funny! I was just cutting the grass and thinking, "why can't I just reuse it!"

    Should I backwash just for hahas??

    I see no reason. I would certainly suggest it in the Spring but let the psi guage be your guide.

    Leave the sand in the filter. I would replace the sand when you replace the filter (hopefully many years from now). I would reccomend backwashing before closing the pool just incase your guage is wrong. Backwashing will help ensure that the filter drains properly when the drain cap is removed.

    Thanks guys. The water has been crystal lear all summer, so I'm betting the gauge is ok. But I do agree with backwashing end of the season, especially since I'm getting more debris in the pool now, then I did during the summer. Fall is coming early my friends ; ) But I want to keep the pool open at least until November, though not for swimming. Just to keep the water clear as long as I can.

    thanks again
