I really lost track of my pool maintenance these last three weeks and I have a big green bowl out in the back yard. Now we want to close it. It is an AG pool, one of the intex frame pools.

We are thinking of just draining it, as refilling next year doesn't cost us that much, but won't the algae be stuck to the sides still? Do we need to scrub that off now, or will it die out with the freeze?

Should we NOT drain, and treat with bleach?
