I only wish. I check and empty them daily. Nothing more than a few blades of grass. Even though my pressure hasn't increased on my filter, I'm going to backwash and add a cup of DE for good measure. I read here on the forum you don't grow algae in a properly maintained pool, and therefore don't need to brush the walls, but I think I'm going to do that also even though I don't feel anything on them. It's a difficult job from outside an above ground pool but I don't think I should get in the pool at 14ppm FC.

Thanks for everyone's suggestions...keep 'em coming!
