    Every morning I wake up to piles of dead algae that have settled on the bottom. I can brush them toward the drain but the whole pool turns green and the filter never really filters out the dead algae. It's as if it's too fine. Ive tried clarifier hoping that would "plump up" the algae enough...

    my 1st opening-shocking algae-?s about backwashing,rain, etc

    We just bought a house with a pool that sat uncovered for 2 years. After scooping 3 bags of leaves, 1000+ worms and tadpoles, 20+ frogs, 2 turtles, and 1 "God only knows what", I got the pump running and....ok, don't freak out.....took a sample to the pool store and asked them what to do...
