white algae

[Lisasalgae]

I have clumps of white, grayish stuff on bottom of my above-ground pool. It is "fluffy" and disperses when brushed and re-settles. It is not on the wall. It started last summer and survived the winter close-up. We've spent hundreds of dollars for chemicals and nothing works. Local pool store says it is "algae". Otherwise, the water is crystal clear except for the white clumps on the bottom. The liner is two years old and has no stains. PH is good.

What you see is dead algae. Just vacuum it up and you'll all set. Your algaecide and/or shock is working!
