Not sure this qualifies for The Deep End... but it occurs in the deep end so...
Tomorrow gonna vac the pool but today brushed it. Nothing came off the walls but a fine wispy gray cloud appeared momentarily when brushing the bottom.
is this dirt or live algae or dead algae or all three or none of the above?
is it more effective to brush this stuff up and let it pass thru the deep drain and fllter out or more effective to vac this stuff up?
