    I thought I was dealing with algae. Not sure substance on bottom of pool.

    My pool had blk looking substance on the bottom I vacuum it out with cordless vac. Pool was crystal clear. turned filter off for a day nothing on bottom of pool. When I turn filter back on within a hour substance back on bottom of pool. Can this be a cracked finger or what I was being told if it was algae it would have settled when I turned the filter off. Help pleaseee.
    My pool is 28 ft above ground round. Hayward pump/filter

    Turn off pump for an hour. Hold sock over return while someone turns on the pump. If you get sand, you know where it is coming from.
