  1. When I vacuum with my sand pump the algae just blows back in the pool thru the jet What can I do? I lose so much water if I turn the pump on waste.

    Dead algae is on floor of my pool. I have a cartridge filter so I can’t back flush and when vacuuming it blows back into my pool. How can I get algae off the floor?

    1. Thanks Kathi Kassinger.
      Begin vacuuming as you normally would, and if you see dirt or dead algae is bypassing your filter and blowing back into the pool, your filter needs attention before you can proceed. Try cleaning the cartridge (you may need to do this several times). If the debris is still bypassing the filter and blowing back into the pool you need a repair to the filter itself – by a service professional.

  3. Also. Its not good to let the dead algae get into your filter cartridge. What I do after I shock and dead algae accumulates on bottom of pool ? I create a siphon with garden hose or bigger pool hose and suck out the algae along with water. You could catch the siphon water in a bucket then filter it with a pillow case. Sounds Crazy but if you don’t want to waste you water , it helps

    1. Thanks Emily
      Vacuum is the best way to remove the death algea. After shocking, you should vacuum the pool water properly. Siphon is not the right way to remove dead algea. Moreover, it wastes water. If you do it, don’t allow to catch that water. Because it may have a chance to rebirth algea in your pool.
