    This is really helpful for pool owners. Do you have any tips for the other types of swimming pool filters like DE pool filters?

    This is a nice blog site. What would you recommend as the best way to keep the pool algae free?

  3. Scott says:

    To keep the pool algae free you should make sure the pH is 7.4-7.6. If the pH is off the chlorine will not be as effective. Maintain a 1.0-3.0 ppm level of the proper sanitizer. If you have reoccurring algae use copper algaecide. If you use copper algaecide make sure your chlorine level is not too high to prevent staining.

  4. Excellent tips on backwash a swimmimg pool sand filters. Thanks a lot.

    Should people be OUT of the pool when an operator backwashes a pool?

    My pool turned a nice emerald green because I have overhanging trees above pool. I bought something called Kleen Pool and within three days it was clear. My pool guy had said to drain it since I have a sand filter, but I bought this Kleen Pool stuff and it worked. Whew!

    Karin, backwashing the pool with swimmers is fine. It’s just like running the pump with people swimming.
