Anyone try adding DE to the sand in their sand filter? If so how do you add it and how much. Did it improve filtration? I'm not getting the filtration I would desire so I am looking into alternatives before completly replacing my Hayward Sand Filter with a comparable DE filter.

Also, anyone try the Zeobrite product in their sand filter? Any Pros or Cons over regular old filter sand?

Thanks in advance .............and looking forward to a happy summer.
