    Hayward DE Perflex Tube Filter, can I upgrade to different filter?

    So I bought a house with this pool in December and I have been maintaining it ok I think.

    SLAMing inground pool with DE filter, no recirculate...

    This is my first time opening a pool. I think I closed down too early last fall and therefore opened up my pool to a nice shade of dark green. Never fear! I am a true believer in the TFP SLAM method and have stocked up on liquid chlorine. I went through my first day, lots of sweeping and...
