We have a 15k gallon AG. We've had it, or a pool like it, for 25 years, and never had a problem until three years ago. We thought we were upgrading the filter to a Sta-Rite PLM100 but it's never worked right. What do we need to buy in order to have a usable pool?
I could go into detail about the PLM100 but basically the pool is muck. Before that we had a PML50DE that kept the pool clean but for brought us to tears when we had to clean it as it never went back together properly, so the PLM100 sounded like a good upgrade. But it's terrible.
We have a Hayward 1.5HP 70GPM motor, if that matters.
