Hello. I recently upgraded my 1 hp Hayward superpump with a variable speed Pentair 342001, 1.5 hp. I have an 18x36 around 25,000 gallon pool. My current filter is a Hayward perflex ec65, which I now see has a flow rating of 67 gpm. Now looking at this pump which has a flow rate over 100, I’m thinking I’m oversized. My pressure has been running over 20 so far which is much higher than it did previously. I’m guessing this filter isn’t large enough? Any filters that you could recommend I replace it with? Thank you.
