I have the same pool. My pump seemed to be really loosing output after a few days and I can tell since the PSI goes up quite a bit. Couldn't really figure it out since backwashing didn't discharge much dirty water at all, and PSI would go back up shortly after.
I took the top assembly off the sand filter (valve?) and found on top of the sand was a 1/8"-1/4" layer of cottonwood seed, which had almost turned into a thick bed of fabric. After cleaning this out my pump/filter has kept the water moving much better. Looking at getting a skimmer sock or netting to catch some of the cottonwood seed before it gets to the sand filter now. Might be worth checking that if your flow doesn't improve for long.
