That's good. Your filter is catching stuff and you're removing it on a timely basis. This is guesswork, but I believe you will see small improvements each day for a while and then, suddenly the sparkle will be back!!Pressure gauge runs at 18 after backwash and rinse and I backwash at 22, it has been every other day or so.
