last year i closed my pool with CYA of ~40.
this year i opened and every day i lost all of the chlorine i was adding.
checked CYA and it was 0 !
slowly brought it up again using old pucks.
until the CYA was above 20, i lost every bit of chlorine i added during the day
i've just noticed a 2-3 psi drop on the pressure gauge.
i made sure the the skimmers and pump basket were clean. no change.
when the pump basket was out i reached in and didnt find any garbage.
might it be the pump motor is going ?
thanks
