Left it to run overnight. 9 AM water still looks like milk. Checked Chlorine level and it was at .5 so I added another bottle 96 oz of bleach. PH is at 7.2.

How come PH is staying at 7.2 and doesn't go down at all? I thought that it would go way down.

Should I try to backwash my filter? Pressure was at 35 this morning.

Thanks,
B.
