Good morning,

Monday evening my pump was running and was quite loud. I had normal pressure on the pressure gauge on the filter and water was being circulated. On Tuesday, pump motor was running, no pressure on the pressure gauge and water was not being circulated. Once the pump was taken apart, the impeller was broken. I ordered the part and the pump was reassembled last night by 1700.

(normal pump time is 9hours/day from 1000-1700 with SWG about 30% right now)

Prior to the pump failing my numbers were as follows
pH-7.5
FC-9 (I was just coming off a SLAM due to sneaky algae behind the light)
CC-0
TC-0
TA-70
CYA -50
salt 3100

I retested last night - numbers are as follows
pH -7.2
FC -5
CC-0
TC-5
TA-90
CYA - 50
salt 3100

I have had the pump running since I reconnected it. I have vacuumed the pool and brushed all sides and bottom. Water looks clear. No evidence of green. Not cloudy. passed the OCLT last night
My questions are as follows:
Why the change in pH and TA and should I correct it?
Any reason to SLAM??

TYIA!!

No reason to follow the SLAM Process with those conditions.

Hard to say on pH and TA. Neither moved all that much. Both are fine and no adjustment needed.

Thank you! That was my thought and greatly appreciate the validation.
