My pump was not working for two weeks while I waited for a warranty repair. I was able to keep the FC at or above 7 (CYA of 80) and the water stayed clear for about the first week. After that, the water began to turn green. I upped the FC to well above 10 and the green never really got worse. The repair was completed on Friday so I have been running the pump ever since. It was amazing how clear/clean the pool looked after only running over night.
I tested the water yesterday and got the following results:
FC - 17.5
TA - 110
CH - 290
CYA - 80
PH - ? The reading showed over 8, but I understand that it is not accurate with FC over 10.
Today, the FC was 13.5 and CC was less than .5. Again, the PH read high.
Question is.... should I give it the rest of the day for the FC to get below 10 so I can get an accurate PH? I want to bring the FC to SLAM to make sure there isn't anything hanging around.
