I am helping a friend set himself up for self pool maintenance. Ran the tests on his pool last night.
FC 3.5
CC 0.5
CYA 90
He has an odd sized pool. Our initial estimate of pool size was 15K gallons, and we added in 3 gallons of Chlorox. FC was 21.5 after 2 hours indicating we overestimated the pool size.
Can I use the change in FC levels to estimate his pool size (should be ~10K gallons based on the change in FC assuming no algae given low CC levels)?
The test was done in the evening so little Chlorine should be lost to the sun. The only piece I am not sure how to incorporate is the high CYA.
Thoughts?
