Happy Fourth of July! I was hoping for some confirmation that the pool is ok to swim in today.... I am new at this, have been reading Pool School and have started testing using a Taylor 2006. We did not use the pool in about 5 days due to rainy weather.
Here are the results of the tests from 5 days ago and today:
Test 5 days ago Today
FC 7.5 12
PH 7 7
TA 90 90
CH 170 150
CYA 95 90 - 95 (went down a little bit)
I checked out the Chlorine/CYA chart in Pool School and the chart does not go up high enough to account for a 90 - 95 CYA
My FC is much higher at 12 today - Is it ok to swim in? Is my Ph too low?
The solar cover was on for 5 days, I took it off this morning before I tested but it is not that sunny today.
