Is it best to drain water from bottom of pool or from top level since it seems the extra 1.5 feet of rain over the last month is not changing my cya very much. I see it around 40 something but pool stores says 50 to 61 from 4 different testing sites. Old eys makes it hard to tell when black dot disappears. thanks
