My pool finally cooled down here in upstate NY and i am getting ready to close ..... without even thinking about it i dumped the remainder of a 5 gallon jug of chlorine in and started scooping leaves etc out.
As i am getting it cleared up i decided to check the PH and it is at 8.2.
FC is 14
CC is .5 or less
As a general rule the PH was fairly stable all season and only crept up slightly all summer.
I haven't done much of anything with it since early September other than a gallon of bleach here and there and run the pump once a week.
Can i trust that reading and add MA?
