I wasn't sure where to post this as it could potentially fit into several different categories. Feel free to move it if there's a better place...
Due to winter rains and snows, I've had to pump about 12 inches of water out of my pool so far. We had nice weather this past weekend, so while I had my cover peeled back to drain some water, I decided to break out the trusty test kit (I was going through testing withdrawal ).
Because of the rain water, my CSI is way out of whack now, mainly because my TA and CH have dropped considerably.
My current numbers are:
FC = .6 (was quite surprised by this...I closed 2 months ago!)
CC = .4
PH = 7.5
TA = 60
CH = 150
CYA = 40
Temp = ~40 (I'm guessing because I didn't have a thermometer in the water, but there was a thin sheet of ice on the top.)
According to the PoolCalculator, my CSI is -0.87. Should I add some TA and CH and mix with my sump pump, or is it ok to leave it alone until I open?
