I started my pool up about a month ago and have had great test results using a 4 year old TF-100 kit.
FC=8
PH=7.2
TA=110
CYA=60
Started running out of test chemicals so ordered a new refill kit and received it last week. This past week we have gotten quite a bit of rain and had to drain about 4" off this past week. Today I used the new test kit and the TA is now showing 250. Does the TA test chemicals expire over time? Dont know how the TA got so high over the past week.
