Using TF100 test kit from last year i was getting CYA reading of around 40, when i ran out of reagents i had my water tested at Leslie's and got a CYA reading of 30. I ordered new reagents for the test kit and the first test with the reagents was CYA of 65.
All readings were within 5 days.
Should i assume 65 is the right number?
Did no draining of pool or added any cherms other than bleach.
