The pool store is using a titration method for the TA and CH tests..no strips for any test. Then they just input the number into a computer, and I get a printout. My TA Wal Mart test goes from blue to clear not green to red. Then you multiply # of drops by 10 to get ppm. I'll have to see if there is another store around here that will do it.

Hopefully Ben's kit arrives quickly...and my husband stops bugging me about adding the Calcium.
