My test results vs. Pool Store...now what??

[waterbear]

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.
This is interferance from high chlorine levels. Same thing can happen with the Taylor kits or Ben's kit. Your chlorine levels must be higher than you are posting when you are doing the test! One of the indicators in the TA indicator solution is getting bleached out. The color is actually going from blue to very pale yellow. (I am assuming you have the Walmart Aquachem 6 way kit, some walmarts sell the HTH 5 way kit, I am not familair with that one but I believe it uses the same reagents as the Taylor kit)
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.

Hope this is helpful.
