If the water is in an airtight container with no "air space," then
theyre would ge no where for the CO2 (that's in the water) to go-even
after 45 minutes.
I have used the AP pH test solution and never had a problem. But that
doesn't mean it couldn't happen and isn't worth checking. For less
than the cost of the drive, you could get a more expensive pH kit and
double check your measurements. Yes, you'd have to drive to get the
new solution but only once and then you'd be able to do many tests
withot driving back to the store -- or you could order on-line. Do
you trust you KH and GH test solutions?
