Quick question on reading the Taylor PH test.
For the last two weeks every time I test for PH, as soon as I add the drops and shake it, the color immediately turns purple which would be a PH around 8.0. Then I wait for 10 to 20 seconds and the color settles in at 7.8. My question is should I be using the immediate reading of 8.0 or is it ok to wait the 20 seconds and use the 7.8 measurement?
