CURRENTLY SOLD OUT
Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in pH Test Strips
Each strip has two color pads ..... it is unclear to me if just one, or both have to match the guide on the box. Two never match and sometimes none match, so I'm assuming that if just one pad is close to something on the color chart, it is what your pH reading is. But I'm still unsure ! It would be nice if the instructions were more detailed / specific
