I broke my 2nd PH tester

Mine is unbreakable and never needs calibration.

Need budget meters

Here is my morning PH test of my DWC nutrient, and it’s too high at 6.2 to 6.3, so I’ll add a few mls of PH down. I have had this bottle for over a year and done at least 500 tests, and it’s still half full. [ph]
