I did my monthly calibration of my PH meters. ATC meter was off by .1 and I turned the screw to calibrate it.
Tested my PH. It was high as I expected.
Added about 1/3 a gallon of MA.
Meters are ATC pH Meter and Waterproof Pocket pH Tester with 0.1 Resolution - pHep - HI98107 - Hanna Instruments
Note that PH Meters are usable at high FC levels.
If you get a PH meter you need to shake it in the water to get air bubbles off the probe until the reading stabilizes.
