I got this ph pen and it's showing my ph is very high all of a sudden. 8.8-8.9. Been working fine since day 1. The past month or so it's been high.
I'm going to get another new calibration solution to recalibrate it.
Is this any good to test tanks with?
Thinking about trying to ph pen from Hanna
I know I should just get an apex! Shush.
