2nd PH probe

[Incaico]

Are there any benefits of having a second Ph probe in your setup?

 

[Mr. Brooks]

PH probes go bad over time, so a second probe could tell you when one of them is on its way out. You could also use a second probe on a calcium reactor or kalk reactor.

I don't think there is any major benefit.
you are supposed to calibrate your ph probe periodically. you know it is time to replace if it cannot hold the calibration. (i.e. after calibration, if you dip the probe back into say the 7 solution and the reading is not 7)

Depends on your 'setup'. I have one pH probe that measures the tank and a second that measures my CaRx.
