KH Guardian

[Genvid]

Fellow reefers, who among you uses the KH Guardian? I’ve started experiencing issues with my readings—specifically pH and alkalinity. I suspect it’s time to replace the pH probe, but I haven’t been able to find an original replacement from KH Guardian. Does anyone have experience substituting it with a different pH probe?

@VintageReefer do you have any insights?

I don't see why would you not be able to use any pH probe that will fit that has a BNC connector? pH is pH. I just used a double junction pH probe from amazon and it gives good readings.
