This is one of the reasons I’ve been avoiding using a carx. It’s such a crucial part of the life support of the tank so if the probe drifts it can be detrimental. I don’t know if I want to commit to monthly calibration. How much do you typically have to adjust it each month?Yes, using a pH probe that gets calibrated every month.

When I was monitoring the dt I’d be lucky if I recalibrated every 6 months but then it didn’t really matter.
Yeah, I would never be able to trust controlling one off a ph probe. Just wouldn't be able to sleep.The way I have it setup, it is not really controlled by the pH. If the inflow and injection of the CO2 is constant, the pH will be maintained at that level. The only way it would change is if the either of those parameters change or the pH of the tank changes dramatically. I do not have the Apex control the pH. Only control it has is on the solenoid if it drops drastically (set to turn off when below 6.4).
The key factors in a setup like this is consistency and reliability of the input and the CO2 injection. Hence the Masterflex and the custom CO2 reg with metering valve.
The pH is only there for monitoring. If I see a drastic change, something is wrong.
and your ph reading is at 6.5-6.8? guess i need to stick my ph probe in this weekend.
I would forget the ph probe. Nice metering valve is all you need. I think I have a bunch of hoke valves if anyone needs one. Got them a long time ago very cheap.
