| | Re: Auto High Pressure Co2 setup
I used pH controllers with my Azoo regulators when I first tried pressurized CO2. They worked. Those Azoo needle valves are temperature sensitive and their bubble count varies. The regulator itself is good. A pH controller can keep the CO2 level in check. I ended up putting my pH controllers on timers so that no CO2 was used when the lights are off.
Another option is to get a better needle valve or metering valve and install it on the Azoo regulator. A good valve and a timer should work fine after you get it tuned with a 4 dKH drop checker.
I bought one AP.com regulator and that was my last one from them. I didn't like it. Many people really like AP.com's electronic regulator and some don't like them at all. I wouldn't get one.
I've been using two stage regulators and building them myself. I use metering valves for better control and a timer for the solenoid. That's the way that I would go ... with a pH controller optional.
