Hydros co2 solenoid for nano skimmer with scrubber

[rustin40]

Trying to use the Hydros co2 solenoid on drive port to open fresh air on my nano skimmer with co2 scrubber based on ph but struggling to get it to work. Any advice?

This will open solenoid at 8.4, remain on/open until pH drops below 8.35, close and remain off until pH rises above 8.4 again. And repeat...

Thanks a ton! I guess I was just overcomplicating it. Just heard my solenoid kick on as soon as it uploaded it to controller. Appreciate you help!
