Solenoid to control CO2 scrubber

[FGourdin]

I am thinking of installing an Apex ph controlled CO2 scrubber. CO2 levels in my "tight" house are around 1300 ppm versus 500 outdoors. For logistics reasons can't run current skimmer air intake outdoors. pH in tank 7.8 with Alk= 8.0 Has anyone had experience with a solenoid controlled air intake where valve would open to scrubber say with a ph less than 8.3 and draw room air for ph over 8.3? Can you give some details as to setting it up? Solenoid part number? ( I have looked at the Carr McMaster catalog and find it overwhelming- their customer service won't advise on specific applications!). Any help greatly appreciated.

I bought a solenoid from Amazon, let me find it in my build threads, that worked perfectly with a Apex.

Several years ago, @rkpetersen recommended this to me to control my Co2 scrubber and adding it to my skimmer to help raise my PH. I used a Apex to control it and it worked perfectly.



You can also do the same with a GHL P4, for GHL users.

Did this ball valve get really hot as well ?
