CO2 scrubber setup?

[afboundguy]

Has anyone used Hydros to control a CO2 scrubber hooked up to their skimmer? I was thinking of having two solenoids with one hooked up to the scrubber and one to "fresh" room air and depending on pH it would draw from scrubber if low and room air if in range? I was thinking I could hook them up to an outlet and control them that way which I have done with my DIY RODI auto-fill and auto-flush setup.

Along those lines does anyone think one of the water sensors could be used to automatically fill the scrubber when water in it gets too low? Currently using a BRS reactor for the scrubber so not sure I could even fit anything in there and not sure if there is a DIY option that could fit inside the plastic container?

Yes. You can use HYDROS outlets to switch two solenoids so one pulls scrubber air when pH is low and the other pulls room air when in range. The water sensors won’t reliably detect CO₂ scrubber level, so auto-filling inside that reactor isn’t practical. A separate float switch in an external reservoir would work better.

I might try and figure out a way to manually add a little bit of water on a set schedule once I figure out how long it takes for the small amount of water to dry up.

I might suggest a ball valve or pinch valve because most solenoids aren't designed to be on for an extended period of time.
