The UNS Micro CO₂ Solenoid is the brain of your gas setup, allowing you to completely automate your tank's schedule. Simply plug it into a standard light timer or smart plug, and it will automatically handle your gas injection. It runs incredibly cool, stays completely silent, and ensures your plants get carbon exactly when they need it most.
Note: Designed specifically for direct integration with Ultum Nature Systems micro-scale regulator equipment.

1. Does the UNS Micro Solenoid get hot while running?
No. Thanks to its 12V DC low-voltage transformer, this solenoid consumes minimal power and stays cool to the touch even after running continuously for 8+ hours.
2. Can I connect this solenoid to a smart home plug?
Yes. The power adapter plugs into any standard 110V–220V AC outlet, making it fully compatible with traditional mechanical timers, digital outlet timers, and Wi-Fi smart plugs.
3. When should my solenoid turn CO2 on and off?
We recommend programming your timer to turn the solenoid ON roughly 1 hour before your aquarium lights turn on, and OFF 1 hour before the lights turn off so plants have saturated carbon ready at photoperiod start.

"Finally a solenoid that actually stops CO2. The solenoid that came with my CO2 generator never truly worked. It more or less just slowed the release of CO2 until it finally failed and then didn’t do anything. This unit feels so much better built and actually shuts off the CO2, like a solenoid should. I know the description says it is designed for the UNS regulators but I can say that this 100% works with a CO2 generator. One day I’ll switch to a full UNS system but for now this does the trick."
