1. Can I use the UNS Micro Regulator Kit with a standard 5LB CGA320 CO2 cylinder?
No. The UNS Micro Regulator is designed specifically for 95g UNS Disposable CO2 Cartridge. For full-size CGA320 cylinders, we recommend using UNS Mini Dual Stage Regulator or UNS Pro Dual Stage Regulator.
2. Does the solenoid require a separate timer to automate daily dosing?
Yes. The electronic solenoid plugs into any standard wall outlet or smart plug timer, allowing you to synchronize your CO2 output with your photoperiod.
3. Is a check valve required with this setup?
The included UNS Micro Bubble Counter features a built-in check valve to prevent back siphoning, though adding an inline check valve near your diffuser is always recommended for extra safety.

"I'm not super handy, so I was a little intimidated going in with this kind of setup but it's literally screw everything together and go. Fits right inside my cupboard where I needed it. No loose parts. Works perfectly! I like that you can buy an adapter to use it on a paintball cannister if you need, means I won't have to change my whole setup if I feel I need to upsize."
"This regulator is decent nothing crazy but nothing bad. The thread pitch seems to be 5/8 UNF so adapters are readily available for paintball tanks and smaller 3/8 UNF fittings. DOES NOT WORK WITH 90 GRAM PAINTBALL CARTS. I tried and ended up with 180 grams wasted. UNS carts should work as well as some 74 gram carts designed for beer. Anything 5/8 UNF."
