The Ultum Nature Systems Mini CO2 Regulator is the perfect hassle-free and budget-friendly solution for those looking to inject CO2 into a planted aquarium tank. This regulator comes with everything you'll need to attach onto a standard (CGA-320 threaded) 2.5lb - 20lb CO2 cylinder without worry about potential gas leakage as long as your wrench arm is strong. In addition, this is quite possibly the lowest priced and smallest professional-grade CO2 regulator available. This means no additional clutter from a clunky regulator that takes up precious cabinet space.
Designed with safety and precision in mind, the Precision SMC Needle Valve allows the user to adjust CO2 output little by little accurately. With the help of the locking mechanism, there's no need to worry about accidental adjustment. Just set it, lock it, and forget it.
No matter what type of planted aquarium setup you have, we recommend CO2 injection for better aquarium plant growth.
