The GLA 3X Series CO2 regulators are one of a kind, there is no match in the entire world! Our expansion X series manifold, allows the user to add manifold blocks with ease, and expand CO2 supply to up to 15 aquariums with three independently controlled solenoids. The 3X series regulators can adapt to your growing needs, allowing you to use one regulator for multiple planted tanks. It's like having the power of 15 CO2 regulators all packed into one installation and for less than half the price. Also, the fact that you only have to invest in and fill/refill one CO2 cylinder makes the ease of this installation and the savings astronomical! We make sure that when you invest in our professional CO2 equipment, you invest in a single regulator that can grow with you and last a lifetime.
