CO2 Products by Type: Aquarium CO2 Regulators, Controllers & Solenoid Valves

We carry CO2 regulators and controllers from ista and the Milwaukee Instruments MA957 CO2 Regulator w/ an integrated Solenoid Valve and Bubble Counter. The CO2 regulator is what drops the pressure from inside the CO2 tank down to a useable level and holds it there. If you were to open the valve on top of a CO2 tank without a regulator, then a huge gust of gas would rush out and the tank would soon empty itself. To stop this we use a regulator to set the pressure. Regulators have a valve, and either one or two gauges. The valve allows you to set the outgoing pressure.
