The CO2Art Pro-Elite Series V2 is the brand's most advanced dual-stage aquarium CO2 regulator, with an integrated 12V DC solenoid valve, a high-precision needle valve, and dual stainless steel gauges that monitor both cylinder and working pressure. The dual-stage design minimizes the rise in output pressure as the cylinder empties and helps prevent end-of-tank dump, while an extendable manifold block can feed multiple diffusers from one regulator. This listing represents the North America CGA320 configuration paired with a solenoid for use with an inline atomizer or reactor.
