Home > CO2 Regulators > Dual Stage

Dual stage regulators adjust the output working pressure in accordance to the input pressure, which means that even if the input pressure increases, the output pressure will remain at the pressure you have set it to, completely negating any possibility of 'end of tank dump'. End of tank dump can occur when the liquid CO2 in the cylinder has been depleted, leaving only gaseous CO2, which increases the output pressure of the cylinder. This increased pressure can result in higher output pressure from the regulator, and therefore a higher volume of CO2 being added to your aquarium than you intended. A dual stage regulator ensures the output pressure from the regulator will remain constant, even if the output pressure from the cylinder increases.

The dual stage regulator also allows easy adjustment of the output pressure, meaning the regulator will meet the needs of any aquarium, and can even supply enough pressure to operate multiple diffusers.

Available with and without a solenoid magnetic valve to enable CO2 dosing at specified intervals and durations.
