The CO2Art PRO SE Series Dual-Stage CO₂ Regulator is a high-performance control system designed for planted aquariums—ideal for freshwater and marine setups alike. With its dual-stage pressure reduction, integrated solenoid valve and precision needle valve with bubble counter, this regulator delivers reliable, safe CO₂ dosing with automation capability.
Key Features:
Dual-stage pressure regulator ensures stable output pressure and prevents “end-tank dump” when the cylinder pressure drops.
Built-in 12 V DC solenoid valve and universal power adapter (100-240 V) — allows automatic control via timer or pH controller.
Adjustable working pressure up to ±40 PSI (≈3 bar), suitable for both tropical and marine aquariums. Included bubble counter with check-valve and needle valve for fine flow control.
Dual gauges: one for cylinder pressure (tank volume) and one for working/flow pressure.
Thread connections compatible with multiple standards (BS341 / DIN477 / W21.8 / CGA320) allowing diverse cylinder compatibility.
Usage & Tips:
Always attach regulator to the CO₂ cylinder using correct thread type and ensure washer seal is intact.
After filling the tubing and system, connect the solenoid to a timer set for your light-cycle so CO₂ is only active while the lights are on.
Adjust bubble count gradually; typical starting point is 1-2 bubbles per second, then test and refine using a drop checker for ppm.
Monitor the cylinder gauge; when it starts to fall rapidly, the inside liquid CO₂ has drained and slower drift can follow.
