Color Extended Manifold CO2 Regulator

Size CGA320 W21.8

Ships From United States

Achieve precise, stable CO2 delivery for your aquarium with a dual‑stage regulator that guards against end‑of‑tank dumps and delivers steady gas flow.

Dual‑stage design maintains constant output, with a built‑in safety valve and adjustable pressure up to 65 PSI, so you protect your aquarium from CO2 shocks.
Expandable manifold blocks let you add or remove lines quickly; each block includes a high‑precision needle valve and a bubble counter with a check valve, keeping your setup flexible.
DC 12V solenoid valve delivers low power operation (≈2.5 W) that keeps you in control with timers and quiet cycling.
Rugged metal construction with CGA320 compatibility and included installation tools plus an extra manifold; note: not for paintball tanks; when power is off, releasing trapped gas may take 3–5 minutes.

Why Choose Dual Stage Over Single Stage Regulator?

As the compressed CO2 gas inside the cylinder is running low (pressure is low), a single stage regulator has a much higher risk of letting off huge volume of CO2 gas. This is called end of tank dump, the CO2 disaster that can kill all your fish in the aquarium.

A regulator with two-stage regulates the pressure better and maintains stable CO2 output. This eliminates the sudden CO2 dump (can happen due to low pressure) called end-of-tank-dump (EoTD) catastrophe.

The Pro Series dual stage CO2 regulator is your best choice for injecting CO2 to your aquarium

Pro Series has dual stage structure and safety built-in plus adjustable output pressure
Expandable manifold blocks with integrated high precision needle valves and bubble counters
DC 12V solenoid valve is high Performance and uses less power

Dual stage structure with adjustable output pressure and safety valve

Dual stage design, stable output pressure, and eliminates "end of tank dump"
Pressure knob is adjustable from 0-65 PSI depends on your needs
Dual gauge indicates tank volume and working pressure
Safety valve built in. When the pressure is exceeding 100 PSI, the valve will automatically release the pressure

Expandable manifold blocks- each comes with integrated high precision needle valve and bubble counter

With easy installation you can add or remove additional blocks as needed
High precision integrated needle valve. Flowrate can be adjusted to as low as 0.3bps
Bubble counter has check valve built in to prevent water from backflowing into the regulator
Fits standard 4/6 mm (3/16" inner diameter) CO2 proof tubing

*Fill the bubble counter with fresh water only. DON'T use oil or salty water*

DC 12V solenoid valve, high Performance, cool operating temperature

This solenoid is designed to work with an automatic timer
DC 12V solenoid is safe and is much more stable than the AC solenoid
Low power consumption: 2.5 watts only. keeps the solenoid cool to the touch during operation
Re-designed solenoid opens and closes smoothly. No more overheating and buzzing sound

The PRO Series Dual Stage Regulator

Safe 12V DC Integrated Solenoid Valve
Adjustable working pressure up to 65 PSI
Made of solid metal material
High precision needle valve
Bubble counter with built-in check valve
Expandable manifold block
Easy to install – installation tools are included

North American CGA320 fitting only (not compatible with paintball tanks)
1 extra manifold is included (1 is already attached on the regulator). Additional manifold can be purchased
Take 3-5mins to release the gas trapped inside the regulator when the solenoid is powered off
While the regulator is powered off, the low-pressure gauge may not show 0 because gas is still trapped inside the regulator. This is normal
