Pro Aquarium CO₂ System with Dual Gauge Regulator - Aquapro

Pro Aquarium CO₂ System by Aquapro is a premium complete CO₂ kit designed for serious planted aquarium enthusiasts who require maximum precision, stability and reliability. Featuring dual gauges, an integrated solenoid and precision bubble counter, it allows highly accurate control of CO2 delivery for improved plant growth, stronger colouration and healthier aquarium conditions.

Built from machined anodised aluminium, the Pro CO₂ System is both lightweight and highly durable, with a premium finish designed to withstand long-term use. The robust construction, high quality internal components and reliable screw-fit assembly ensure consistent performance with minimal maintenance. Precision control dials on both the solenoid and bubble counter allow for extremely fine adjustment of CO₂ output, making it easier to maintain stable and repeatable injection rates.

The dual gauge design allows you to monitor both working pressure and remaining cylinder pressure at a glance, helping you keep track of CO₂ levels more accurately and avoid unexpected depletion. The integrated solenoid enables automatic CO₂ shutoff when connected to a timer, allowing CO₂ injection to run only during lighting hours for greater efficiency and reduced waste.

Compatible with standard W21.8 threaded CO₂ canisters.

Included:

1 x Pro Dual Gauge Regulator & Solenoid Valve

1 x Bubble Counter

1. Assemble by screwing the bubble counter onto the solenoid outlet.

2. Once assembled, mount the complete regulator unit securely onto the CO₂ canister.

3. Ensure the regulator outlet flow dial is fully turned off before opening the canister.

4. Slowly open the CO₂ canister valve to pressurise the system.

5. Connect power and turn on solenoid. Gradually open the regulator flow dial to allow CO₂ to begin flowing.

6. Adjust the output using the control dial and monitor the bubble counter to achieve the desired bubbles per minute.

Always monitor CO₂ levels carefully when first setting up the system or when changing to a new canister. Stable CO₂ levels are important for both plant health and livestock safety. Pressurised CO₂ systems provide precise and consistent carbon supplementation for planted aquariums.
