Aquapro Dual Gauge 12V CO2 Regulator – Precision CO2 Control for Planted Tanks
 
Bring your planted aquarium to life with the Aquapro Dual Gauge 12V CO2 Regulator — the smart, safe, and reliable solution for injecting pressurized CO₂ from standard cylinders into freshwater planted tanks. Designed with aquascapers in mind, this regulator combines accurate monitoring, robust safety features, and easy control so your aquatic plants thrive. 
 
Key Features & Benefits:
 
 Dual Gauge Monitoring
Stay fully informed at a glance — one gauge shows the remaining CO₂ cylinder pressure, and the other displays the working/output pressure you’ve set. This helps you plan refills and fine-tune CO₂ delivery for optimal plant growth. 
 
12V DC Solenoid Valve for Safety & Automation
The integrated 12V DC solenoid valve is safer and more reliable than older high-voltage models. It pairs easily with timers or pH controllers to automate CO₂ dosing (turns on/off with your lights), reducing manual adjustment and improving consistency. 
 
Stable & Consistent CO₂ Output
With high-quality regulation components, the Aquapro regulator delivers stable CO₂ regardless of cylinder pressure changes — preventing sudden bursts that can stress fish or plants. 
 
Precision CO₂ Tuning
A fine-adjustment needle valve lets you dial in the perfect bubble rate for your tank size and lighting — whether you’re running a nano desktop tank or a densely planted showpiece. 
 
Robust Build & Easy Setup
Made for aquarium enthusiasts of all levels, this regulator installs directly onto standard pressurized CO₂ bottles and works with common aquarium tubing and diffuser systems. 
 
Whether you’re a beginner looking to start CO₂ injection with confidence, or an experienced aquascaper demanding precise control, the Aquapro Dual Gauge 12V CO₂ Regulator delivers the performance, safety, and peace of mind you need for lush, healthy planted tanks.
