Key Features

• Easy Automated Control: The included solenoid valve takes the guesswork out of CO₂ injection. You can easily automate your CO₂ schedule with a simple timer or smart plug, providing consistent, hands-free control. This means no more worrying about turning your CO₂ on or off, protecting your fish while your plants flourish.
• Reliable Regulator: Our high-quality regulator is the heart of the system, providing stable output pressure to maintain optimal CO₂ flow to your diffuser. The dual gauges give you a clear view of both your cylinder pressure and the output pressure, so you always know when it’s time for a refill and can maintain a consistent flow rate.
• Effortless Monitoring: The included CO₂ drop checker gives you a continuous, at-a-glance view of your CO₂ levels. By monitoring the colour of the liquid in the drop checker, you can easily ensure your aquarium’s CO₂ concentration is within the optimal range for healthy plant growth and a safe environment for your fish.
• Scalable Design: This system is built to grow with you. It’s compatible with a wide range of CO₂ bottles, including those from commercial gas suppliers, allowing for easy upgrades as your planted tank journey evolves and your needs change. This makes it a smart, long-term investment.
• Simple Setup: With clear instructions and a user-friendly design, you can have this professional CO₂ kit for your aquariums up and running in minutes, making it the perfect choice to build your first professional CO₂ setup without the frustration of complicated assembly.

What’s in the Box

Every CO₂ kit for aquariums includes the essentials for success:

• 1 x High-Performance CO₂ Regulator with Solenoid Valve: This robust unit features a solenoid for automated on/off control and dual gauges to monitor pressure, providing the foundation for a safe and effective CO₂ system.
• 1 x CO₂ Diffuser: This high-quality diffuser creates ultra-fine bubbles for maximum CO₂ absorption into the water. This ensures your plants get the nutrients they need to grow strong and healthy, preventing waste and making the most of your gas supply.
• 1 x CO₂ Drop Checker: A vital monitoring tool that provides a continuous visual indication of your CO₂ levels, helping you maintain a balanced and healthy aquarium ecosystem.

• 1 x Step-by-Step Installation Guide: A comprehensive guide to walk you through the entire setup process, even if you’re a complete beginner.

What’s Not Included

• CO₂ Cylinder: You will need to purchase a separate CO₂ cylinder of your chosen size to pair with this regulator system. For example, you can find a suitable option at KegLand.
• Smart Plug / Timer: The included solenoid valve allows for automation, but you will need a separate smart plug or timer to turn your CO₂ flow on and off on a set schedule. You can find options like this TP-Link Tapo Mini Wi-Fi Smart Plug.
