This set suits planted aquarium keepers who want to dose CO2 from a single kit instead of assembling regulator, valve and diffuser separately. The integrated solenoid valve lets the supply be switched on and off automatically, which helps keep CO2 stable overnight, when plants stop consuming it and pH tends to drop.
Why it matters
- The regulator has a built-in bubble counter, precision needle valve, check valve and solenoid valve, so the main CO2 components are already combined.
- Two gauges show the pressure inside the cylinder and the working pressure after reduction, which makes it possible to estimate gas consumption and check the reduction level.
- The solenoid valve is designed to connect to a timer or pH controller for automatic switching of CO2 supply.
- A glass diffuser with ceramic sinter releases gas across its whole surface, and a drop checker placed in the tank shows CO2 levels through a color change.

What it works with
The kit is designed for planted freshwater aquariums that require controlled CO2 dosing. The 2 L cylinder and 48 cm total height make it a compact option for smaller setups, while the solenoid valve allows it to run alongside a timer or pH controller. The cylinder duration depends on tank size and gas dose, so a small tank will go through a cylinder far more slowly than a large one.

Frequently asked questions
With the regulator mounted, the 2 L cylinder setup is 48 cm tall. The total height for a 5 L cylinder with the regulator is 59 cm.
Duration depends on tank size and how much gas is dosed. According to the manufacturer, a cylinder lasts from about 3 months in very large tanks up to about 12 months in small ones.
No. The regulator has a built-in gasket, so no additional sealing is needed. A wrench for tightening the regulator onto the cylinder is included in the box.
Yes. The solenoid valve switches CO2 on and off automatically when it is connected to a timer or a pH controller, which helps keep CO2 at a safe level overnight.
The included glass drop checker sits in the tank and continuously shows the CO2 level in the water through its color change.
