This set suits keepers of planted aquariums who want to supply CO2 from a single kit and control it automatically. The solenoid valve can be connected to a timer or pH controller, so CO2 dosing can be switched on and off without manual adjustment.
Why it matters
- The solenoid valve connects to a timer or pH controller, which switches CO2 on and off automatically. The vendor notes this is useful at night, when plants take up less carbon and pH tends to drop.
- Two gauges show the pressure inside the cylinder and the working pressure after the regulator, so gas consumption and pressure reduction can be checked at a glance.
- The regulator includes a bubble counter, a precision valve and a check valve, and is made from a metal alloy.
- The glass diffuser has a ceramic sinter and releases gas across its whole surface, which the vendor states improves CO2 dissolution and reduces losses.

What it works with
The set is intended for planted freshwater aquariums that are dosed with CO2. The Drop Checker, mounted in the tank, shows CO2 levels through a colour change, which helps in setting the bubble rate. Cylinder lifespan depends on tank size and dosing, as noted above.

Frequently asked questions
The kit includes everything needed to get the system running, including a wrench for attaching the regulator to the cylinder. The regulator has a built-in gasket, so you don't need extra thread sealant. The regulator also includes a bubble counter, a precision valve, a check valve and a solenoid valve.
The solenoid valve is designed to connect to a timer or a pH controller, which turns the CO2 supply on and off automatically. The supplier recommends this setup mainly for nighttime, when plants don't absorb carbon dioxide and pH tends to drop.
The total height of the cylinder with the regulator mounted is 59 cm. Measure the space where you plan to place it before ordering.
Depending on tank size and the amount of gas dosed, the cylinder lasts from about 3 months in very large aquariums to up to 12 months in small ones.
The warranty period is 24 months.
