Add a CO₂ source to your planted aquarium setup

✅ Choose a one- or two-litre bottle for your setup.

✅ Monitor bottle pressure on the fitted gauge.

✅ View gas flow through the bubble counter.

✅ Adjust output using the control valve.

✅ Use the supplied solenoid valve for electrically controlled gas flow.

The cylinder is 304 stainless steel. R01 uses an internal-thread aluminium-alloy valve, X01 an external-thread aluminium-alloy valve, and X01-A a stainless steel valve. R20 options use a stainless steel dual-gauge valve.

The reaction uses citric acid, baking soda and water. Quantities differ by model, so follow the selected bottle’s instructions and do not overfill, invert or disassemble a pressurised bottle.

The solenoid can be paired with a separately supplied timer for scheduled switching.

Choose the option that fits your project and add it to your setup.
