Green Bubbles CO₂ Generator – CO₂ kit with solenoid valve

This complete CO2 kit suits aquarists setting up or upgrading a planted tank in the 20 to 200 L range. It replaces a set of separate, loosely connected components with one assembly that includes pressure reduction, dosing control, flow counting and a timer-compatible solenoid valve.

Why it matters

• The regulator, solenoid valve, precision needle valve, bubble counter and check valve are mounted together, so no individual part hangs loose on the tubing.
• The solenoid valve connects to a timer, so CO2 switches on and off automatically for day and night cycles.
• The precision needle valve is adjusted with a single knob, and the bubble counter lets you read the dose in bubbles per second.
• A filter with a dense sediment insert and activated carbon sits in the line to keep impurities away from the regulator.

What it works with

The kit fits planted freshwater aquariums across the full 20 to 200 L range, and the manufacturer specifies two bubbles per second as a typical dose for roughly 100 L with dense planting. The two-component mixtures, once combined with water, produce food-grade CO2 steadily, so the set runs without a separate pressurised cylinder refill. It requires a 230 V socket for the solenoid valve and a timer if you want fully automatic operation.
