Precise CO2 dosing - Integrated fine needle valve gives full control over the amount of CO2. - Includes a high-quality bubble counter to adjust the number of bubbles per minute individually. - Enables optimal CO2 supply for plants, supporting strong growth. Reliable monitoring and planning - Two precise high-performance pressure gauges allow easy and safe monitoring of CO2 pressure in the bottle and at the outlet. - Bottle pressure indicates when CO2 is used up, enabling optimal planning of the next filling and helping to avoid CO2-free periods. - Spout pressure is used to control the optimal flow rate into the aquarium. Specifications - Colour: silver - Material: ABS Use scenarios - For densely planted freshwater aquariums, set the desired bubble rate and monitor pressures to maintain stable CO2 dosing and healthy plant growth. - When planning refills, use bottle pressure readings to determine the next filling time and prevent downtime. - During growth spurts or higher CO2 demand, fine tune the bubble rate with the needle valve and rely on outlet pressure to maintain a steady flow into the aquarium.
