EHEIM 600L CO2 Set 600 difusser and bubble counter

The CO2 gas is atomized into many bubbles by the diffuser. The bubbles create a larger contact surface enabling the CO2 to dissolve quickly in the aquarium water. The bubble counter visually controls the dosing of the CO2. As a rough rule of thumb: approx. 20 mg CO2 per litre. This corresponds to about 10 bubbles per minute per 100 litres of water. Features: - Quality glass CO2 diffuser with separate bubble counter and safe non-return valve for effective and loss-free CO2 dosing. - The large diffuser area ensures optimum and effective distribution of CO2 bubbles in large aquariums. Space-saving corner mounting with two powerful suction holders. Specifications: - Freshwater: Yes
