CO2 Diffuser The CO2 gas is transformed into numerous tiny bubbles by the diffuser. These bubbles increase the contact area, allowing the CO2 to dissolve swiftly in the aquarium water. The bubble counter provides a visual reference for monitoring CO2 dosage. A general guideline is to aim for approximately 20 mg of CO2 per litre, which equates to around 10 bubbles per minute for every 100 litres of water. EHEIM CO2 Diffuser 600 Designed for larger aquariums up to 600 litres, this high-quality glass CO2 diffuser features a separate bubble counter and a reliable non-return valve, ensuring efficient and lossless CO2 dosing. The expansive diffuser surface guarantees optimal and effective distribution of CO2 bubbles throughout larger tanks. It also offers a space-saving corner installation, secured with two robust suction holders. Benefits: User-friendly device with a generous diffuser area Optimal distribution of CO2 bubbles in expansive aquariums Separate bubble counter for easy monitoring of CO2 dosage Built-in non-return valve to prevent water from flowing back into the CO2 system Secure hose connection Compact corner installation with two strong suction holders
