It is easy to connect and can be securely attached to the aquarium glass using a suction holder. Advantages: Compact, space-efficient design Highly effective diffusion of CO2 Bubble counter for easy visual monitoring of CO2 levels Non-return valve to prevent water from flowing back into the CO2 system Protective hose feature Strong suction holder for secure attachment

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

Water Testing (Long-Term Evaluation) It is essential to consistently monitor the CO2 levels in your aquarium, as the pH of the water is greatly affected by CO2 addition. Ongoing monitoring should always incorporate a long-term CO2 test along with indicator liquid and water test strips designed for a CO2 fertilization system. EHEIM CO2 Long-Term Test Set A comprehensive kit for the continuous assessment of CO2 levels in your aquarium, featuring a long-term test, indicator liquid, and three test strips for evaluating your initial water parameters. The CO2 long-term test conveniently attaches to the aquarium glass using a suction cup and is filled to the marked line with aquarium water (approximately 1 ml). Add four drops of the indicator liquid, and after a brief wait for the color to change, compare the resulting color to the provided scale. The scale indicates the corresponding pH values based on the water's carbonate hardness (dKH). EHEIM Long-Term Test with Suction Cup Indicator liquid - 10 ml for about 90 applications 3 x 5 multi water test strips for evaluating initial water parameters and determining carbonate hardness (dKH), which is crucial for CO2 fertilization. High Quality Made in Germany EHEIM CO2 Indicator Fluid - Long-Term Test Indicator fluid - 10 ml for approximately 90 applications (4 drops each) EHEIM TEST – 5 in 1 15 x multi water test strips for quick and easy assessment of the five most critical water parameters in your aquarium and pond: NO2, NO3, GH, KH, and pH.

The EHEIM CO²Set600 without bottle is designed to address the common issue of low carbon dioxide (CO2) levels in aquarium water, which often occurs after the tap water has been treated at the waterworks. CO2, alongside light, nitrogen, phosphate, and trace elements, is a vital nutrient for aquarium plants. Strong and healthy plants reduce the likelihood of algae growth. Additionally, plants contribute to oxygen production, which is essential for fish respiration, while CO2 helps to balance the pH levels in the water when applied correctly. This complete set comes with all necessary accessories, including: Precision pressure reducer equipped with manometers and an accurate dosing valve for reusable systems 360° rotating hose connection CO²-specific safety hose, pressure resistant, measuring 3m, Ø 4/6 mm CO² safety diffuser that includes a bubble counter and non-return valve for effective CO² dosing 5 water test strips for evaluating initial water parameters CO² long-term test and indicator reagent for continuous measurement of the CO² levels in your aquarium Simple and tool-free installation Optional accessories (not included): CO² magnetic valve for nighttime shut-off. Manufactured in Germany and backed by a 3-year guarantee.

EHEIM CO2 - 230V Magnetic Valve CO2 Magnetic Valves (Night Shut-Off) (Solenoid Valve) The magnetic valve allows you to turn off the CO2 supply in your aquarium when needed, such as for pH regulation or during the night. By shutting off the CO2 supply overnight, you can save up to 50% of CO2 since photosynthesis occurs only during daylight when plants absorb carbon dioxide and release oxygen. At night or in the absence of light, plants utilize oxygen, making CO2 fertilization unnecessary. This magnetic valve operates on a 230V alternating current and is most effective when connected to an aquarium light timer. This setup enables the valve to turn off simultaneously with the aquarium lights. Benefits: Maintenance-free Quiet operation Includes non-return valve Comes with a 1.5m cable Manufactured in Germany 3-year guarantee Technical Specifications: 230 V/50 Hz 1.6 WP Max 6 bar ø 4/6 mm Waterproof (IP65)
