CO2 & Plant Care

Aquarium water usually contains too little carbon dioxide (CO2) as it has already been extracted from the tap water at the waterworks.  In addition to light, nitrogen, phosphate and trace elements, etc., the most important nutrient for aquarium plants is CO2 and, the stronger and healthier the plants, the less chance algae has to grow. Plants also produce more of the oxygen that fish need to breathe and CO2 also regulates the pH values in the water, when dosed correctly. Complete with accessories, including: Precision pressure reducer with manometers and precise dosing valve for reusable systems 360° rotating hose connection CO² specific safety hose, pressure resistant, 3m, Ø 4/6 mm CO² safety diffuser including bubble counter and non-return valve for effective CO² dosing 5 x water test strips for analysis of the initial water values CO² long-term test and indicator reagent for permanently measuring of the CO² content in the aquarium Safe and toolfree installation Optional accessories (not included): CO² magnetic valve (night shut-off) Made in Germany 3 years guarantee

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. EHEIM CO2-diffuser 400for small and medium aquariums up to 400 l Small, effective device with an integrated bubble counter and non-return valve.  Easy to connect and attach to the aquarium pane with suction holder.  Advantages: Small, space-saving device Highly efficient diffuser Bubble counter for visual control of CO2 dosing Non-return valve prevents water returning to the CO2 system Hose protection Powerful suction holder

CO2- magnetic valves (night shut-off) (Solenoid valve) The magnetic valve enables you to switch off the CO2 supply in the aquarium if necessary – e.g. to regulate the pH or overnight.Up to 50% of CO2 can be saved by switching of the supply at night as photosynthesis only takes place in daylight where plants absorb carbon dioxide and release oxygen.  At night or without light, the plants consume oxygen, therefore CO2 fertilisation would not be beneficial. EHEIM CO2 – 24V magnetic valve for powerLED+ This magnetic valve has been specially developed for the EHEIM LEDcontrol+ lighting control system. It is connected to the EHEIM powerLED+ lighting and LEDcontrol+ and switches off the supply of CO2 during the sunset phase overnight. At dawn, the CO2 supply is reactivated. The magnetic valve can also be operated without LEDcontrol+ with a standard timer. Attention: The magnetic valve is not dimmable. Maintenance free Silent operation   Includes non-return valve Includes 1.5m cable  Made in Germany 3 year guarantee
