EHEIM CO²Set600 without bottleAquarium 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 systems360° rotating hose connectionCO² specific safety hose, pressure resistant, 3m, Ø 4/6 mmCO² safety diffuser including bubble counter and non-return valve for effective CO² dosing5 x water test strips for analysis of the initial water valuesCO² long-term test and indicator reagent for permanently measuring of the CO² content in the aquariumSafe and toolfree installationOptional accessories (not included): CO² magnetic valve (night shut-off)Made in Germany3 years guarantee

Water test (long term test)In principle, you should always monitor the CO2 content in your aquarium because the pH value of the water is significantly influenced by the addition of CO2. Permanent monitoring should always includes a long-term CO2 test and indicator liquid as well as water test strips for a CO2 fertilizer system.EHEIM CO2-long term test setA complete set for constant monitoring of the CO2 content in the aquarium, including a long term test, indicator liquid and 3 test strips for analysis of the initial water values.The CO2 long-term test is attached to the glass in the aquarium with a suction cup and filled, to the indicated mark, with aquarium water (approx. 1 ml). Add 4 drops of indicator liquid and wait for the colour to change and then compare the indicator colour to the colour scale.Depending on the carbonate hardness (dKH) of the water, the scale will show the corresponding pH values.EHEIM long term test with suction cupIndicator liquid - 10 ml for approx. 90 applications3 x 5 multi water test strips for analysis of the initial water values and determination of the carbonate hardness (dKH) important for CO2 fertilisation.High qualityMade in GermanyEHEIM CO2-indicator fluid - long term testIndicator fluid - 10 ml for approx. 90 applications (4 drops each)EHEIM TEST – 5 in15 x multi water test strips for easy and fast determination of the 5 most important water values in aquarium and pond: NO2, NO3, GH, KH and pH.Packing: 50 pcs. of 5 multi test strips

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.Advantages:Maintenance freeSilent operation Includes non-return valveIncludes 1.5m cableMade in Germany3 year guaranteeTechnical data: 24 V DC, 1,5 WP max 6 barø 4/6 mmwaterproof (IP65)

EHEIM CO2 - 230V magnetic valveCO2- 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.The magnetic valve operates with a 230V alternating current and works best when connected to the aquarium light timer. This allows the magnetic valve to be switched off at the same time as the lights.

CO2-DiffuserThe 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 600for larger aquariums up to 600 lQuality 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.Advantages: User-friendly device with large diffuser areaOptimum distribution of CO2 bubbles in large aquariumsSeparate bubble counter for visual control of CO2 dosingIntegrated non-return valve prevents water returning to the CO2 systemSafe hose connectionSpace-saving corner mounting with two powerful suction holders
