With the EHEIM CO2 sets, you increase your aquarium plants vitality and improve the water quality for your fish.

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.

With a choice of three complete sets, EHEIM offers the ideal CO2 system to suit your aquarium: a disposable system with a recyclable disposable bottle for aquariums up to 200 litres and two reusable systems with refillable bottles for aquariums up to 400 and 600 litres. ‘Complete set’ means all essential equipment and important accessories are included, ready for an immediate set up.
