Eheim Single-use diving regulator CO2SET200

The CO2 fertilisation systems EHEIM reliably and accurately deliver the necessary amount of CO2 for healthy plant growth in your aquarium. Aquarium water almost always contains too little carbon dioxide (CO2). Plants in aquariums need light, nitrogen, phosphate, trace elements, and especially CO2 as the most important nutrient. The healthier the plants grow, the less likely algae are to develop. They also produce more oxygen, which fish need to breathe. Finally, CO2 also helps regulate the pH level of the water when dosed correctly. With three complete sets, EHEIM provides you with the ideal CO2 fertilisation system for your aquarium.
