The Dennerle Bio-CO2 Supply Bottle is used for biological CO2 production in freshwater aquariums and as replacement part for Bio-CO2-Complete-Set. It provides uniform CO2 production through CO2 control gel. Each CO2 Supply Bottle produces well over 300.000 CO2 bubbles. The Supply Bottle is available individually or in a value pack with two bottles.
Dennerle has been operating in Vinnigen since its foundation in 1966 and, after more than 50 years of company history, the building blocks Dennerle relies on is experience. The philosophy behind Dennerle is to create a small and tangible, intact piece of nature, in harmony with the natural environment. That is why sustainability is a company-wide concept and is implemented at every possible point. In order to achieve an ecologically balanced aquarium, Dennerle relies on a system that is based on 5 pillars. Animals, plants, water, substrate and lighting. Dennerle offers the optimum equipment to bring this complex, but not complicated system into harmony.
