The Carbo Bio Start bio CO2 fertiliser systems supply freshwater aquariums with a volume of up to 60 litres, or in the case of the Biostart 80, aquariums up to 80 litres, with vital CO2. The fertiliser system is ready for operation in just a few steps. CO2 production starts after only 24 to 48 hours. A pressure-resistant CO2 hose and a CO2 diffuser specially designed for low operating pressure - or optionally, a CO2 injector for connection to a Dennerle Corner Filter 40 or 60 - ensure fast, effective dissolution of the CO2 in the aquarium water.

Plants consist of almost half carbon. CO2 is therefore their most important nutrient. It serves as the basic building block of photosynthesis. Because from CO2, water and light, plants produce their most important building material and energy source: sugar. The "waste product" is oxygen.
Without the addition of CO2, the level in aquariums is always too low. The plants therefore grow only slowly or not at all. This in turn means danger of algae problems. Well-growing aquatic plants are the best prevention against algae! Only a regular addition of CO2 creates the natural basis for healthy, strong plant growth, lush green leaves and bright colours.

The carbon is produced by a 100 % natural bio-reaction. Selected microorganisms, in combination with the CO2 Constant gel developed by Dennerle, supply an almost constant amount of CO2 (per filling) for at least 40 days. In conventional DIY Bio CO2 systems that work with white household sugar, CO2 production is usually very irregular. It usually starts very quickly, but drops again sharply after just a few days, i.e. too much CO2 is produced at first, and too little later. These systems are therefore less suitable for aquaristic practice.
