Carbo Bio Style 120 by Dennerle is a CO2 fertilisation system for freshwater aquariums up to 120 litres. It is easy to set up, starts CO2 production within 24-48 hours and has an organic CO2 diffuser specially developed for low operating pressure. Its modern and timeless design blends in easily next to your aquarium. Additional safety features such as a pressure relief valve and pressure-resistant CO2 hose and hose fittings ensure safe operation. Plus it is sustainable thanks to the refillable stainless steel reaction tank and the CO2 Constant gel which is made from 100% renewable raw materials.

Carbon: the basis of plant life
Plants are made up mostly of carbon. CO2 is an essential nutrient and the building block for photosynthesis by which they produce sugar from CO2, water and light and release oxygen.

The natural CO2 content in aquariums is often too low, thus causing slow plant growth and algae problems. Regular addition of CO2 creates the right conditions for healthy plant growth, more oxygen and better water quality.

CO2 production
Carbon is produced in a natural biochemical reaction. Specially selected microorganisms in combination with Dennerle's CO2 Constant Gel ensure a constant amount of CO2 per filling for at least 40 days. Conventional organic CO2 systems which use household sugar produce CO2 irregularly and are less suitable for aquariums.
