UNIFORM CO2 PRODUCTION

BIO-CO2 CONTROL GEL

The simple and safe method of CO₂ fertilization

CO₂ production and supply are carried out fully automatically and in the right quantities.
Nothing needs to be set or measured. The ultimate in simplicity and convenience.
This makes DENNERLE Bio-CO₂ ideal for all those who are as yet unaquainted with CO₂ fertilization and for those who may wish to try the method out. After only a few weeks of CO₂ fertilization, the results become evident: Plant growth improves substantially, the plants are greener, stronger and display greater vitality. The whole aquarium is brought to life.

Uniform CO₂ production with CO₂ control gel

DENNERLE Bio-CO₂ exploits the well-known fact that yeast cells are able to produce CO₂ from sugar in the absence of oxygen.
A problematic aspect is the fact that a fermentation process with pure sugar normally begins at a very fast pace, only to drop away substantially after just a few days. As a result, the aquarium receives too much CO₂ at the beginning, and too little shortly after.

In contrast, DENNERLE Bio CO₂ with CO₂ control gel produces a virtually constant level of CO₂ continuously for over 30 days, that is, for more than a month! Each CO₂ bottle produces well over 300,000 CO₂ bubbles. This assures your aquarium of an ideal supply of CO₂ every day.
