Dennerle Nano CO2 Starter Kit Basic

The Dennerle Nano CO2 Starter Kit Basic harnesses bio-CO2 technology, relying on a simple sugar-and-yeast fermentation reaction to produce a steady, gentle stream of carbon dioxide for tanks up to approximately 60 litres. No pressurized cylinder, regulator, or solenoid is required, making setup beginner-friendly and cost-effective. The kit includes a reaction vessel, Dennerle BIO-CO2 activator, a mini bubble counter, CO2 diffuser, and tubing — everything needed for plug-and-play operation. CO2 output is sustained for several weeks per charge before the activator needs replacing, keeping ongoing costs low. This kit is an excellent first step for hobbyists wanting to experience the benefits of CO2 fertilisation in small planted or shrimp tanks without committing to a full pressurized system.
