Fluval Bio Co2 125L

The Bio-CO2 Pro Low-Pressure System combines the safety of biological CO2 production with the convenience of pressurized delivery, offering both simplicity and exceptional performance. This easy-to-use system delivers reliable and controllable CO2 through a natural fermentation process, making it ideal for growing and maintaining vibrant live aquatic plants.

Designed for both new and experienced hobbyists, the Bio-CO2 Pro operates at a safe low pressure of 1.3 bar (19 psi), compared to traditional high-pressure systems. It provides up to 30 days of consistent CO2 production using sustainable raw materials like sugar and yeast, and eliminates the need for refilling high-pressure cylinders.

Maintenance is straightforward with a quick 4-step process taking less than 10 minutes per month. The high-quality stainless steel reaction chamber, equipped with a 100% silicone gasket, prevents CO2 leakage. It features an adjustable bubble counter, precision regulator, and nano bubble diffuser for accurate CO2 delivery, along with a pressure release valve for added security.

The system includes Bio-CO2 Activator yeast and Booster tablets, with refill packs available separately. For best results, add tap water at 80–85 °F (27–30 °C) and maintain a room temperature of 68–72 °F (20–22 °C). Developed in Germany, the Bio-CO2 Pro system is also compatible with CO2 level tests (sold separately).
