FLUVAL BIO CO₂ 125L – Natural Fermentation-Based CO₂ System for Planted Aquariums up to 125 Liters
Fluval BIO CO₂ 125L is a complete and eco-friendly carbon dioxide (CO₂) system that provides consistent, biologically generated CO₂ to freshwater aquariums up to 125 liters. Through a natural fermentation process, the system produces CO₂ for 30 days, enhancing photosynthesis and promoting vibrant plant growth without the use of pressurized gas cylinders.
BIO-CO₂ Pro features high-grade stainless steel components, including a precision-adjustable bubble counter, nano bubble diffuser with ceramic disc, check valve, CO₂-resistant tubing, safety overpressure release valve, and a secure reaction chamber with silicone seal. The system uses yeast, warm water, and sugar (not included) to create CO₂ safely and efficiently.
