Fluval’s innovative solutions enable you to integrate precise and controlled CO2 supplementation into your aquarium, fostering lush plant growth and enhanced water quality.

The Fluval Bio-CO2 Low-Pressure System is a groundbreaking innovation that marries the safety of biological CO2 production with the convenience of a pressurized gas system.

An adjustable bubble counter with a precision valve and a nano-bubble diffuser ensure even and efficient CO2 distribution throughout the aquarium. Additionally, the system is equipped with an overpressure/pressure relief valve for added safety.
