Fluval Replacement Diffuser Part for BIO-CO2 Pro 250L Aquarium Diffuser

Routine disc replacement is common in a CO2 system and should be done every few months to maintain optimal carbon dioxide delivery. The Fluval CO2 Diffuser (250 L size) features a high-quality ceramic disc that produces a fine mist of CO2 bubbles, ensuring efficient dissolution of CO2 into the aquarium for healthy plant growth.
