This 3-in-1 Compact V-Shaped CO2 Diffuser performs as a CO2 bubble counter, check valve, and a diffuser - three functions in one! As a diffuser it enhances the contact time between carbon dioxide and your aquariums water, ensuring effective supplementation. As a bubbler, the transparent acrylic body allows you to easily monitor the dosing rate of CO2 into your aquarium. Plus, the stainless steel check valve effectively prevents back flow and siphoning!
