The 30mm glass Beetle Diffuser is a pollen style CO₂ diffuser that connects to CO₂ injection systems to easily disperse CO₂ gas to the planted aquarium. The large surface area of the 30mm disc allows for the diffusion of large volumes of CO₂ gas, making the 27 mm Beetle Diffuser an excellent choice for mid-sized aquaria or higher-growth aquaria.
