Seachem Glass Beetle Diffuser

Enhance COx distribution in your planted aquarium with the Seachem Glass Beetle Diffuser. Designed for both performance and aesthetics, this elegant glass diffuser produces a fine mist of micro-bubbles, ensuring efficient COx absorption by aquatic plants while blending seamlessly into your aquascape.

Its compact “beetle-style” design makes it ideal for small to medium aquariums, providing excellent diffusion without distracting from the layout. Built from high-quality glass and featuring a precision ceramic disc, this diffuser delivers consistent, reliable COx performance.

Care & Use Instructions

• Attach to your CO₂ tubing and place inside the aquarium using suction cups

• Position low in the tank for best CO₂ circulation

• If performance drops, clean the ceramic disc by soaking in a mild bleach solution, then dechlorinate thoroughly before reuse
