Cal Aqua Glass CO2 Diffuser

The Cal Aqua Glass CO2 Diffuser is individually hand-blown from high-grade borosilicate glass, resulting in a beautiful, transparent piece of functional aquarium art that enhances the visual appeal of any planted display tank. The finely sintered ceramic disc embedded in the glass body produces an exceptionally fine mist of micro-bubbles that dissolve rapidly into the water column, delivering outstanding CO2 efficiency comparable to premium inline diffusers. Unlike plastic diffusers, the glass construction is completely inert and resistant to discolouration, algae staining, and chemical degradation over years of use. The elegant form factor mounts to the aquarium glass via a suction cup bracket and complements the natural aesthetics of Amano-style aquascapes. Suitable for aquariums of all sizes; choose bubble count based on CO2 flow rate and tank volume.
