CO2 glass diffusers efficiently distribute CO2 in a planted aquarium. The micro bubbles produced are able to pollinate an entire aquarium, effectively allowing aquatic plants to absorb CO2 properly. Its design allows the user to place it in the corner of a planted aquarium securely with 2 suction cups. Alternatively, it can also be placed on the side of an aquarium using a single suction cup. Its glass design allows for better aquarium viewing without distraction.

For tanks 30 gallons and larger.
