Glass Beetle CO2 Diffuser 27mm

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

Compatible with standard 4mm airline tubing. Suction cups included.

Directions
Rinse glassware with warm water. Attach suction cup and desired tubing to the diffuser.

To attach tubing to glassware, wet the inside of the tubing with water at the attachment point and carefully slide tubing over glass. The use of other lubricants is not advisable as these usually make the tubing slide off of the glassware too easily. To avoid breakage when removing tubing, do not pull tubing off of glassware. Instead, cut tubing carefully along the attachment length to release the glassware.

Mount your diffuser using the suction cup(s). It should be positioned low in the aquarium. When removing or re-positioning the diffuser, pull by the suction cup(s) rather than the glass to avoid breakage.

Install check valve (not included) inline with tubing outside of the aquarium

Once securely mounted, turn on CO2. Observe bubble count and adjust CO2 to desired flow rate. Some of Seachem’s diffusers have a bubble counting feature. Otherwise a separate Seachem Glass CO2 Bubble Counter is available.
