Seachem Beetle Diffuser - Pollen Style CO2 Diffuser

  • For Aquariums 20-50 Gallons
  • Pollen-Style Diffuser for Large or High-Growth Aquaria
  • Large Surface Area is Ideal for High Volumes of CO2
  • Available in Two Sizes


The glass Beetle 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 disc allows for the diffusion of large volumes of CO2 gas, making it an excellent choice for larger or high-growth aquaria.



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 repositioning the diffuser, pull by the suction cup(s) rather than the glass to avoid breakage.

Install check valve (not included) in line with tubing outside of the aquarium.

Once securely mounted, turn on CO2. Observe bubble count and adjust CO2 to desired flow rate.
