Seachem Spiral Bubble Counting Diffuser - Pollen Style CO2 Diffuser

  • For Aquariums from 20-50 Gallons
  • Large Surface Area of Diffuser Disc for High Volumes of CO2
  • Built-In Bubble Counter


The Spiral Bubble Counting Diffuser is a pollen style CO2 diffuser that connects to CO2 injection systems to easily disperse CO2 gas into the planted aquarium. The built-in spiral bubble counter allows for easy monitoring of the rate of CO2 injection. The inclusion of a bubble counter in the diffuser makes the use of a separate bubble counter on the CO2 tank or in-line unnecessary. The Spiral Bubble Counting Diffuser has a 30 mm disc.



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. It should be positioned low in the aquarium. When removing or repositioning the diffuser, pull by the suction cup 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.
