The 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 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 bubble counter on the CO₂ tank or in-line unnecessary. The Bubble Counting Diffuser has a 17 mm disc.

Compatible with 6 mm (1/4") - Standard Airline Tubing. Suction cup included.
