The Spiral Bubble Counting Diffuser is a pollen style CO2Â diffuser that connects to CO2Â injection systems to easily disperse CO2Â gas into the planted aquarium. The built-in spiral bubble counter allows for easy monitoring of the rate of CO2Â injection. The inclusion of a bubble counter in the diffuser makes the use of a bubble counter on the CO2Â tank or in-line unnecessary. The Spiral Bubble Counting Diffuser has a 30 mm disc.
Compatible with 6 mm (1/4") - Standard Airline Tubing. Suction cup included.
