SEACHEM GLASS BUBBLE COUNTING SPIRAL DIFFUSER - POLLEN 23MM DISC (SC-3157)

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 bubble counter on the CO2 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.
