CO2 bubble counter

Specifications

Description

A bubble counter makes the gas moving through a CO2 line visible as bubbles passing through water. It helps you observe the supply while adjusting the regulator's fine-control valve. The counter is an indicator of that supply, not the valve that changes it. The amount to supply depends on the planted aquarium; a bubble count is not a universal setting for every tank. Common arrangements include an external glass counter connected with flexible tubing, an inline counter with hose connections, and a screw-mounted counter for a compatible needle valve. Some have a built-in check valve; others require a separate one. ADA's glass counter is installed upright outside the aquarium with soft tubing and a separate check valve. JBL's COUNT SAFE has backflow protection built in and can mount with suction cups or screws. Choose the mounting arrangement first, then check the precise hose or threaded connection for the selected variant. The clear chamber is not necessarily glass: the Clscea single-head model uses a polycarbonate chamber with aluminum-alloy ends. Fill and service the counter according to its own instructions. ADA's installation procedure fills the counter before connection and adjustment; a refill feature on another product is not a general instruction to open or refill any counter while CO2 is flowing.
