The Bubble Counter is a simple and safe unit for monitoring the dosage of CO2 gas into aquaria and filter components. Designed to be installed in the low pressure section of your gas delivery system, the Bubble Counter visually displays the flow rate of CO2 gas as it is being delivered. This allows fine adjustments to be made and easily verified. An integrated non-return valve prevents water back flow and the holding plate lets you install the Bubble Counter in an easily viewable area. The Bubble Counter is an invaluable tool whether you are feeding a CO2 Reactor for live plants or regulating the pH inside a Calciumreactor, the visual display of flow rate helps ensure you are getting the most from your CO2 gear.
