CO2 Drop Checker Kit for Injected Aquariums with Low-Iron Glass and Ready-to-Use Indicator Solution

Keep track of carbon dioxide in an injected aquarium through a simple colour check. This complete drop checker kit gives pet parents and aquarists a convenient way to monitor the CO2 dissolved in the water column as part of their regular tank-care routine.

The low-iron glass checker mounts directly to the aquarium glass, keeping the visual indicator easy to see without taking attention away from the tank.

Key Features

• The pH reagent changes colour according to the amount of CO2 diluted in the aquarium water, turning an invisible parameter into an easy visual check.
• A deep-green reading indicates that a safe amount of carbon dioxide has been diluted in the water column, providing a clear reference for routine monitoring.
• The included 15 ml solution requires no mixing or preparation, so the checker can be set up without measuring or blending reagent.
• A high-quality suction cup provides solid positioning on the aquarium glass, keeping the indicator in a consistent, visible location.
• Low-iron glass gives the checker a clean, unobtrusive appearance that fits neatly into the aquarium display.
• The kit contains the components needed to begin monitoring CO2 levels in an aquarium that uses carbon dioxide injection.
