CO2 Drop Checker with Solution

CO2 Drop Checker with Solution

CO2 Drop Checker with Solution help to easily monitor the CO₂ levels in your aquarium. Designed for accuracy and simplicity, this kit ensures your aquatic plants get the optimal amount of CO₂ for healthy growth while preventing unsafe levels for your fish.

Included in the Kit:

• CO₂ Drop Checker – Made from high-quality, transparent glass for clear visibility.

• Suction Cup – Securely attaches the drop checker to the inside of your aquarium for easy placement and viewing.

• CO₂ Indicator Solution – Pre-mixed and ready to use, giving quick and accurate readings.

How it Works:
When placed in your aquarium, the drop checker changes colour according to the CO₂ concentration in the water — blue for low, green for optimal, and yellow for high levels — making it easy to keep your tank balanced.
