CO2 Drop Checkers are used for long-term monitoring of the CO2 levels in the aquarium. For optimal plant growth, it is important to know If you're getting the desired saturation of Co2. Over dosing of CO2 can lead to the death of fish; under dosing can stunt the growth of plants. A CO2 reagent is used to fill the CO2 Drop Checker & attached on the inside of the aquarium away from the outflow. The solution will change color according to the amount of dissolved CO2 in the water column.
