## Description

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 the CO2 level in the water column for the health of your fish and the plants. Over dozing of CO2 will lead to the death of fish; under dozing will stun the growth of your plants. A CO2 reagent is filled into the CO2 Drop Checker, then affixed the checker to the glass under water. The solution will change the color according to the amount of dissolved CO2 in the water column.
