The kit comes with the glass bulb equipped with a suction cup for adhering to the inside of the aquarium, and a 15ml bottle of drop checker solution.Fill the glass bulb with the solution (no dilution necessary) and install it in your aquarium to monitor CO2 levels.Blue = not enough CO2, Yellow = too much CO2, Green = appropriate amount of CO2.Give the solution at least an hour or two to develop before determining whether or not to adjust your CO2 levels, as it takes some time for the color to stabilize.
