An essential tool for the aquarium hobbyist. The UNS Drop Checker makes CO2 monitoring quick and simple. Available in two styles, the drop checker is filled with indicator solution and placed into the desired aquarium. The device works by providing a visual reading of the aquarium’s pH level. When CO2 levels are elevated, pH drops respectively, resulting in a yellow to green solution color. When the presence of CO2 is null, the drop checker will show a blue tone. Safe and simple to use, hobbyists can make necessary adjustments to CO2 systems to properly support the specific aquarium’s needs.
