The UNS Drop Checker is a valuable tool designed to monitor and assist in maintaining optimal levels of CO2 in a planted aquarium. Drop checkers provide visual indication of CO2 concentration within the aquarium by changing color based on the pH level of the water. When CO2 concentration increases, pH drops and the drop checker's color indicator changes as a result. Aquarium drop checkers contribute to overall improved success of a planted aquarium through helping hobbyists maintain a balanced ecosystem.

What we like about the Ultum Nature Systems Drop Checker

Clean Design: UNS Drop Checkers come in two different styles to suit design and use preference. Each drop checker comes with a 15ml bottle of indicator solution for initial use. 30ml refill solution bottles are available when the solution retires and needs to be replaced.
