UP-AQUA CO2 Long Term Monitoring Reagent With Drop Checker

UP-AQUA CO2 Long Term Monitoring Reagent is for the monitoring of CO2 gas in the aquarium.
Can be used with glass or plastic drop checkers.
CO2 Drop Checkers are used for long-term monitoring of the CO2 levels in the aquarium. A CO2 reagent is filled into CO2 Drop Checkers and will change the colour according to the amount of dissolved CO2 in the aquarium water. Green will indicate a proper CO2 value, yellow will indicate too much CO2 and blue will show not enough CO2.
