Chihiros Drop Checker
Size: 42x46 mm
CO2 is one of the most important nutrients for aquarium plants. At the same time, too much CO2 can hurt other organisms of the aquarium. For this reason, long term monitoring of the CO2 levels in the aquarium is highly recommended. After inserting a CO2 reagent into the CO2 Drop Checkers and placing it in the aquarium, the color will change according to the concentration of dissolved CO2 in the aquarium water. Green will indicate a proper CO2 value, yellow will indicate to much CO2 and blue will show not enough CO2.
Please note that the required CO2 Drop Checker reagent is sold separately and does not come with this glass CO2 Drop Checker.
