TOP AQUA Long Term CO2 Glass Monitor
CO2 Glass Indicator for planted aquariums are small enough to appear unobtrusive, yet large enough to provide a clear and accurate CO2 reading.
CO2 Checkers are used for long-term monitoring of the CO2 levels in the aquarium. A CO2 reagent is filled into those CO2 Drop Checkers and will change the color according to the amount 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.
It is hand-crafted using only the highest quality, laboratory-grade, borosilicate glass for maximum strength, durability, and visual clarity.
