Description
Glass Drop Checkers for planted aquariums are small enough to appear unobtrusive, yet large enough to provide a clear and accurate CO2 reading.
CO2 Drop Checkers are used for long-term monitoring of the CO2 levels in the aquarium. A CO2 reagent is filled into those CO2Drop 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 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.
Fast response time.
Use to measure CO2 levels at-a-glance
PLEASE NOTE:
**Does not include 4 DKH solution**
CO2 Indicator Needs to Be Purchased Separately
