TNA Glass CO2 Indicator

TNA Drop Checker planted for 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 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.

    Fast response time
    Use to measure CO2 levels at-a-glance
    CO2 regent included

The glass design looks nice, doesn't look cheap like other plastic-made drop checkers. Easy to set up and read. I don't have any way to verify the accuracy, but I can say that my CO2 injected tank reads yellow, and my non CO2 injected tank reads green, so there is certainly a correlation between color reading and CO2 level.
