This glass CO2 Drop Checker set can be used on both rimless aquarium tanks AND rimmed aquarium tanks!

This high-quality glass CO2 Drop Checker allows for visual monitoring of CO2 injection levels. The pH reagent solution that is also included in this set will change colors to indicate whether there is an excessive, optimal, or insufficient amount of CO2 being injected into a planted aquarium. The result is an extremely simple guide to judge the amount of CO2 that is administered, ensuring the health of aquatic plants and the livelihood of fish and shrimp.

SMALL [2 x 1"]
LARGE [2.5 x 1.2"]

There is no functional difference between the small or large size. A larger glass CO2 drop checker provides increased visibility compared to the small one in larger planted aquarium tanks.

The picture below is the Glass CO2 Drop Checker Set that works for rimless aquariums only. Both products work the same!
