CO₂ Drop Checker

Aquasabi - CO2 Drop Checkers

In aquascaping, glass CO₂ long-term test containers are also commonly referred to as drop checkers. The drop checker is filled with an indicator liquid whose color change shows you the current CO₂ level in the aquarium water. Green stands for sufficient, yellow for too much and blue for too little dissolved carbon dioxide in the water. As the manufacturer of this beautiful glassware, we at Aquasabi offer several variants of these stylish CO₂ drop checkers. In addition to the classic drop checker in two sizes, the Hang-On Checker is ideal for rimless aquariums without a cover. Particularly stylish, and also available in different diameters, are the round Orb Checkers from Aquasabi.
