Azaqua CO2 Checker Edge
How much CO2 should you add to the aquarium?
At a glance, this handy CO2 checker gives the simple answer to the apparently difficult question: If the liquid in the CO2 checker turns green, the CO2 content in the aquarium is optimal for plant growth. If the color is blue, there is too little CO2 and if the liquid turns yellow, there is too much CO2.
The CO2 checker Edge can be hung over the edge of the aquarium. This is an exceptionally stylish solution for aquariums without a frame with a glass thickness of up to 10mm! An air bubble is created in the CO2 checker, allowing gas exchange between the liquid and the aquarium water to take place.
A suction cup is not necessary and there is only a glass tube in the aquarium. Virtually nothing is disturbing in the view and the color of the CO2 indicator fluid is quick and easy to read!
For glass thickness 8mm or smaller
PLEASE NOTE: excluding CO2 check / indicator fluid
Our tip: Choose the Azaqua CO2 indicator fluid when purchasing.
