Azaqua CO2 Checker M
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 dimensions of the CO2 checker have been conveniently chosen for every type of aquarium from small to large. With the supplied suction cup it can be attached to the glass in any desired location. The CO2 content can be measured at various places in the aquarium. This allows you to check whether the flow is good and the CO2 is distributed throughout the entire aquarium.
Includes: suction cup
