The Colombo CO2 Indicator is a drop test that allows you to quickly and visually know the CO2 level in the aquarium. Thanks to a colored reagent, it indicates at a glance whether the CO2 supply is insufficient, optimal, or excessive.
Small in size and equipped with a suction cup, the drop checker can be easily and discreetly placed in the tank, without affecting the aquarium's aesthetics.
The CO2 level and the pH of the water are essential parameters that have a direct impact on the health of the fish and the growth of aquatic plants. The Colombo CO2 Indicator is one of the most reliable tools for monitoring these parameters, especially when starting a new aquarium.
A well-controlled CO2 supply promotes plant growth. On the other hand, an excess can lead to acidosis, which is potentially dangerous for the fish, hence the importance of regular monitoring.
Blue color: CO2 level too low.
Green color: Optimal CO2 level.
