Tetra CO2 Test

The Tetra Test CO2 is used to precisely determine the carbon content in a freshwater aquarium.

Healthy and splendid plant growth depends on three essential factors: in addition to a nutrient-rich substrate and optimal lighting, plants need a carbon source for their photosynthesis. With this, they produce vital oxygen in the aquarium and thus contribute significantly to the well-being of your fish! With the Tetra CO2 Optimat, you can offer your aquatic plants the perfect basis, which they thank not only with dense and lush growth but also with vital fish. Healthy plants reduce algae nutrients and pathogens and absorb pollutants. In addition, the water is slightly acidified, which brings about a pH stabilisation - advantageous, since most of the well-kept fish come from rather acidic waters anyway!

With the Tetra CO2 test you can quickly and precisely determine the CO2 value of your aquarium water.

The contents of delivery include 2 x 10 ml test reagents, 2 measuring tubes, colour scale, instructions for use and recommendations.
