Tetra CO2 Plus is a liquid carbon fertiliser for healthy plant growth in freshwater aquariums.

Only with healthy, magnificent aquatic plants does an aquarium become an optical eye-catcher. Their green often really brings out the colours of the fish. Without the variety of plants, many aquariums would appear bare, the fish would lack hiding places and possibly spawning grounds. Plants not only serve as a decorative element but also perform important biological functions in the aquarium. They enrich the water with oxygen and reduce nitrogen compounds. There are also fish and invertebrates that tirelessly scrape unicellular organisms and algae from the leaves all day long. So they are also a settlement area for feed. Three factors are necessary for healthy plant growth: the nourished substrate, sufficient light and a carbon source with which plants carry out photosynthesis and thus ensure the oxygen content in the aquarium. Vigorous plant growth is the best way to prevent algae growth.

Tetra CO2 Plus is an essential nutrient for healthy and abundant plant growth. Tetra CO2 Plus adds carbon to the water in a form that is available to plants. The biological release of CO2 works for up to a week. The aquarium plants develop stronger and healthier. The application is simple and requires no additional tools. Vigorous plant growth is the best way to prevent algae.

Application
Add 2.5 ml weekly to 20 litres of aquarium water. Use twice a week for heavy planting.
