Tetra CO2 Optimat Refill

Tetra CO2 Optimat Refill provides optimum CO2 fertilisation for luscious, healthy aquatic plants. CO2  is an important plant nutrient, but the CO2 content in aquarium water is often insufficient. Tetra CO2 Optimat Refill offers you an easy way to add carbon dioxide directly at the touch of a button. Improved plant growth promotes the well-being of the fish and is the best way to prevent algae. A good level of oxygen in the water is also crucial for the well-being of all living creatures. In addition, healthy plant growth also provides the best way to prevent algae as aquarium plants absorb beneficial substances such as ammonia or ammonium during the photosynthesis process. This in turn improves the quality of the water. Finally, the deep green and red hues of aquatic plants form a key part of the harmonious underwater landscape, thus adding to an aquarium’s calming influence.
