The Tetra CO2 Optimat Refill provides the replacement CO2 bottle for the Tetra CO2 Optimat Set.
Carbon is an important nutrient for all aquatic plants and is absorbed by them as Carbon Dioxide. While the amount of Carbon Dioxide in the atmosphere is almost inexhaustible, aquarium water usually always contains too little carbonic acid. Using the Tetra CO2 set you can easily enrich your aquarium water with CO2 to improve plant growth and health.
