Aquatic plants have two basic requirements- CO2 and light. A proper CO2 system is beneficial for healthy planted aquariums.

Three main things are crucial for aquatic plant growth. CO2 is one of them! If any of the factors are unbalanced, unsightly algae have the chance to grow and overtake a planted aquarium. Using CO2 in a planted tank gives aquarium plants the boost they need to thrive and grow efficiently. With added strength, they are also able to out-compete algae for sources of nutrients in the aquarium. The use of CO2 in a planted tank leads to full and bushy growth that all aquarium hobbyists are striving for.
