During photosynthesis plants combine carbon dioxide with water to produce sugar and oxygen. Land plants absorb the carbon dioxide they need from the air, while aquatic plants use carbon dioxide that is dissolved in the water. The amount of carbon dioxide in aquarium water tends to be quite low, and this places a restraint on the rate at which plants can photosynthesis. By adding extra carbon dioxide aquarists can reduce this restriction and thereby allow plants to photosynthesise more quickly. The quicker plants photosynthesise, the more sugar and oxygen they produce, and the faster they will grow.
Although carbon dioxide fertilisation will benefit all planted aquaria to some degree, the value of carbon dioxide fertilisation is often misunderstood. Furthermore, the methods used to provide carbon dioxide fertilisation are varied, expensive, and in some cases potentially dangerous if not used properly. Finally, carbon dioxide fertilisation isn't a magic bullet that cures all ills; there are many situations where other problems, such as poor lighting, are restricting plant growth
