CO2



CO2 in the Aquarium



The Aquarium gardener who chooses not to dose CO2 or any kind of macro or micro nutrients will be unfortunately missing out on a big part of the freshwater plant hobby. Without dosing it is much more difficult to grow some of the more exotic water plants. With its use the plants are more vigorous and robust,appear more beautiful and much more colorful than those plants which are left to scavenge for the limited nutrients naturally available in the aquarium.
