Aquarium CO2 Kits, Diffusers, Cartridge Refills & Parts

We stock a range of C02 systems, diffusers, refills and other accessories to help make your aquatic plants more vigorous and robust.
The Aquarium gardener who chooses not to dose CO2 or any kind of macro or micro nutrients will be 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.

Using Carbon Dioxide makes plants more beautiful and much more colorful than those plants which are left to scavenge for the limited nutrients naturally available in the aquarium.
