In a planted freshwater aquarium the correct levels of CO2 are essential for healthy plant growth.
CO2 bottles include disposable cartridges and the larger, more sturdy steel CO2 bottles. Steel CO2 storage bottles have an external shut off valve and are supplied with a safety cage.
The Aqua Medic Station CO2 Storage Bottle is available in 500g, and also a large 2kg cannister. Please note that the 2kg is ordered directly from the manufacturers and takes up to 6 days for delivery, this unit also includes a stand.
If you are looking for a disposable option, the smaller Dennerle and JBL cannisters are an ideal option to use with the relevant CO2 sets.
