Pro-Elite Series Complete Kit is the highest quality CO2 System available in the aquarium market. This CO2 System is a combination of our best rated dual stage regulator Pro-Elite Series and latest inline CO2 diffuser.

If you are looking a piece of mind, this regulator will give you the best pressure stability with unbeatable 10 years warranty!

Additionally, with expandable manifold blocks, you will be able to add additional outlets and use this regulator with multiple diffusers.
