Regular price $341.96

Pro-Elite Series Complete Kit is the most advanced CO2 System available in the aquarium hobby. This system is being used by both professionals and amateurs all over the world being a part of the best aquascapes ever. 

This reliable CO2 System comes with our best-rated Pro-Elite CO2 Regulator allowing the user to run multiple diffusers due to the extendable manifold block system. Its dual-stage construction minimizes the increase in output pressure as pressure drops in the gas cylinder and will prevent end-tank-dump keeping your livestock safe and the CO2.

The system is equipped with our New CO2 In-line diffuser, allowing the user to install it outside the aquarium, leaving more space for plants or fish. The diffuser contains a replaceable ceramic membrane made with Fine Mist Technology providing the best dissolution rates. Depending on your filter output, it comes in two sizes: 12/16mm and 16/22mm.

For safe and reliable CO2 injection, the CO2 System contains high-quality CO2 resistant CO2 tubing available in 5 colors and 3 lengths. All our CO2 tubes are compatible with all CO2Art products. 

To measure the amount of CO2 present in the water constantly, the Drop Checker Kit is included into the Pro-Elite Series Complete Kit. If the liquid in the glass chamber is green lime, the CO2 level is safe for your livestock. This visual indicator is more than helpful in daily tank maintenance.
