Dupla CO2 Set Smart 250

The Dupla CO2 Set Smart is a complete set consisting of a CO2 fitting, atomiser, long-term test and silicone hose and is suitable for use with CO2 fertiliser systems in freshwater aquariums up to 250 litres.

The Dupla CO2 valve Smart is a CO2 pressure regulator with a preset, optimal working pressure and is, therefore, child's play to use. With the pressure-tight precision needle valve and the non-slip valve screw, the finest and most precise bubble number settings can be made. The reflux valve integrated into the fine needle valve protects the CO2 valve from water flowing back. The valve also has a pressure relief valve. The Smart CO2 fitting fits all common CO2 bottles (not included) with an external bottle valve. Thanks to the new knurled nut and the water jet cut flat gasket, it is easy to connect to the CO2 bottle without tools. The Dupla CO2 armature Smart is compatible with the CO2 solenoid valve Pro and can thus be used for semi-automatic control or via a fully automatic control with a pH controller. In addition, it is corrosion-resistant thanks to the material finishing. Thanks to the CO2 atomiser, which you attach far below on the inside of the pane, you enable very fine atomisation of the CO2 bubbles and thus optimal accumulation in the water. With the CO2 endurance test, you keep full control over your pH value and thus over the optimal CO2 supply. The gas-proof CO2 silicone hose enables you to connect securely.
