Supply of CO2 without diffuser
Sometimes technical devices, such as a CO2 diffuser inside the tank, can spoil the look of an aquarium. JBL has developed a direct diffuser which is simply integrated into the water hose coming from the external filter, and the diffuser stays outside the tank.
Thanks to a macromolecular PE diaphragm, the new JBL ProFlora Direct saves 20 % CO2 consumption. It contains an integrated check valve, which prevents water backflow into the CO2 system and a bubble counter for the quantitative determination of CO2. The JBL high-performance direct diffuser is available for three hose diameters: 12/16, 16/22 and 19/25.
