Why does water flow back into CO2 hoses?
CO2 has a strong desire to dissolve in water, so to speak. If the CO2 supply to the aquarium is interrupted (CO2 cylinder empty, cylinder valve closed, CO2 night switch-off activated, etc.), the CO2 still in the hose also dissolves in the aquarium water. This creates a vacuum in the CO2 hose, which sucks the aquarium water into the hose. The DENNERLE CO2 special backflow protection protects valuable CO2 equipment such as pressure regulators, CO2 cylinders, CO2 night shut-off, etc. from damage caused by backflowing water.
