However, if a solenoid valve interrupts the CO2 supply at night or the CO2 supply bottle is empty, the CO2 remaining in the hose will dissolve in the water and aquarium water will continue to migrate into the hose. If it reaches the technical parts such as the solenoid valve or pressure reducer, it can lead to corrosion (rusting) and destroy them. The backflow protection works like a valve that only lets the CO2 gas pass through under pressure in one direction (direction of the arrow on the housing).\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eWhere should it be mounted?\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eIdeally as close as possible to the aquarium water, just above the water level.
