firstly, the water source is drained to a high place to form a high water source, and then the water flow from the high water source is drained to the rockery at a lower position through the drainage pipe, and then flows down into the reservoir through the water outlet on the rockery, thus forming a landscape of "flowing water in the mountains". When people need to send the water in the reservoir to the water storage device at the high place of the house, they must use a water pump, and it will take a long time for people to pump the water after the water pump fills the water storage device at one time.
The so-called unpowered water circulation means that the water in the fish tank is sucked out by siphoning, and the sucked water will flow into a clean basin, and a layer of cloth can be placed on the basin, which can play a role in filtering omnivores and dirty things. After inhaling some water, you can stop and slowly pour the water in the basin into the tank.
