I can&;t. The principle is different.
The gas stone is injected into the gas stone through the hose by the air pump, and then the gas stone refines the air through the hole and inflates it into the water body. The principle of the three-in-one water pump is just the opposite. A hose extending out of the water is connected at the water outlet of the water pump. When the water pump is turned on, the water flows through the water outlet to drive the air in the hose to flow and combine with the water flow to pump the air from the outside to the inside of the cylinder. Therefore, the three-in-one water pump can&;t add oxygen-increasing stone.
