How to pump water from the fish tank with a hose;
Long pipe pumping water. One end of the length can reach the bottom of the aquarium, and the other end can be connected to the tap water pipe at home. This length of water pipe is called long pipe pumping to pump water from the aquarium. Usage: Connect one end to the tap water pipe, and put the other end into the aquarium water, then turn on the faucet switch and add water to the aquarium. When the water pipe comes out instead of bubbling, the air in the water pipe will be evacuated. At this time, turn off the tap water, pull out the water pipe and put it on the ground to pump water. Note: the height of the bottom of the aquarium is higher than that of the outlet.
