We recommend placing the pump in a reasonable working area: the shallowest of the horizontal plane is 10 cm and the deepest is 50 cm. 2.It makes a loud noise when pumping. The reason may be that the fish food is blocking the water connection of the pump and it must be removed and cleaned immediately to avoid burning out the motor.
