1.Note: Must be completely submersed under water and clean it regularly in case the pump makes noises or stops working due to debris blockage. 2.The inner shaft will be with a little bit of lubricant to ensure the motor is working well, If you are raising sensitive fish or aquatic plants, please use them in other tanks for a short time then move it into fish tanks. 3.Due to all the pumps need professional water testing by our manufacturer before shipment, if the water pump you received has a little water left from the testing, it is a normal phenomenon.
