Water pumps play an integral role in the aquarium. The water movement they provide is critical for proper gas exchange, supplemental filtration, and for creating a natural environment that benefits the mental and physical well-being of your aquarium inhabitants. Like most aquarium equipment, water pumps can occasionally require cleaning. Keeping your water pumps clean and functioning properly will reduce expenses by extending their performance.
2. Remove filter from the front of submerged pump and remove debris. Rinse with plain fresh water (no soap).
3. Remove the impeller housing cover to expose the impeller.
4. Remove the impeller and the magnet. Inspect for damage and wash with plain fresh water (no soap or abrasives).
5. Wash out the impeller housing with plain fresh water (no soap or abrasives).
6. Reassemble the pump and re-install it in your system.
Some brands of in-line pumps require periodic oiling to lubricate the motor. Always refer to your owner's manual for instructions on this procedure.
Routine maintenance helps protect your equipment investments, but be sure to check the manufacturer's instructions as to how often maintenance should be performed on your particular pump.
