Installation Tips
In-line Pump:

  • Using an in-line pump with a wet/dry filtration system: Water flows via gravity from the aquarium into the wet/dry filter, and then into the filter's sump. From the sump, it flows into the pump via gravity through a bulkhead installed in the side of the sump. The pump sends water back up into aquarium from the wet/dry filter's sump. When installing pumps with wet/dry filtration, you'll need to drill into the filter's sump to install the bulkhead, then mount the pump level to the bottom of the filter's sump.
  • Using an in-line pump with canister filtration: Water moves via gravity from the aquarium into the pump. The pump pushes the water through the canister filters, and back up into the aquarium (or UV filter, chiller, etc.). You need to siphon water from the aquarium and flood the pump before turning it on.
  • Never restrict the inlet flow of any water pump. This will quickly cause permanent motor damage.
  • You can restrict the outlet flow of the water pump with a ball valve in order to achieve the desired flow rate.
  • Use ball valves before inlet and after outlet to make pump removal easy and spill free.
  • Anytime a threaded connection is used, be sure to use Teflon tape. When using barb insert connections to flexible tubing, use hose clamps. (Plastic hose clamps are required for underwater use.)

Submerged Pump:

  • Set your submersible pump on suction cups at the bottom of your sump. This will help reduce vibration and noise.
  • Be sure to completely submerge the pump before connecting it to a power source.
  • Try not to place the submerged pump's inlet near the output of the protein skimmer, if you have one installed. A skimmer can sometimes produce air bubbles in the exhaust water, and these bubbles can be sucked up by the pump and returned to the aquarium. These bubbles are undesirable inside an aquarium, especially a reef aquarium.

Maintenance Tips
All water pumps benefit from a regular cleaning. Check the manufacturer's instructions as to how often maintenance should be performed on your particular pump.

Basic Cleaning Steps:

  1. Remove the pump from the system.
  2. Remove filter from the front of submerged pumps 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 them 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.

    Other Cleaning Tips:

    • 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.
    • If you have lime or mineral buildup on any part of your pump, you can dissolve these with Lime Off, which is especially designed for removing lime, salt residue, and other hard deposits on aquarium equipment. Make sure to rinse thoroughly with fresh clean water before reassembling your pump.
