TROUBLE SHOOTING
Problem: The skimmer is not removing any waste
1. Possible Cause: Water level is too low or skimmer is positioned in water that is too shallow.
Solution: Alter water level adjustment dial accordingly or raise skimmer in sump.
2. Possible Cause: Air line, venturi or needlewheel impeller is blocked.
Solution: Remove and check for blockage and clean as required.
3. Possible Cause: Pump is not plugged in or is not operating correctly.
Solution: See pump section below
4. Possible Cause: The skimmer has not bedded in yet or the aquarium is too new to produce
enough organic waste to be removed.
Solution: Allow more time for the skimmer to bed in and the tank to mature.
Problem: Skimmer water level fluctuates
1. Possible Cause: Evaporation causing level changes in the sump.
Solution: Install a REEF-Fill Auto Top Up System or similar, to ensure stable levels.
2. Possible Cause: Pump, venturi and needlewheel impeller may be blocked.
Solution: Check that the pump, venturi and impeller are free from detritus.
Problem: Pump is not operating correctly
Caution:
Always isolate the pump from mains electricity before installing or carrying out any
maintenance to the pump and refer to the pump operation, maintenance and safety
instructions supplied with the pump.
1. Possible Cause: Pump is not plugged in.
Solution: Ensure pump is connected to power supply and switched on.
2. Possible Cause: Pump is blocked with dirt and debris.
Solution: Clean the pump to remove dirt and debris (refer to pump instructions for full
maintenance instructions).
Problem: No air bubbles (or very few) are being produced inside the skimmer
1. Possible Cause: The air line to the venturi is not attached.
Solution: Re-attach the air line to the venturi.
2. Possible Cause: The air inlet of the venturi or needlewheel impeller is blocked.
Solution: Remove and check for blockage and clean as required.
3. Possible Cause: Pump is not operating or performing correctly.
Solution: See pump section above.
Problem: No foam is being produced inside the collection cup
1. Possible Cause: Water level inside the chamber needs to be adjusted.
Solution: Alter water level adjustment dial accordingly.
2. Possible Cause: Skimmer has just been installed and may take up to 24hrs to adjust
properly to the aquarium system.
Solution: Let the pump run for 24-48 hours to allow the skimmer to establish itself before
making any adjustments.
Problem: Water is rapidly overflowing into the collection cup
1. Possible Cause: Water level may be too high or skimmer is positioned in water that is too deep.
Solution: Alter water level adjustment dial accordingly or reduce water level in the sump.
2. Possible Cause: Water is not being discharged through the outlet pipe assembly.
Solution: Remove and check for blockage and clean water outlet assembly as required.
