Possible Correction

1. Motor runs but does not pump water.

• Check for air trapped in pump housing - Check for broken impeller or bag insert not in properly.

2. Filter powders continue to come through into the aquarium.

• Bag insert not properly in place - check filter bag

3. Filter powder do not coat evenly and water flow is not good.

• Bag is plugged where powders do not coat - remove and clean or replace.

4. Intake hose collapses.

• Check for plugged or restricted slot in intake strainer.

5. Algae growing in filter jar and on bag.

• Place filter in dark area or cover with something to eliminate light

6. Motor noisy and air coming out exhaust hose - flow good.

• Check impeller for gravel or other cause.
• Check intake hose and fitting for air leaks.

7. Water leak at exhaust "U"-tube.

• Check hose clamps and "U"-tube for casting lines.

8. Water hazy or smoky - filter flow is good but aquarium will not clear. All things check O.K. Fish act fine.

• Probably a bacteria or amoeba form of life - usually after new water is put into the aquarium - and is too small for the filter to take out. Condition will correct itself in a few days.

9. Air collects in pump housing and breaks pump prime.

• Exhaust hose does not lead off in an upward angle to eliminate air from system - keep intake downspout away from air stones and bubblers
• Disconnect from power momentarily and allow the air to escape.

10. Water leaks from around jar top area.

• "O"-ring has filter powder or part of the filter bag under it - remove, clean and lubricate with silicone grease or vasoline before reinstalling. Be sure filter bag clears jar mouth and seal.
