AQUEON - QuietFlow 55/75 Power Filter - 400 Gph

Product Description

Aqueon QuietFlow Power Filters and cartridges were designed with the fish and the aquarist in mind. Our patented designs include unique features to enhance water quality and clarity, increase oxygen levels and lessen noise.

Aqueon QuietFlow™ Power Filters feature four stages of filtration–mechanical, chemical, biological and wet/dry–for the cleanest, clearest, healthiest water. Higher flow rates ensure higher dissolved oxygen content for healthier, more active fish. The internal pump design helps dampen noise, eliminates leaks and starts up automatically after cleaning or power interruptions.

Four Stage Advanced Filtration System

Stage 1 - Dense floss removes particles and debris.
Stage 2 - Activated carbon removes toxins, odors and discoloration.
Stage 3 - Patented Bio-Holster removes toxic ammonia and nitrites.
Stage 4 - Diffuser grid removes additional toxins while adding oxygen for more active fish. It also reduces splashing makes the return exceptionally quiet.

  1. Check pump for any signs of shipping damage. If damaged, do not operate and return to place of purchase.
  2. Insert suction cups into pump mounting bracket.
  3. Slide mounting bracket onto base of pump.
  4. Insert O-ring onto threaded filter connection. Screw desired connector into outlet of pump. Hand tighten only.
  5. Connect tubing or PVC pipe to outlet of pump and place inside sump or aquarium.
  6. Fill sump so that water level is above the top of the pump. Always make sure pump is completely submerged when operating. Do not run pump dry.

To guard against injury, basic safety precautions should be observed, including the following:

  1. Read and follow all safety instructions.
  2. Danger - to avoid possible electric shock, special care should be taken since water is employed in the use of aquarium equipment. For each of the following situations, do not attempt repairs by yourself; return the appliance to an authorized service facility for service or discard the appliance.
    1. If the appliance shows any signs of abnormal water leakage, immediately unplug it from the power source.
    2. Carefully examine the appliance after installation. It should not be plugged in if there is water on parts not intended to be wet.
    3. Do not operate any appliance if it has a damaged cord or plug, or if it is malfunctioning or has been dropped or damaged in any manner.
    4. To avoid the possibility of the pump plug or receptacle getting wet, position aquarium stand and tank to one side of a wall mounted receptacle to prevent water from dripping onto the receptacle or plug. A "drip loop" (illustration shown in instruction manual), should be ararnged by the user for each cord connecting an aquarium appliance to a receptacle. The "drip loop" is that part of the cord below the level of the receptacle, or the connector if an extension cord is used, to prevent water from traveling along the cord and coming in contact with the receptacle. NOTE: if the plug or receptacle does get wet, DON’T unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the appliance. Then, unplug and examine for presence of water in the receptacle.
  3. Close supervision is necessary when any appliace is used by or near children.
  4. To avoid injury, do not contact moving parts or hot parts such as heaters, reflectors, lamp bulbs, and the like.
  5. Always unplug an appliance from an outlet when not in use, before putting on or taking off parts, and before cleaning. Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.
  6. Do not use an appliance for other than intended use. The use of attachments not recommended or sold by the appliance manufacturer may cause an unsafe condition.
  7. Do not install or store the appliance where it will be exposed to the weather or to temperatures below freezing.
  8. Make sure an appliance mounted on a tank is securely installed before operating it.
  9. Read and observe all the important notices on the appliance.
  10. If an extension cord is necessary, a cord with a proper rating should be used. A cord rated for less amperes or watts than the appliance may overheat. Care should be taken to arrange the cord so that it will not be tripped over or pulled.
  11. This appliance has a grounded plug. As a safety feature, this plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Never use with an extension cord unless plug can be fully inserted. Do not attempt to defeat this safety feature.
  12. Save the printed instructions that come with this product.
