Pump output, filter circulation and maximum flow describe different test conditions. These figures do not establish the flow in your installed aquarium.

Before choosing this model

  • Measure wall and trim clearance.
  • Set flow for the animals and layout rather than using capacity alone.

Read the equipment selection guide alongside these model details. A rated capacity does not settle livestock needs, room conditions or physical clearance.

Choose and care for mechanical, biological and chemical media before buying replacement supplies.
