Use the exact nameplate watts and your real schedule in the aquarium electricity cost calculator. Leave an unpublished wattage blank.

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

  • Confirm model 78001.
  • Do not treat the 130 GPH maximum as in-tank turnover after media and head losses.

Still to confirm

  • A gallon rating and body dimensions are unresolved. For a purchase based on tank size or tight rear clearance, use a model with documented limits or inspect this exact package before deciding.
  • Read watts from the exact unit label before calculating electricity; do not enter an unknown load as zero.

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.
