How to Set Up a Fish Tank Air Pump

The bubbles that air pumps generate in a fish tank serve two main functions: to work with aerators to help oxygenate the water, and to work with filters by moving water through in-tank filtration systems. A side effect of the bubbles is they provide interest and stimulate activity within the aquarium. Air pumps come in various sizes, shapes and output capacity, with some newer brands specifically designed to emit minimal noise and vibration. Whatever type of air pump you choose, setting it up for a fish tank is essentially the same.

Instructions

  1. Setup Instructions

    • 1

      Test the air pump. Before attaching the pump to any filters or aerators, plug it into an electrical outlet to check if it works. Read the instructions for any warnings or special tips for setting up the air pump.

    • 2

      Measure the plastic tubing. The tubing delivers the air from the pump to the filters and aerators. Determine the designated locations of the tank filters and aerators relative to where you will situate the air pump. Note that the longer the tubing, the weaker the air pressure at the end of the tubing.

    • 3

      Connect the plastic tubing to the air pump and to the tank's filters or aerators. Connect the tubing securely to prevent leaks.

    • 4

      Attach accessories as needed. You might need connectors to attach tubing to filtration systems, valves to control the air pressure or junctions to attach more than one aerator to the main tube. Use clamps or suction cups to secure tubing to the tank walls.

    • 5

      Turn on the air pump. Note the strength of the flow of bubbles and adjust as necessary with valves or adjustable clamps.
