How to Set Up an Aquarium Sponge Filter

In order for a closed environment like an aquarium to work properly, it is important to have sufficient filtration in place. Fish tanks need to have biological, chemical and mechanical filtration in place to break down and remove fish waste, uneaten food and other contaminants. Sponge filters, which provide all three forms of filtration, can be a good choice for aquarium owners.

Instructions

    • 1

      Decide where you will place the sponge filter in the aquarium. A back corner of the aquarium generally works best.

    • 2

      Attach a piece of plastic tubing to the tube on the sponge filter. Make sure the plastic tubing fits securely over the tube. Use a pencil to widen the plastic tubing slightly if necessary.

      Attach the other end of the plastic tubing to the input on your aquarium pump. Place the sponge filter in the corner of your aquarium, wringing the sponge out as you move it toward the bottom of the tank. This will dissipate any air bubbles and prevent the sponge filter from floating to the top.

      Place an assortment of real or artificial plants in front of the sponge filter to hide it (one downside of sponge filters is that they tend to be unattractive).
