Benefits of Aquarium Sponge Filters

There are several benefits to choosing aquarium sponge filters. These include affordability, simple setup and maintenance, relatively quiet operation, ease of use alongside other filters, and low water movement with high surface agitation. Aquarium sponge filters come in various sizes, which means that they are suitable for different types and sizes of aquariums. Although sponge filters may be the best alternative for smaller tanks, they can still be used for larger tanks also. Aquarium filters are vital to the health of your aquarium.

Sponge Filters for Fish Tanks: The Maintenance Process

Overall, you'll find that sponge filters for fish tanks are easy to maintain. Below are some instructions for the maintenance process:

1. Step one is to remember to regularly perform the maintenance. To clean your sponge, you'll first want to do a water change (saving some of the water that you just removed).

2. Next, you'll want to submerge your sponge in the old aquarium water.

3. Then, you'll squeeze and release your sponge a few times to help get rid of any matter that may clog within the sponge.

Aquarists commonly use multiple sponge filters for fish tanks. Sometimes this is done via two inlets or even by stacking sponges on top of each other. If you have multiple sponges in your fish tank, try staggering your cleaning routine. (Don't clean them all at the same time. Cleaning them at different times helps to lessen the chance of negative impact on biological colonies within the tank. It also helps to reduce ammonia or nitrate spikes following the cleaning.)

Aquarium Sponge FAQs

If you're new to the hobby, you may be wondering why you should get an aquarium sponge(s), how to set up a sponge filter, how to clean it, and more. Use our FAQ section here as a guide to help:

What is a Sponge Filter?

An aquarium sponge filter, as their name implies, is a sponge that draws aquarium water. Drawing aquarium water using a quality sponge provides mechanical filtration. Once the sponge matures and develops bacterial colonies, it also benefits the aquarium by providing biological filtration.

How Does a Sponge Filter Work?

As bubbles in your aquarium water form within the strainer and lift tube, they rise to the top. This forms a gentle current, which in turn, filters water through the sponge. In the early stages of introducing your aquarium sponge filter to your tank, expect it to only provide mechanical filtration. With time, you'll find that good bacteria will colonize your sponge filter. This means that over time, you'll also reap the benefits of biological filtration for your tank.

How to Set Up a Sponge Filter?

The process for how to set up sponge filters is relatively easy. Follow the steps below:

1. Remove your sponge filter(s) from the packaging and spread everything out on the table so that you can ensure you have all the parts you need. This is helpful in case you happen to have a missing piece.

2. Next, detach the bullseye (at the base of your strainer) and replace it with an airstone. Next, connect your airstone to the bullseye's center using airline tubing.

3. Now you will want to attach the bullseye to your strainer again. Put the strainer back into the foam.

4. You'll now want to take the lift tube from one end of the airline tubing and securely attach it to the center on top of the bullseye. Make sure it is secure before using the filter.

5. Now that your sponge filter is fully assembled, dip it into the aquarium water. Squeeze out any air bubbles which may be trapped inside the foam.

6. The next step is connecting your air pump to your new sponge filter. If necessary, you may need to install a check valve to prevent any possible backflow. If you have questions, be sure to discuss with a professional aquarist.

7. Finally, add a drip loop to the power cable that is powering your air pump. (This prevents moisture from reaching your power cable.) Once the drip loop is added, you can now turn on your air pump. Watch for bubbles coming from your sponge filter. This means you have completed a successful setup!

How to Clean a Sponge Filter?

Sponge filters are easy to clean. Below are some steps to follow for how to clean a sponge filter:

1. To clean your sponge, you'll first want to perform a water change. Be sure to save some of your current aquarium water.

2. Next, submerge your sponge in the existing aquarium water.

3. Finally, squeeze and release your sponge several times to remove anything that has clogged inside of the sponge.

Note: you'll want to regularly clean your sponge filters. If you have multiple filters, don't clean them at the same time as that may result in a spike of ammonia or nitrates.
