Frequently Asked Questions

Can you use a regular sponge as an aquarium filter?

Aquarium owners can use regular sponges as a filter but must be careful. Researching your particular sponge is essential to see if it’s usable. Otherwise, they may contain chemicals that poison the tank and kill your fish.

But honestly, I would suggest avoiding this situation entirely. Instead, a traditional sponge filter for fish tank use is much better, such as Aquaneat’s Aquarium Bio Sponge Filter. This model has been an excellent option inside my tank for years.

How can you make your sponge filter quieter?

Many aquarium owners with sponge filters complain about their noise levels. The issue was a pain when I first installed my large sponge filter. But I was able to solve the problem by learning how to limit the noise:

• Adding a valve on the air pump: Valves are valuable for limiting noise on these sponge filters. After all, they lower the stream and air pressure, which reduces how much is being pulled into your filter. So the sponge filter air pump ends up making much less noise.
• Placing the air pump on a mat: Moving your air pump to an area with padding can help reduce the noise by limiting vibrations.
• Putting a lid on your aquarium: The simplest solution is placing a cover on top of your aquarium if it doesn’t have one. Doing so will trap the noise inside your tank rather than haunting your sleeping sessions.
• Buying an option with a reputation for being silent: Some sponge filters do better at limiting their noise level. So if none of these methods work, look into “silent” options and research them thoroughly. I suggest looking on Reddit or through customer reviews to understand better which ones are less noisy.

Are sponge filters safe for small fish?

Sponge filters are a safe option for small fish. Most experts even recommend using them because they’re safer than other alternatives. Sponge filters offer this benefit by ensuring the smallest fish or shrimp can’t get sucked into them. Plus, they provide a gentler flow to ensure it’s not too rough for a smaller species.

As a result, owners with smaller fish or other creatures would do well with a sponge filter. I’d only advise reading through the description before making a decision. It’s a precaution to ensure your chosen model is meant for axolotl, goldfish, or other aquatic creatures.

What are the most trusted aquarium sponge filter brands?

When you start your search about various sponge filter brands, it can be overwhelming to see innumerable options for you to check out; be that as it may, not all of these are functional and reliable. And, to help you narrow down your choices, the most trusted brands are the following:

• Aquaneat

Sponge filter vs. Power filter: What is the difference?

A sponge filter is typically made of permeable spongy material as well as an air tube which is employed as the filtering mechanism. More than that, it can be exploited to provide bio and mechanical filtration of solid particulates, byproducts and other tank debris. This does not provide any kind of chemical filtration though.

On the other hand, power filters are generally hung off the back of the tank and it works by drawing water in with the aid of a lift tube and then going back by means of a spill-way. It comes with a water pump to maneuver the water.

Can I use these filters for a turtle tank?

In order to provide the proper maintenance for a turtle tank, canister filters are better options than sponge filter. This is because turtle tanks require bio, chemical and mechanical filtration mechanisms. And, as previously mentioned, sponge filters aren’t capable of providing chemical filtration.

How to set up a sponge filter?

Materials you will need:

• Air pump rated for the current size of the tank that you are keeping
• Top quality air stone
• Sponge filter
• Check valve
• 3/16” fish tank airline tubing

Procedure:

1. Take the sponge filter apart. You need to prepare a weighted base at the bottom, foam sponge, and a lift tube. There must be a strainer inside the sponge and the bull’s eye on top of the strainer.
2. An airstone is practical to use inside the sponge filter. This helps make the bubble tinier and more silent. The strainer should be in a hollow shape making it smooth sailing to build up the airstone.
3. Re-assemble other components of the sponge filter. Then, embed the strainer within the sponge and then fasten the weighted base to the strainer’s bottom section. Afterward, link the lift tube onto the top of the bull’s eye. See to it that the sponge filter is fastened to the lengthy roll of the airline tubing.
4. Put the sponge filter into the tank and gently squeeze it a number of times to eliminate most of the bubbles. It must sink instantly; however, even if it does not, it will sooner or later get the water set down enough that it remains down. Squeeze a new sponge filter many times to enable it to drop the bubbles.
5. Set up the air pump. Place it where you plan it to stay and cut the airline tubing so that it is lengthy enough to link the sponge filter to the air pump. After that, you can link the newly cut airline tubing’s end to the spout on the air pump.
6. In case the air pump is underneath the sponge, cut the airline tubing a few centimeters on the external section of the tank and link the check valve in between. Here, it is important to ensure that the banded side of the check valve maneuvers toward the pump. To check if it was properly set up backward, there should be no air that could enter the sponge filter.
7. Finally, plug in the pump. It is a must to carefully inspect if there is a drip loop in the power cable. The purpose of this is to ensure that no amount of water can come to the outlet.

At this rate, there should be generous bubbles hovering to the surface, observe if it is working properly in terms of clearing the tank of any debris and must be capable of intruding any surface impurities. This way, your good bacteria will have a great hub where they could healthily thrive and reproduce.

How to care & clean?

Generally, it is indispensable to clean the sponge every 2 weeks. Nonetheless, hinging on the type of sponge you’re utilizing as well as the bioload in your tank, cleaning the sponge more often is specifically vital to consider.

When the water surrounding the sponge media starts to slow, this is already a clear indication that it is high time to clean the sponge. When removing the sponge, it is necessary to put a tiny bowl or container underneath the sponge as you take it off the tank.

Essentially, this will aid in inhibiting filthy water and residues from drawing back into the tank as you lift it off the filter. At the time the filter has been lifted off, you only have to fill up a tiny container with some used tank water. Afterward, put the sponge into the container and give it some squeezes till nothing transpires from the sponge.

Put the sponge back in the tank, discard the filthy water in the container and then add new conditioned water as required.

What is the warranty?

When it comes to product warranties, highly trusted brands offer different forms of warranties to their most valued customers; on the other hand, new manufacturers may offer limited warranties or no warranties at all. Hence, it is advised to stay away from manufacturers who sell products that are not supported by warranties.

Warranties come in different forms, so it is essential to check this as it may vary from one manufacturer to another. In general, warranties provided include a 3-year warranty, replacement parts or refunds.
