Sponge Filter Or Power Filter: Which Is Best For Your Tank?

With there being numerous different types of filtration systems being out there on the market, it can become quite tough for you to find out the best form of filtration system, and how they come up when compared together. For that reason, we have decided to help you choose better when it comes to a sponge filter or power filter.

A sponge filter is a great alternative to the traditional filtration methods if you have a small aquarium in your home. They can replace a hang-on back filter, canister filter or even aquarium sump. If your aquarium is quite low maintenance and has very delicate organisms in it, then the sponge filter can be a great choice.

How Do Sponge Filters Operate?

Sponge filters mainly work based on air pressure, and this is created with the help of an air pump. With the help of some tubing, you can create pressure within the water to ensure the water is driven through to the sponge. This allows for the sponge to do the filtering and also provides enough space for the helpful bacteria to grow as well. What’s great about this method is that not only is it simple, but it will last you for quite some time, only requiring power from electrical outlets or battery operated pumps.

What Is A Power Filter?

Power filtration units are ones that can hang off the back of your aquarium, and of course, use power to operate. They are more extensive in their operation when compared to sponge filters. More so, they live on the basic principle of providing three types of filtration: mechanical, biological and chemical filtration. There are a lot of things separating the good from the best, so it is best to do proper research when you are looking for the best power filter for your aquarium.

  • Mechanical Filtration:

    This form of filtration basically takes in any debris in the water that should not remain in there. It does this by using aquarium mesh or some sponge placed in the filtration system. While it does need to be regularly cleaned and checked on, it is essential for the proper filtration of your tank.


  • Biological Filtration:

    Another very essential component of your filtration system is the biological filtration system. One very common example of this would be ceramic rings. They play a key role in perpetuating the nitrogen cycle within the tank’s ecology, by providing a surface area for the necessary bacteria to grow. This bacteria is very important to ensure the proper growth of the tank’s atmosphere, and they require oxygen to survive. 


  • Chemical Filtration:

    While it is good to have all types of filtration ready to go in your aquarium, chemical filtration does not fall in the category of being necessary at all times. They help in the aesthetics of your tank, in that they clear out some pollutants and excess debris from the water. On top of that, this helps with any discoloration that may be happening in your tank. Activated carbon is a very good example of a chemical filter media.

Types of Filters

While power filters are a very generic term, there are a few different types of filters out there that can be categorized for it. Let’s look into them.

Hang on Back (HoB Filters)

HoB filters are often referred to as power filters in general, and they are also one of the most popular among the general populace of fish hobbyists. They are very easy to use and place on to your setup. They operate with the help of an intake pipe, which drives the water through the filter media and then back out into the tank.

Canister Filters

There is always a debate between which is better, when it comes to canister filters vs HOB filters, but they both have their merits. Canister filters themselves are old-reliable when it comes to filtration systems. They are very efficient and are bound to last you for a long time with proper maintenance. The only burden you could face with them is the fact that they require a bit of prior experience and knowledge for you to be running them smoothly and full potential. However, they provide the benefit of taking care of all three types of filtration discussed, and not having to require as much maintenance as HOB filters.

Sump Filters

Sump filtration systems are much more different than your usual type of filters. They require more knowledge to set up and run, and definitely take more space! One exterior tank takes water from the main aquarium, and runs it through an overflow box with your own customized pipe lining. As you can see from the picture, there are a few different sections, and each of them take care of mechanical, chemical and biological filtration systems.

Sponge Filter or Power Filter?

Now that you know most of the information you’ll need when it comes to deciding on your filtration system, the choice is really yours. Power filters are machines designed to take on larger aquariums and more intricate designs, in order to help your aquarium’s atmosphere and ecology grow properly. However, if you are someone with a small aquarium which requires minimal supervision and cleaning, then a sponge filter really can be all that is needed. 

A question people have a lot is if sponge filters clean the water in a fish tank. Till a certain extent, yes. However, if you’re in need of something that really cleans the water in your tank, then a sponge filter will not be enough. Any of the three types of power filters we have discussed will do a far better job at that. They have different types of filtration setup within the system, and this will allow the machines to take care of your aquarium in a much better way. You should also keep in mind that you will need to clean your aquarium externally as well from time to time, for which there are various types of aquarium vacuum cleaners out there!
