If you want to keep fish, you will need a good aquarium.
However, when getting an aquarium, you will need to consider the type of filter you will need to use—different aquarium filters, including sponge filters, canister filters, fluidized bed filters, etc.
So, while you should consider the different types of filters when buying an aquarium, don’t forget to note the various factors.
Are you in a hurry? Take a quick glance at my top recommendations for the Best 10 Gallon Fish Tank Filters:
These factors may include bio-media capacity and the different types of filtrations, such as mechanical, chemical, and bacterial filtration.
However, what is bio-media capacity in the first place? More importantly, how much bio media will you need for your aquarium?
Many people look for their bio-media capacity when it comes to aquarium filters. Biomedia is a natural way to clean the water contained in the aquarium, and it is one of the safest media that you can use to clean your aquarium.
Biomedia removes the ammonia and nitrate from the water and helps reduce the biological nitrate formation. The substance comes in the form of balls, and you will need at least 10 liters of bio balls for every 450 liters of water.
Bio balls have a large surface area consisting of grooves on which bacteria cling. They work by eliminating the bacteria in the water and balancing the Ph levels to neutral. Although you may need to clean them, they are easy to maintain, especially after use.
In general, the filtration process of most aquariums consists of three stages, including mechanical filtration, chemical filtration, and bacterial filtration.
So, when buying an aquarium, you should also check if it comes with mechanical filtration. Mechanical filtration is used to clear out all the debris settling down at the aquarium’s bottom.
Most aquarium filters use sponges, filter socks, and floss pads for this process. Together, they can filter out much of the debris that has sunk into the bottom of the water.
However, remember that mechanical filtration only removes the trash, and you must still clean the filter media. The filter media or ‘bag’ collects the garbage, and you must get rid of it by emptying the bag.
Chemical filtration, like mechanical filtration, is another process that uses activated carbon or resins to rid your aquarium of medications, tannins, and other harmful chemicals.
However, unlike in mechanical filtration, the filter media becomes full and unusable once the process completes. So, you cannot reuse the filter media.
There are many species of aquatic bacteria, both good and bad.
However, when it comes to aquarium filters, such organisms flush out the bad bacteria and other harmful substances present in the water in two ways. First, the bacteria convert the toxic ammonia into nitrite.
Then, a second species convert the nitrite into nitrate. Since these bacteria help convert the nitrite into nitrate, they are commonly known as ‘nitrifying bacteria.’
However, that’s not all that the bacteria present in these filters do. You also have a third type of bacteria that converts nitrate into nitrogen and let it out into the atmosphere. So, bacterial filtration of aquarium water is a three-step process.
The first set of bacteria converts toxic ammonia into nitrite, and a second set help converts this nitrite into nitrate. Finally, the third set of bacteria convert this nitrite into nitrogen and let it out into the atmosphere.
The Need for Biomedia Filters
Biomedia filters can help clean the water present in an aquarium, and they do this using the three filtration methods discussed above.
However, there are other advantages of using bio-media filters in your aquarium.
- These filters help maintain low ammonia and nitrite levels in the water, which can be good, especially if you have many fish species.
- Moreover, bio-media filters benefit many types of fish, including goldfish and cichlids. They do this by balancing the ammonium levels in the water, and ammonia is a major food source for fish.
- However, natural aquariums having fewer fish may not need too many bio-media filters.

Which 10 Gallon Filter is Best?
Now that we have gone through the best tank filters on the market, now is the time to decide what filter would work perfectly with your tank. The decision depends on several variables, such as your tank and fish size.
Whereas some filters have specific capacities, many come with a more extensive range that gives a certain sense of flexibility regarding using the same unit for future tanks that might be smaller or bigger than the current one.
However, as you are looking specifically for the best 10-gallon filter, the size and capacity of the filter should not confuse you.
Another critical issue that often comes up is the safety of the fish. Most of these filters have a history of hurting the smaller fish. So you better look for tanks explicitly made for smaller fish or tanks that feature various safety instruments attached to them.
When it comes to safety, we highly recommend The Aquanet Sponge Filter as it might be an excellent addition to your tank when the concern of safety is involved.
Most of these filters use pumps to work effectively. You may select from the top brands and units that have shown excellence in providing cost and energy-effective units.
However, sound becomes a more significant issue for these filters. Tetra Whisper IQ Power Filter would be great if you are looking for a quieter option.
Finally, although all these models have unique benefits, you can rely on any product mentioned on our list. Most of them provide a healthy and clean environment for your fish, clean the chemical toxins and provide adjustable water flow in the tank.
So, when buying an aquarium, remember to look at the type and number of filters you may need. If you plan to have a wide range of fish in your aquarium, you may need more filters.
However, these three filter mechanisms should suffice if that’s not the case. Also, while buying a filter for your aquarium can be helpful, especially for cleaning, don’t forget to clean them.
The design of these filters is such that they can remove bacteria and other pollutants from the water present in the aquarium.
However, it would be best to clean them still to get the bacteria and dirt out for good. Also, be sure to add 10 liters of the bio-media filter for every 450 liters of water to rest assured that your aquarium is clean.
