The UPETTOOLS Aquarium Biochemical Sponge Filter is on top of our list because it has a huge number of benefits for your aquarium or fishbowl! This filter can easily be moved around so you can use it with different types of tanks, and the adjustable tube height makes it even more functional!

  • Tank capacity: 10.5 gal.
  • Flow rate: 9 GPH
  • Dimensions: 3.07 x 2.48 x 2.4 inch
  • Weight: 3.2 oz.

More features: noiseless

The SunGrow 10-Gallon Betta Sponge Filter is a noiseless filter is designed for betta fish tanks that are up to 10 gallons in size. It works by drawing water into the intake tube, then through the sponge inside, where beneficial bacteria break down harmful toxins via biological filtration. Finally, clean water flows back into your tank with one quick squeeze of the handle on the outside of the filter housing. So it’s a great filter due to its small size, low price, and high-quality operation.

This aquarium filter is one of the smallest on this list. It is only comparable in size to the Aqueon QuietFlow power filter, Best for 3-Gallon Betta Tank. Still, the SunGrow 10-Gallon Betta Sponge Filter has a slightly higher capacity as it can handle a 10.5-gallon tank compared to the Aqueon Quietflow, which can only be used for a 3-gallon tank.

What makes it stand out?

Best for Large Betta Tank

Insputer Submersible Water Pump Filter

Features
  • Filter type: pump filter
  • Tank capacity: 25 gal.
  • Flow rate: 21 GPH
  • Dimensions: 9.13 x 3.31 x 2.05 inch
  • Weight: 13.4 oz.

More features: low-noise design, suitable for fresh and saltwater

As the name suggests, the Insputer Submersible Water Pump Filter sits below the water line and draws in dirty water from below to pass through a filter cartridge and pump the clean water out of a tube in the top. The multiple flosses and sponge layers allow you to create different flow rates and filtration combinations. This is a good betta tank filter because it can produce a higher flow rate than some other filters and is suitable for huge capacities.

This submersible filter is the only pump filter in this review, which is quite unique. In terms of output, it is similar to the UPETTOOLS Aquarium Biochemical Filter, the Editor’s choice, which has a slightly higher flow rate. However, this unit is smaller (about the size of a soda can) and weighs less compared to the UPETTOOLS filter.

Why is it special?

  • This filter features an anti-cycle design which will help prevent the filter from opening up during filtration resulting in less maintenance needed for your betta fish or other aquatic animals
  • It has a higher flow rate than many other betta tank filters, and therefore even if you have to run more than one of these filters on your tank, they will not greatly decrease the water volume
  • It is about the size of a soda can and weighs only 1/4 lb., making it small enough to put inside of betta tank without needing an additional container for it
  • It has no installation requirements

What are the flaws?

  • If you have a tank with gravel on the bottom or try to use this filter in a smaller tank, there's a chance that it could suck up gravel with the water
  • It is not suitable for large tanks

Where they differ is in how they operate and the size of the aquarium you can use them for. With the Penn-Plax, you can only manage a 7-gallon tank.

Things to Consider

Keeping your betta tank clean is important for their health, but not everyone has the time or patience to maintain a large aquarium. If you want to give your betta or other fish healthy water without all the effort of maintaining an aquarium, it’s best to invest in one of the best filters for betta tanks listed in this guide.

How to Pick the Best Filter for Betta Tank

Using the right filter is an important part of keeping your betta tank clean and healthy, but it’s not always easy to choose which type you should buy. Some filters work best in smaller tanks, while others aren’t as good with smaller fish like betta. It’s best to familiarize yourself with what each filter can and can’t do for your tank before you make a purchase.

Filter Type

There are several different types of filters you can choose for your betta tank, but the best one will vary from person to person. Some people prefer a sponge or bag filter because it’s easy to maintain and won’t produce as much noise as a HOB filter. Others might prefer an external filter since it has a lot more filtration power and can handle larger tanks. Your tank size and betta’s needs will determine what kind of filter you should get for your fish.

Here are some of the most common types of aquarium filters available:

Canister Filter

7 Best Filters for Betta Tanks – Keep Your Betta Healthy and Happy (Fall 2022)

Unlike power filters, the loss of water in the canister filter is far less or close to zero, and also it is one of the major benefits of using it.

Canister filters clean water by trapping debris inside a filter cartridge. As the aquarium’s water runs through the canister, it pulls in dirty particles that attach themselves to the filter material. The canister itself is completely hidden under your fish tank and rests on the back of your tank. This makes it one of the best options for any betta fish tank, giving you a quiet environment that won’t stress out your fish with excess noise. The included BioMax insert provides balanced biological filtration as well as the mechanical and chemical filtration you would expect from a quality 3-stage filter. For more info, you may check the guide with the best canister filters for more powerful cleaning.

Internal Filter

7 Best Filters for Betta Tanks – Keep Your Betta Healthy and Happy (Fall 2022)

These models are good for smaller aquariums. They don’t create a ton of water flow, but they do create the right environment for smaller fish that like still waters.

Internal filters are another great option for betta tanks because they’re very quiet and easy to maintain. Internal filters work by pulling water through the filter media, usually sponges or other porous material, which traps dirty particles as the aquarium’s water passes through it. Some internal filters also include bio-balls which can provide mechanical filtration for betta tanks while also providing a safe environment for the bacteria that break down waste. Additionally, the best internal aquarium filter can be a great alternative to HOB or canister filter.

Sponge Filter

7 Best Filters for Betta Tanks – Keep Your Betta Healthy and Happy (Fall 2022)

Sponge filters work well as a pre-filter on the inlet of a canister filter. The sponge filters out a good deal of the larger particulate matter, which keeps the canister from clogging.

A sponge filter is another common type of HOB filter used in betta fish tanks because it’s easy to maintain and provides balanced biological filtration. The internal opening lets water flow into the sponge, where bacteria, as well as trapped particles, clean it. Because this filter doesn’t take up much space, it’s best to use in smaller betta tanks where there isn’t much room for other types of HOB filters. This makes it one of the best options for any betta fish tank, giving you a quiet environment that won’t stress out your fish with excess noise.

Hang On The Back or HOB Filter

7 Best Filters for Betta Tanks – Keep Your Betta Healthy and Happy (Fall 2022)

HOB filters are an excellent way to keep your tank water clear and reduce harmful and potentially deadly chemicals that otherwise build up in your aquarium. They’re often cheaper than sump pumps and canister filters, they’re super simple to set up, and they’re typically a breeze to clean.

HOB, or hang-on-back filters, are one of the most commonly used types of filter for betta tanks. These filters attach to the back of your fish tank to provide filtration as the aquarium’s water passes through it. The best HOB filters for any betta tank is in our guide because they all provide both biological and mechanical filtration as well as being very quiet. This makes it one of the best options for any betta fish tank, giving you a quiet environment that won’t stress out your fish with excess noise.

Flow Rate

Flow rate is a very important factor to consider when choosing a filter for your betta tank. The flow rate will determine how powerful the filtration is, as well as how much sound you’ll have to deal with from your fish tank’s filter. The best betta filters have a low flow rate so that they won’t disturb the fish but provide high filtration power for cleaner water. The best betta tank filter should have a flow rate of 30-50 gallons per hour, which will work perfectly in any small to a medium-sized aquarium.

Tank Size

Tank size is another important factor to consider when choosing a filter for your betta tank. The best betta filters are the ones that are sized properly for the tank you have, otherwise, there could be too much or not enough filtration power. For example, if you have a 10-gallon aquarium, it’s best to get a filter designed for 10 gallons or less. If you have a smaller aquarium, then it’s best to use sponge filters or other types that can fit in smaller spaces.

Multiple Filtration Stages

You should always choose a filter with multiple filtration stages because the more filtration power you have, the cleaner your betta’s water will be. The best betta fish tank filters are those that provide strong mechanical and biological filtration while also providing chemical filtration to keep ammonia at zero parts per million. The best betta fish tank filters also come with activated carbon and other types of media, which can be changed to maintain the filter’s performance.

Ease of Maintenance

Maintenance is an important factor to consider when choosing a filter for your betta tank because incorrect maintenance can cause serious damage to your fish and the environment they live in. You should always make sure you know how often you need to clean or change the media and parts of your filter before setting it up, as well as what type of maintenance schedule works best with this type of filter. These factors will vary depending on the types of media used and their sizes, but most filters will require weekly changes or replacements.

Size and Weight

Size and weight are both important factors to consider when choosing a filter for your betta tank because you’ll have to make sure that the filter is sized properly and that it won’t be too heavy for the aquarium. The best betta tank filters will weigh less than a pound, so they can easily be placed on the bottom of any 10-gallon or smaller aquarium without adding too much extra weight. You should also choose a filter with compact dimensions, so it fits easily in small spaces, as well as being light enough to lift out from the fish tank if needed.

More Features

There are many other features you should consider when choosing a filter for your betta tank because some types of filters offer different conveniences that can make life much easier. For example, the best betta fish tank filters will come with hoses and another tubing, so they’re ready to use without requiring any extra purchases. Many also have suction cups for easy installation on the glass and carbon cartridge slots, so you don’t have to worry about replacing these parts yourself.

FAQ

Sponge filters and other small options are always best. If you have a larger tank, make sure to use an appropriate filter with multiple filtration stages that can remove ammonia from the water.

It’s important to clean both your filter as well as the inside of your betta tank on a weekly basis. By doing this, you can ensure that there is no filtration blockage and that all parts of the aquarium are kept in top condition.

Our Verdict

When choosing a filter for your betta tank, it’s important to consider all of these factors mentioned before so you can provide the best environment for your fish. In order to keep your betta healthy and happy, always choose a filter with low flow rates, multiple filtration stages, the right size, and weight, as well as conveniences like hoses and tubing that make maintenance easier. The seven best filters for betta tanks should provide all of these features to ensure your betta has the best possible environment to thrive in.
