A filter is the heart of every aquarium and also a great way to keep fish happy and healthy.
Fish produce a lot of pollution from defecating and breathing, and if left untreated, this pollution ends up killing fish as they find it difficult to swim and thrive in their waste.
As such, aquarium filters help clear molds and debris, eliminate toxic waste, and aerate the water, thus creating a conducive environment in which fish can grow and thrive.
The specific filter you choose to buy will more likely depend on your budget, experience, and the type of fish you’d like to breed.
In this guide, you’ll learn about the benefits of aquarium filters, the types of filters around, and how you should go about choosing the best aquarium filter for your fish tank.

Benefits Of Aquarium Filters
A Fish-friendly and Healthier Option
There’s no easy way around it. If you don’t invest in a good filter, you’re more likely going to have to clean the inside parts of your fish tank regularly.
This means that you’ll be tasked with constantly removing and placing your fish aside somewhere so that you may give the tank a good scrub.
The frequent shifting and returning of fish back to the aquarium can take a huge toll on fish, making a filter a much friendlier and healthier option.
Low Maintenance
Most fish tanks tend to get dirty rather quickly. If you haven’t yet purchased a filter, you’ll have to clean the fish tank often to keep the water clean and also create a favorable setting in which your fish can thrive.
This frequent cleaning and shifting of fish can be overwhelming and daunting for a person, hence the importance of investing in a good quality filter.
Although a filter may require some occasional maintenance, at least they can significantly improve your aquarium cleaning tasks to a whole new level. Make sure you install one in your system to enjoy its benefits.
Healthier Fish
Filters play an important role in reducing the risk of ammonia stress in fish. This often occurs from high levels of toxins that build up in a fish’s body, especially when waste inside the fish tank hasn’t been cleaned in a while. And as these levels of ammonia stress grow more persistent, this may result in ammonia poisoning and be deadly to fish.
Aesthetic Appeal
Having a filter will dramatically improve the overall appearance of your aquarium a great deal.
The fish tank’s water will also look clearer, and the glass appearance will look much cleaner than you think once you fix a high-quality filter in your aquarium. More importantly, the occasions of unpleasant smells emanating from your fish tank will also become a thing of the past.
Types Of Aquarium Filters
HoB Filter
Also known as Hang-On or Power Filter, the HoB (hang on back) filter is among the most widely used filtration systems among hobbyists to clean small tanks.
These filters work by pulling water in and out through a pump to allow for mechanical, biological and chemical filtration.
Aquarium owners love this filter because it’s easy to maintain, cost-effective, readily available, and requires low maintenance. The only setback associated with this type of filter is that when the media is changed, a great deal of healthy bacteria also gets lost in the process.
Canister Filter
This type of filter is specifically tailored for larger aquariums and is usually fixed underneath the fish tank to provide mechanical, biological, and chemical filtration. These filters are highly efficient and employ more media than other filters.
They are also very quiet, which means you can use them in the workplace or any other setting where silence could be a top priority. Unfortunately, canister filters are quite expensive, difficult to install, and require higher maintenance than most filters.
Sponge Filter
Also known as Air-Powered filters, sponge filters are the most basic and cheapest type of filters around. They comprise a sponge-like material that’s fully submerged in water.
The filter works by pumping water through the sponge using either a water pump or air stone to allow for a very smooth and effective mechanical and biological filtration. Nevertheless, sponge filters are readily available in many different shapes and sizes and are long-lasting, hence a great value for money.
Undergravel Filter
This filter is tailor-made for larger fish tanks and is usually fixed underneath a layer of gravel. It works by pushing water through the gravel to allow for effective mechanical and biological filtration where healthy bacteria can thrive.
Although these types of filters require regular cleaning, their maintenance is rather straightforward compared to other setups.
Some wastes that appear to collect on the substrate surface usually come off easily after siphoning. Undergravel filters are also easy to maintain, cost-effective, and usually provide sufficient growth of nitrifying bacteria.
Finally, because a person shouldn’t over-filter, it’s important that you choose a bigger filter for better performance. Although filters that are specially designed for large fish tanks may appear rather expensive, at least many allow for optimum health care of fish.
On the other hand, if you have a small fish tank, an internal power filter that’s specifically tailored for small aquariums would work great for your fish too.
How To Choose The Best Aquarium Filter
Choosing the best aquarium filter for your fish tank might be a bit overwhelming. There are so many options in the market to choose from. Even though each aquarium filter type works well, they have different roles that can make or break the ecosystem in your fish tank.
You might have to consider what your fish tank needs.
Now that you’ve read about the different types of filters, which one is perfect for your aquarium? Which one should you buy? Here are some steps you should do when choosing your filter:
Choose a filter based on your tank’s size
The amount of water in your aquarium has a huge effect on your choice when buying a filter. The general rule is that all the water contained in your tank can pass through the filter at least four times an hour.
For instance, if your tank contains 20 gallons, your filter should be capable of making the 80 gallons of water flow per hour.
Some suggestions to keep in mind:
- Canister filters best function in tanks that can hold 30 gallons of water or more. These filters are usually large which is good for bigger aquariums. With these filters, you can get a flow rate of 120+ gallons of water per hour.
- Power filters are also known as HOB or Hang-on-Back filters. They are especially recommended for tanks that can hold less than 30 gallons of water. This filtration is gentle and can suck water into the filter without hurting the fish.
Consider the type of fish you’re keeping
The best aquarium filter depends on the kinds of fish types you intend to keep (i.e. whether it’s a pure saltwater or pure freshwater tank).
Saltwater aquarium hobbyists prefer wet/dry filters. For freshwater tanks, you may use canister filters as well as wet/dry filters. If you have reef aquariums, you may need a combination of mechanical filters and protein skimmers.
If you’re planning to breed other fish, sponge filters are the most suitable for your tank. This type of filtration is gentle because it has no moving parts so it ensures the safety of newly-hatched fish.
Consider your budget
Some filters might be costly. Undergravel filters are one of the least expensive filters and can work just as well. The only disadvantage is that it might not be aesthetically pleasing. These types of filters use big pipes so they may seem ugly to the eyes.
Always remember that your fish and tank’s requirements should be met. Some filters might look good and small while others might look too bulky or ugly. However, don’t be fooled by their appearance and focus on what they can do for your fish tank.
Knowing the right filter that works for you can keep your pets alive and healthy. After keeping these steps in mind, you can narrow down the right filter that you want to buy.
