As a passionate fish owner, you know that keeping your aquarium clean and healthy is of utmost importance. That's where an external aquarium filter comes in handy! These powerful machines can handle a variety of filtration media and canister styles to provide crystal clear water for your fish to thrive in. With so many options on the market, it can be overwhelming to choose the right one for your aquarium. That's why we've compiled a list of 10 top-rated external aquarium filters, including the SunSun HW302, to help you make an informed decision that will benefit your fish and aquatic plants.
When looking for an external aquarium filter, there are several important factors to consider. Firstly, the GPH (gallons per hour) of the filter should be compatible with the size of your aquarium. The SunSun HW302 boasts a maximum flow rate of 525GPH, making it suitable for tanks up to 200 gallons, but there are also options available for smaller tanks. Additionally, the number of media trays available and the types of filtration media that can be used are important considerations as they can impact the effectiveness of the filter. The SunSun HW302 comes with 4 media trays, giving you the opportunity to create a custom filtration system with the media of your choice.
Another helpful feature of the SunSun HW302 and other external aquarium filters is the adjustable spray bar. This makes it easy to direct the flow of water where it's needed most, whether that's towards the surface to increase oxygen levels or towards the bottom of the tank to clean up debris. Additionally, the self-priming pump eliminates the need for manual siphoning and the built-in 9 watt light helps control algae spores and promote clear water.
Overall, an external aquarium filter like the SunSun HW302 can be a valuable investment for anyone looking to maintain a thriving and healthy aquarium. By considering the GPH, filtration media options, and additional features like the adjustable spray bar and self-priming pump, you can find the right filter to suit your needs and keep your fish happy and healthy.

As a history major with a background in science, I look at the history of external aquarium filters as a fascinating blend of technological advancements and the passion for preserving aquatic life. These filters have come a long way since the first external filters were developed over a century ago.
The first external aquarium filters were simple sponge filters that required manual cleaning. These filters were not very efficient and required aquarium owners to clean the sponges regularly to keep the water clear. However, this was a significant improvement from the earlier methods that involved changing the water almost daily to keep the aquarium clean.
In the 1960s, the development of bio-filtration revolutionized the aquarium hobby. This is when the concept of using beneficial bacteria to break down waste products was introduced. External filters were now equipped with biological media that facilitated the growth of these beneficial bacteria. The media was usually made of porous materials like ceramic balls, sintered glass, or plastic bio-balls. This development led to the creation of highly efficient filters that required less maintenance.
In the 1980s, the addition of chemical filtration cartridges to external filters became popular. These cartridges contained materials like activated carbon, ion-exchange resins, or phosphate removers to remove impurities like dissolved organics, heavy metals, and harmful chemicals.
The 1990s saw the introduction of canister filters that took external filtration to another level. These canister filters had multiple compartments with different filtration media, making them highly efficient in removing all types of impurities from the water. With the introduction of these canister filters, aquarium owners could now keep larger tanks with a higher stocking density without compromising the water quality.
Today, external aquarium filters are highly advanced and sophisticated systems that employ multiple filtration methods to ensure crystal clear water in the aquarium. These filters come with features like self-priming pumps, adjustable spray bars, and media baskets that allow for customization of the filtration process.
In conclusion, the history of external aquarium filters is a testament to the ingenuity and passion of the aquarium hobbyists. From the simple sponge filters to the highly advanced canister filters, these filtration systems have made it possible for aquarium owners to maintain a healthy and vibrant aquatic environment. Today, external aquarium filters are an essential aspect of the hobby, and they continue to evolve to meet the needs of the ever-growing aquarium community.
The product described above, a 4-tray media filter with a built-in 9-watt UV light and a self-priming pump, offers several design choices that affect the user beyond what the manufacturer says.
First, the four media trays allow for customization of the type of filtration media used, meaning the user can tailor the filter to their specific needs. This is a key feature for users who have different types of aquatic creatures with differing filtration requirements, allowing them to easily swap out the media as needed.
Second, the adjustable spray bar is a helpful feature for users who want more control over the output flow from the filter. They can adjust the output flow to suit their specific tank environment, preventing unnecessary turbulence or stagnation.
Third, the self-priming pump eliminates the need for manual siphoning, making routine maintenance much easier for the user. This is a key design choice that simplifies the user's interaction with the filter, reducing the likelihood of user errors and ensuring that the filter remains in good working order.
Finally, the built-in UV light offers another layer of filtration, controlling algae spores and bacteria and promoting clear water. This is a key choice that adds value for users with a need for advanced water filtration, such as those with sensitive or delicate aquatic species.
Overall, these design choices make the product highly customizable, user-friendly, and effective at promoting clear and healthy aquatic environments.
FAQ About external aquarium filters
Q: Are external fish tank filters better?
A: External fish tank filters have their advantages over other types of filtration such as internal or hang-on-back filters. They provide more space for filtration media which leads to better water quality, they create less noise and vibration, and they are usually more durable than other filters. However, the choice of filter depends on the size of the tank, the type of fish and the volume of waste they produce, and the owner's preference.
Q: What size external filter do I need for my fish tank?
A: Your tank's size determines what size of the filter you need. A general rule of thumb is to have a filter with a flow rate of at least 5 times the volume of your tank per hour. For example, a 50-gallon tank would require a filter with a flow rate of at least 250 gallons per hour. It is important to note that different fish species may have different filtration requirements, and over-filtering a tank can increase current and stress levels in some fish.
Q: Can you have too many filters in an aquarium?
A: It is possible to have too much filtration in an aquarium. An excess of filtration can cause strong currents or water flow, which may stress some fish species. It is also worth noting that over-filtering can remove too many essential nutrients from the water needed for plant growth, and can also increase the rate of evaporation. It is important to strike a balance between maintenance requirements and the needs of the tank's inhabitants.
Q: What size filter cartridge do you need for a 10 gallon tank?
A: The size of the filter cartridge or media required for a 10-gallon tank depends on the type of filter you have. Each filter has its own requirements for the filter media. Some filters require a specific size cartridge while others may require a specific volume of filter media. It is important to check the manufacturer's instructions for the filter you have to know the right size for your 10-gallon tank. In general, a 10-gallon tank would require a small-sized filter cartridge or a small portion of filter media.
