Guide to Choosing the Freshwater Filter for Aquarium

Here are the top five things you should be concerned about in looking for a filter.

Size

The size of your aquarium should be your first consideration. You don’t want to buy an overpowered or underpowered filter. Most aquarium manufacturers display the filter’s capacity on the sales page.

Power Consumption

Every watt of electricity counts these days as more and more household items require power or charge. You should find a filter that consumes as little energy as possible. Some products on the list below only require the same amount of power as a light bulb.

Budget

There are $50 filters, and there are $150 filters. Both kinds have their merits, and the decision may finally come down to your budget. If it does, it is a good idea to strike a balance between your price and performance. Our list below contains products on both sides of the spectrum.

User Reviews

User reviews can tell you things about a product that you don’t think to check. For example, reviews can tell you that a filter requires a certain level of skill to install. If you’re all-thumbs, you’ll know that’s not the product for you.

Ease of Maintenance

It’s easy to overlook this as you shop for your filter, but it’s critical. You want to get a filter that can be cleaned and handled easily. You also want one with carbon filters that are easy to find and replace.

Top 15 Best Freshwater Aquarium Filter

Now that you know what to look out for, let’s dive right into the products. This list features a variety of products, from submersible to hang-on filters, and from budget-friendly to high-end machines.

Fluval C Power Filter

The Fluval C Power Filter comes in three standard sizes – C2, C3, and C4. The C4 has a capacity of between 40 and 70 gallons and can filter 264 gallons per hour. Arguably, the most impressive thing about this filter is its 5-stage filtration process. It’s common for aquarium filters to feature one or two filtration stages, but five is on a different level!

Each stage handles a different kind of impurity – chemical, biological, and mechanical. Additionally, the filter has activated carbon and poly/foam that make the water purification more efficient. You definitely won’t find these features on most filters, and that’s why the Fluval C Power Filter is the first on the list.

­Seachem | Tidal Power Filters

Here’s a product so powerful you’d think it was underpriced. It has a superb balance of out, energy consumption, and efficiency. With the ability to handle aquariums of up to 110 gallons, it is suitable for most fish-lovers. Besides its great mix of features, it was also manufactured using high-quality materials like durable plastic and Rubbermaid.

This aquarium filter is easy to install and easy to clean. And since it’s perfect for freshwater tanks, you’re going to have no problems at all. The filters need to be changed every month, so you should consider buying replacements along with the product to save money.

Aqua-Tech Power Aquarium Filter

Manufactured by Aqua-Tech, this product has a 3-step filtration. You may think it pales in comparison to the 5-step filtration of the Fluval C Power Filter until you find out how it actually works. Instead of doubling down on each of the steps, Aqua-Tech designed this filter to efficiently clean the water as it passes through the chemical, mechanical, and biological filtration stages.

The Power Aquarium Filter has a maximum capacity of 60 gallons, which is enough for most people’s needs. Even though the filtration rate is unspecified, it’s estimated to be around three times the aquarium capacity or 180 gallons per hour. The product also comes with a 2-year warranty.

Whisper IQ Power Filter for Aquariums

If you’ve ever owned a fish tank, then you can understand the value of quiet filters. Aquariums aren’t noiseless – the fishes make barely audible sounds as they prance around their liquid homes. But add the wrong kind of filter, and the noise can go from inaudible to “make it stop” in no time at all!

With Whisper IQ Power Filter, you don’t have to worry about anything like that because the product is one of the quietest filters on the market. With an operating sound of less than 40dB, it’s impressive that it can handle a 60-gallon tank and filter at the rate of 300 gallons per hour.

Penn Plax Cascade 1000 Canister Filters

This is the first filter with a cascade design on this list. Cascade filters work by passing the water through different levels of filtration. Each cascade is responsible for a different filtration level, and as the water moves, it’s cleaned up and ready to go. The Penn Place Cascade Filter can handle aquariums of up to 100 gallons, and it can filter up to 265 gallons of water every sixty minutes.

The filter also has flexible flow valves that you can adjust to whichever direction you prefer. This function is particularly useful if you have a narrow aquarium cabinet. Unfortunately, like most cascade filters, it needs to be primed before it can begin operation.

MarineLand Magniflow Canister Filter

MarineLand Magniflow Canister Filter is very similar to the Penn Plax Cascade Filter reviewed previously. They work via the same principle and share many of the same features. However, the Magniflow Canister Filter is distinguished in some small but distinct ways.

Firstly, it has an elegant, classy black finish. It is also versatile for being able to handle both freshwater and saltwater aquarium. Finally, it is satisfyingly quiet during operation.

MarineLand Magnum Polishing Internal Canister Filter

The fact that this filter is submersible makes it superior to many other filters in the same category. The canister also features something called a “micron cartridge.” The Micron cartridge makes the filtration process more useful by adding a polishing process.

MarineLand Magnum Polishing Internal Canister Filter is excellent for aquariums of up to 97 gallons. The setup is relatively easy, and you can do it without any assistance. However, if you experience any difficulty, the product comes with an instruction manual. There are also helpful videos online.

Aqueon QuietFlow LED PRO Aquarium Filter

If there was ever a high-tech aquarium filter, this is it. It has everything you could want from an aquarium filter with some extra features. Some of them are incredibly useful, like a self-priming ability, LED Indicator Lights, and whisper-level operational noise. Some others, like its unique design, are simply for aesthetic pleasure.

The LED indicator reminds you to change your filters by monitoring the filtration system’s efficiency. The Aqueon QuietFlow contains 25% more activated carbon than most filters in its category and can handle aquariums of up to 75 gallons.

Fluxal FX4 Canister Filter

Even though this product belongs in the class of canister filters, it’s unlike anything you’ve ever seen before. There are a few reasons for this, but it mostly comes down to the product’s design. From the outside in, it’s structured for one thing only – efficient filtration. The Fluxal FX4 Canister Filter is more expensive than most filters, but once you see its features, you’ll understand why.

Firstly, it is self-starting; you don’t need to prime it in any way. Secondly, the filter automatically releases trapped air every 12 hours to make the filtration process even more efficient. Thirdly, it has a capacity of 250 gallons, purifying a stunning 700 gallons every hour. The filter is pricey but worth every penny.

AquaClear Fish Tank Filter

If you’re shopping for the first time, you may not be familiar with AquaClear. They are one of the most reliable, most affordable manufacturers of aquarium filters featured on Amazon. This particular model has a capacity of 110 gallons, and it comes with a 2-year warranty. AquaClear is so confident in their product that they are willing to give you your money if you don’t like it!

Besides its impressive capacity, the product also features a re-filtration system that gives water a second pass at the filter media. This results in an efficient filtration process that saves power and maximizes the disposable filters’ lifespan.

Tetra Whisper Power Filter for Aquariums

The Power Filter by Tetra can clean aquariums of up to 60 gallons quietly. But the whisper technology isn’t the most alluring thing about the product; it’s the filtration ability. During operation, this product can trap both odors and water colorations using the activated charcoal in its filters.

The Tetra Whisper Power Filter for Aquariums can also catch debris floating in the water. You can also expect clear water and clean aquarium glass while using this product.

Tetra Whisper EX Silent Multi-Stage Power Filter

At this point, the quiet operating sounds of this filter should come as no surprise to you. Tetra is steps ahead of every other aquarium manufacturer in this area. The manufacturer is also adept at producing budget-friendly, effective aquarium filters. This model can handle an aquarium of between 40 and 70 gallons.

Tetra Whisper EX is one of those filters where you can go from unboxing to top-notch water filtration in no time at all. The installation is as easy as mounting the device on the aquarium. It doesn’t need priming, and the filter changes are quick and easy.

Fluval 307 Performance Canister Filter

This is another high-tech filter by Fluval. Like the FX4, it’s also expensive, but it gives you great value for money. The filter was designed to be one of the quietest Fluval filters ever created. According to the manufacturer, it is so energy-efficient that it has the same consumption as a LED bulb.

There are other superior features, like a swift and straightforward priming process, and seamless piece integrations. Some filters require a degree of expertise to install, but the Fluval 307 Performance Canister can be set up by anyone.

Fluval 407 Performance Canister

This is the last in an impressive line of Fluval-manufactured-canisters we’ll be reviewing. This model has nozzles that you can point in whichever direction works best for you. It can also handle a 380-gallon-aquarium, which makes it one of the most powerful filters we’ll be reviewing on this list.

Other features include a multi-stage filtration process, long-lasting and easy-to-change filters, and an energy-efficient design. It also has minimal power consumption.

MarineLand Penguin 350 BIO-Wheel Power Filter

Without bias, we can say that this is a very advanced piece of machinery. The filter features several elements that drive this point home, including a multi-stage filtration process, efficient power consumption, and versatility. By versatility, we mean the filter can accommodate a wide range of MarineLand cartridges.

It also features a rotating BIO-Wheel that adds a whole new dimension to the filtration process. The BIO-Wheel also eliminates the need for many complicated components, like air pumps, valves, and tubing.

Conclusion

Since we’ve shown you how to get the best freshwater aquarium filter, let’s go over some tips for maintaining your tank. First, never empty the tank. Regularly Cleaning your tank and filter is something we recommend, but it requires some finesse. If you empty the tank, you’ll lose some beneficial bacteria that would otherwise maintain the tank’s health. But this also doesn’t mean you should clean the tank sparingly. Even with a great filter in place, your tank will still need a human touch. You should also consider adding some decorations to the aquarium if you don’t have them already. They can provide a more stimulating environment for the fish, as well as make the tank more visually appealing.
