What is a canister filter for aquarium?

This is a device that forces aquarium water through the siphon tube, filter media, and back to the tank via a pipe, which makes it perfect for removing small particles, old fish food, waste products, feces, and dirt. With a correctly chosen canister filter aquarium requires cleaning less often, and water stays transparent and fresh for longer. Since different filter media can be installed in a filter, it’s highly adaptable to different conditions and can be customized according to the capacity of the aquarium, kinds of fish, and so on.

What makes this type of filters pretty popular is the fact that they can be used for large aquariums (40 gallons and larger), and perform chemical, biological and mechanical cleaning. This kind of filters is good for saltwater, aquariums with live plants and cichlid. The only drawback of canister filters is that there’s no air contacting water during cleaning, so biological filtration and oxidation isn’t good enough for them.

The Three Stages Of Aquarium Filtration

Mechanical Filtration

With the help of coarse sponges, floss, and ceramic noodles, large impurities are removed, and the water is polished.

Chemical Filter Media

As a rule, the carbon material is used for chemical filtration. Such impurities as tannins, odors, and medicines are absorbed in the material. Some chemical filters absorb copper, nitrates, and phosphate, while a water softening pillow serves to optimize General Hardness of water.

Biological Filtration

Biological filtration is a must for preventing bacteria colonies growth within the filter. Most filter models use bio-wheels, bio-balls, and ceramic noodles.

Benefits of Using a Canister Filter

High Flow Rates

To make sure that aquarium inhabitants stay healthy, you need to keep water clean all the time. Changing water manually every 1-2 days is too inconvenient and time-consuming. Automatic canister filters clean water efficiently and quickly – it should be changed only once a week.

Flexible Media Selection

Most types of canister filters allow users to select different types of media and arrange it in the order they want. Some enthusiasts are okay with 2-step filtration, while others organize 5-step filtration – it depends on the capacity of the filter.

Easy Setup Processes

Canister filters are quite easy to assemble and install, and most models require priming only once to start working. Detailed instructions make the setup process simple even for newbies.

Easy to Clean

Since aquarium canister filters are easy to re-assemble, they can be cleaned quickly. No special cleaning agents are required, and the media can be replaced.

Quiet Operation

Some canister filters work without making any noise so they disturb neither your family nor the fish.

Strong Mechanical Filtration

Changing water is not as efficient as a professional canister filter – thanks to high-quality media and electric motor, it makes water crystal clear removing even minor impurities.

 

Aspects To Consider When You Make A Purchase

Tank Size vs. GPH

The aquarium volume and filter capacity (usually measured in gallons per hour) should be considered primarily. Select a suitable canister filter that is able to clean the entire aquarium at least 2-3 times during an hour. If you choose too small and non-efficient filter, the aquarium water will get dirty soon. On the contrary, large canister filters won’t fit small tanks properly.

The Motor

Since the motor will work around the clock, you need it to be robust, long-lasting, and yet not energy-consuming. The most optimal choice is a motor with UL approval rating. You can either buy an epoxy-sealed motor that is protected against moisture or a magnet-driven motor that has a self-priming feature (it’s not sealed, so its performance can be impacted).

The Valves

Canister filters are equipped with 2 valves: one controls the intake and another – the output. The valves should be closed totally to prevent leaking. Ideally, you should be able to disconnect the valve hoses to set up an adapter or a gravel vacuum.

Filtration Process & Media Trays

Select the filter that features a media tray for every filtering media. Using all three filtering stages, you’ll reach the best results.

Location

Check out the canister dimensions to make sure it will fit in the tank.

Interesting facts

An aquarium without filtering

  1. Carbon media is effective in removing toxins along with small impurities and dirt particles.
  2. The golden rule of choosing an aquarium (and the filter accordingly) is “One fish per gallon for the tank”.
  3. The replaceable filter should be replaced once a month depending on the volume of the aquarium, a number of fish and media used.
  4. It takes about six weeks to set up an optimal environment in a new fish tank. As soon as it’s done, maintaining it gets easy.
  5. If you don’t maintain a normal level of nitrates, they can cause problems with algae that cannot be eliminated by filtering and cleaning.

Penn Plax Cascade aquarium filter

Penn Plax Cascade Canister Aquarium Filter

Review

Penn Plax Cascade canister aquarium filter is designed for aquariums with a capacity of up to 100 gallons. It performs all three kinds of filtration (chemical, biological, mechanical) and is allowed to be used in marine and freshwater tanks. Media consists of several layers: the floss pad cleans fine particles, and the activated carbon absorbs toxins and dirt from water. The coarse sponge layer ensures sufficient biological filtration by boosting the growth of bacteria and removing waste, fish food and ammonia from water, as well as nitrates. The tubing connectors can be used to adjust the device’s flow speed. Besides, this canister filter for 100 gallon aquarium features 4 locking clamps and a motorhead with in-built O-ring ensure a tight fit.

Our opinion

A versatile and non-expensive solution, but it is prone to failures.

PROS

  • provides all three types of filtration;
  • easy to install;
  • suitable for large fish tanks;
  • allows for using any combination of media.

CONS

  • it’s pretty loud;
  • breaks pretty quickly and often should be replaced under warranty.

Fluval Aquarium Canister Filter

Review

If you’re searching for a very efficient solution, pay attention to the best aquarium canister filter from Fluval: it features a high flow rate (more than 350 gallons per hour) and has a special design that allows keeping up to 50% more water than models of the same size. The contact with the filtration media is maximized. Several filtration baskets are already equipped with all the necessary media. Thanks to 1-motion lock clamps, installation is a one-minute affair. The kit also includes an intake strainer, 2-layer foam screen, lift-lock clamps, and the instant prime system.

Our opinion

A great filter for its money, suitable for any type of water, but prepare to maintain it properly.

PROS

  • works with fresh and saltwater aquariums;
  • has three filtering stages;
  • a very high flow rate.

CONS

  • leaks at the corners of lift-locks;
  • the O-ring has to be replaced often.
Marineland Canister Filter

Review

Marineland aquarium canister filter performs all stages of cleaning taking filtration to the next level. The model has a black diamond carbon filter that removes odors and water impurities, biological filter balls that ensure biological filtration, and the polishing filter that gets rid of the finest dirt particles. The self-priming function is present, as well.

Our opinion

This filter works with both marine and freshwater aquariums up to 100 gallons. If you’re ready to pay twice as much as for a usual filter, this model would be agreeable.

PROS

  • performs all three types of filtering;
  • a democratic price.

CONS

  • the outlet tube is pretty weak;
  • doesn’t have UV light for killing bacteria;
  • metal hose clamps for fixation aren’t included;

Pingkay aquarium canister filter

Pingkay 200 Gallon Filter Aquarium Tank Fish Canister

Review

Those who own big fish tanks should opt for LKF’s canister filter 200 gallon aquarium that comes with literally everything required for installation: input and output tubes, curvy bars, UV light bulbs, bio-balls, input covers, spray bars, and a lot of other stuff. The device performs 5 stages of filtration and may be used for aquariums with fish and turtles. UV light eliminates viruses and parasites, while the prefilter on the top removes coarse dirt to prolong the lifetime of all other filters. Water flow can be adjusted with an adapter lever.

Our opinion

PROS

  • suitable for large fish tanks;
  • features UV light for killing bacteria;
  • pretty cheap;
  • the kit features all you need for installation.

CONS

  • pretty loud;

There are two filtering systems: mechanical and biological, as well as automatic oxygen enrichment. The model is compact and features tools and details for installation. Additional accessories include a hose, inlet pipe, spray bar, etc. The silicone sealing ring on the pump prevents leaking and ensures a tight grip after cleaning. Filter media and sponges are included in the kit. According to multiple reviews, EHEIM aquarium canister filter is silent and easy to care about.

Our opinion

This is a non-expensive model that features everything for great filtration except chemical filtering system. Be ready to buy and replace some spare parts.

CONS

Hydor aquarium canister filter

Review

The designers managed to create a perfect ecosystem for water filtering in this relatively small, but efficient device that can be equally useful for fish and turtle tanks with marine and fresh water.

Our opinion

A premium filter with a high efficiency for large aquariums, but it’s quite costly, just like the spare parts for it.

  • performs all stages of cleaning;
  • has a tight sealing, doesn’t leak.

CONS

  • spare parts for replacement are quite expensive;
  • relatively expensive;
  • doesn’t have UV filtering.
SunSun HW-302

SunSun HW-302 3-Stage External Canister Aquarium Filter 264GPH

Review

SunSun aquarium canister filter applies a high water pressure to clean water properly and get rid of the finest dirt particles. The pump forces water via an under-gravel filter for double filtration, and 3 media layers are complemented with an adjustable spray bar for adjusting the flow rate. The self-priming pump eliminates the necessity to fill the filter manually, and a single valve disconnection makes cleaning and installation very simple. It’s the best model for silent filtration of both salt and fresh water.

Our opinion

Silent, compact and non-expensive – most customers love it. Highly recommended for medium-volume aquariums.

PROS

  • a compact mini canister filter aquarium;
  • features all stages of filtering;
  • has a self-priming function.

CONS

  • 1-year warranty (many other manufacturers give a 3-year warranty);
  • starts leaking too soon.
Fluval Canister Filter FX6

Fluval Canister Filter, FX6 Filter (400 Gal)

Review

If you need an extra large aquarium canister filter, opt for the solution from Fluval. This model is suitable for both freshwater and marine tanks, and the Smart Pump technology ensures optimal performance. The filter should be maintained on a monthly basis.

Our opinion

Being the best rated canister aquarium filter, Fluval FX6 filter does what is said on the label: it has all necessary functions. However, it is quite costly, and buying two 300 GPH filters can be more economically beneficial.

PROS

  • Features all stages of filtering;
  • Has a multi-direction nozzle;
  • Notifies user about monthly maintenance.

CONS

  • Very expensive;
  • Takes up pretty much space.
API FILSTAR XP Aquarium Canister Filter

API FILSTAR XP Aquarium Canister Filter

Review

If you have a small tank, API Filstar of S size will fit it perfectly. It provides efficient filtration of fresh and salt aquarium water and maintaining is a no-brainer. The centralized control panel allows for managing all filtration functions. It’s disconnected quickly, prevents leaking, has a self-priming function, and is cleaned easily. You can put several types of media inside in any order.

Our opinion

Although this filter can be great for small tanks thanks to its compact size, it’s not worth the cost which is higher than the average. If you can afford to buy a larger filter, consider this option. Users complain that this model isn’t long-lasting.

PROS

  • Compact and small;
  • Has 3 stages of filtration;
  • Easy to assemble and clean.

CONS

  • According to user reviews, it breaks up quickly and sometimes the delivered product is already damaged.
Aquatop CF500UV 5-Stage Canister Filter

Aquatop CF Series Canister Filter (370 and 525 GPH with UV)

Review

The model from Aquatop is a real find for caring fish keepers: it has a 4-stage filtration system plus UV light to kill bacteria. Although it’s said to be suitable for tanks up to 175 gallons, it has a very high efficiency rate of 525 gph. To top it off, the model is very quiet and compact – it will fit in small tanks ideally. According to aquarium canister filter reviews, this variant is reliable and long-lasting.

Our opinion

We love everything about this model except for its price. Aquatop CF cost is twice as high as the average.

PROS

  • UV sterilizer for extra clarity;
  • Very high efficiency;
  • Allows for 4-stage filtering.

CONS

  • Allows for 4-stage filtering.

Cascade CCF4UL Canister Filter For Large Aquariums and Fish Tanks – Up To 150 Gallons, Filters 315 GPH

Review

The Cascade series of Penn Plax aquarium filters are widely known for their excellent functionality, top-grade quality of filtration, and reliability. The Cascade 1200 is no exception. It is powerful enough to handle up to 120 gallons of water and comes with a variety of useful features. Capacious compartments for filtering media provide a lot of flexibility. A self-primer and two 360-degree rotating check valves add a lot of convenience.

What we think

If you are looking for a truly high-grade device for a large aquarium, the Cascade 1200 filter is the one to consider. Like all big canister filters, it is not too quiet and a sort of cumbersome. Also, it is pricey, though it is worth it.

PROS

  • the superb quality of water filtering;
  • large containers for media;
  • 360-degree rotating valves;
  • a self-primer feature.

CONS

  • large and noisy;
  • a bit pricey.

Finnex PX-360 Compact Canister Aquarium Filter

Review

This small canister filter comes with a bunch of features. It can be used as both a HOB and a desktop option. The hanger is included, as well as a water intake strainer and a spray bar for the water diffusion. The filter can handle up to 25 gallons of fresh or marine water in all kinds of aquariums.

What we think

All in all, this is a good affordable solution for small fish or turtle tanks. It is a bit quieter than classic canister filters but still powerful enough. On the minus side, it doesn’t have a self-prime feature, which means you have to pump water manually when you use it for the first time. While many accessories are included, the quality of native hoses is average.

PROS

  • quite inexpensive;
  • versatile in terms of its placement;
  • many accessories included;
  • low noise level.

CONS

  • no self-primer;
  • the quality of stock tubing is average.

How to Use Aquarium Canister Filters?

Before starting to use the device, you should figure out how to set up a canister filter for aquarium. As a rule, models come with all necessary spare parts for installation. Make sure that they’re all assembled before placing the filter on its position. Then connect the inflow and outflow pipes to the tank following the instructions. Place it on the spot where no one disturbs the filter.

How to Prime a Filter?

Although some aquarium filters have the self-priming feature, and others come with detailed directions and instructions, you can try one useful trick. When you have assembled the filter, submerge it in the aquarium and plug it in. Tilt the canister on its side to have the impeller submerges and start it up. Hold it like that for one minute and then tilt upwards to get rid of air. Now it should be primed.

How Often to Replace Filter Media?

It depends on a number of factors, including the size of the aquarium, amount of fish, water, and the type of media used. To find out whether the filter should be replaced, check the water with a test kit that evaluates the level of ammonia and nitrates in the water. Make sure that these levels are normal: they should be close or equal to zero. If not, it’s time to change the filters. Don’t forget that the filter itself should be cleaned, as well. Ideally, you should do that at least once in 3 months.

In What Order the Filter Media Should be Placed?

First, make sure that you get the right type of media for the filter. As a rule, layering from back to front looks the following way:

  • ceramic rings;
  • coarse sponge;
  • bio media;
  • wool pad.

Where should the Purigen (chemical filtration layer that removes ammonia, nitrates, and so on) be placed? It’s better to put it where the water exists, so it can be placed before it goes to ceramic rings.

The filter leaks. Why?

It may mean that either the spare parts are damaged, or all joining parts aren’t properly sealed. Re-assemble the filter following all instructions strictly, and check all details for wholeness. All broken and damaged parts should be replaced. Make sure that the system is sealed normally; otherwise, air will get inside and form air bubbles.

Most Frequently Asked Questions About Canister Filters

Q: How Do Aquarium Canister Filters Work?

A:Aquarium canister filters use magnetic motors that activate water flow. The water is pumped through the filter to remove particles and impurities. After that, it goes back to the aquarium, pure and clean.

Q: How Much Energy Does a Canister Filter Need While Running?

If you use a canister filter in a freshwater aquarium with water of room temperature, a canister filter for a small tank (up to 10 gallons) will consume about 150 kWh a year. Medium tank filters (for tanks up to 30 gallons) needs about 150-200kWh a year. Filters for large aquariums need about 400 kWh per year.

Q: How to Get Air Out Of a Canister Filter?

A: Raise the spray bar to release the trapped air – it can be done during any maintenance session. Other canister filters have a valve on the canister top – it should be opened to let the air out.

Q: Can I Use a Canister Filter For a Saltwater Tank?

A: Yes, you can install a canister filter with several filtering stages. However, there’s always the risk that it will spoil faster due to ‘nitrate factory’ effect. Therefore, you’ll need to clean it more often, and use activated carbon for eliminating odor and chemicals.

Q: How to Layer Media in a Canister Filter?

A:For the best efficiency, the media should be laid in the following order:

- Mechanical media (sponge, filter floss);

- Chemical media (Purigen, carbon);

- Biological media (Matrix, bio-balls, etc).

Some users lay Purigen before the water goes in the tank to improve its polishing property. Activated carbon is also recommended to remove odors and nitrogen.

Q: What is the best thing to wash a dog with to kill fleas?

A: Fleas cause a lot of discomfort to dogs. These annoying little creatures bite pups, making them suffer; moreover, they can attack people sometimes. No surprise loving dog parents try to get rid of fleas as soon as possible. The best way to do it is by using special anti-flea shampoos. They contain special active ingredients that kill both fleas and their eggs and prevent their further distribution. Additionally, you may use some natural products, though their efficiency is lower.

Q: What kills fleas on dogs naturally?

A: If you want to combine the use of a flea shampoo for dogs with natural products, there are several useful remedies you can try. A spray of apple cider vinegar with salt balances the pH level in a dog naturally. It creates an environment optimal for the animal yet unbearable for fleas. Create a solution of water (four cups), apple cider vinegar (six cups), and a dash of sea salt. Spray the solution right onto your pet's coat. Another variant is to queeze enough lemons to fill half a cup, dilute it in two cups of water, add some dog shampoo and wash your dog with the formed solution. It’s also a good idea to place several leaves of fresh Rosemary in boiling water. Strain the mixture, add it into warm water. Let it cool to a comfortable temperature and pour over your pet. Don't rinse him, just let him dry naturally.

Q: How do I choose a canister filter?

A: Canister filters are effective and reliable but it’s crucial to choose the right device for your aquarium. There are several key criteria for you to consider. The main parameter is the GPH (gallons per hour) rate. A good filter must handle all the water in the aquarium twice or thrice for an hour. Thus, for a 10-gallon tank, a 30-GPH filter will do. Other things to consider are types of filtering media, the motor, check valves, and the filter dimensions.

Q: How often should canister filters be cleaned?

A: Depending on the model of your aquarium canister filter, the routine of maintenance may differ. Canister filters do a great job of pulling all the gunk out of the tank. However, all the water passes through it bringing the gunk into it. So, once you notice the filter is filthy, the aquarium water has acquired a bad odor, the water has become cloudy, the level of nitrate in the tank is high, the canister filter is clogged, or the debris inside is already visible, it's time to clean it. On average, canister filters must be cleaned every three months. In fact, these filters go the longest between cleanings.

Our Recommendations

To make sure that your fish and turtles are happy and healthy, you should create the ideal ecosystem in their tank, and the quality of water should be the primary concern. Keeping it free from dirt and rich in oxygen is vital for the inhabitants of aquariums, so you can’t ignore such an important thing as filtering. Canister filters are versatile and efficient because they’re designed for cleaning marine and freshwater and removing the vast majority of dirt and toxins.

You can find a canister filter for an average price of $70. Out of all the reviewed models, Marineland Magniflow has the most optimal price/quality ratio: it’s non-expensive and features an extra polishing media layer. Aquatop CF Series Canister Filter for tanks up to 175 gallons has exceptional features but is twice as expensive as its analogs. Have a huge aquarium? Instead of Fluval Canister Filter FX6, which is too costly (over $300), we recommend using two Pingkay 200 Gallon Filters – it will be cheaper (though much space is required).

Each best aquarium canister filter review on our list will give you the idea of what this or that model is capable of, and whether it would be suitable for your aquarium. You just need to get a canister filter of appropriate flow rate and buy all necessary media – all the rest will be done by the device.

The most dedicated aquarium owners know that good filtration is essential to having a healthy tank, and aren’t likely to skimp on quality for any reason. You’ve probably tried several different brands of top canister filters, and owned a few good canister filters over the years.

Mary Ramos

An aquarium filter is a must when it comes to clearing waste products and other toxins from your fish’s water, as well as supplying the fresh oxygen your scaly friends need for survival. Canister filters are are known for their power, and they’re generally for use with aquariums that have a capacity of at least 40 gallons. They’re made to operate outside the tank, which is most cases is preferable, since they can easily be hidden in the cabinet underneath your aquarium. When choosing the right one for you, make sure it’s designed to handle the capacity of your fish… Read more »

What is the best canister filter for freshwater aquariums?

Alisa Mendoza

Hi,
All the canister filters reviewed do their job well. The main thing to consider is the size – a filter must fit in your water tank. Otherwise, choosing a filter for a freshwater tank is not a problem if you know what parameters you need.
