So, you are choosing the best canister filter? The most important fact you should know is that their manufacturers quite often play hanky-panky with you when indicating the amount of water being pumped by a filter per hour.
So, in this respect you should buy a bit oversized filter. And this is it, now you may skip the rest of the article since below there are only boring details and comparisons, characteristics and IMHO as for studied canister filters.
However, if you are interested you are welcome to continue reading…
In general, I’ve listed all worthy filter models and if there are others, then they are made by some noname brands, or they are some rare models, to describe which I haven’t found sufficient amount of information.

Best Canister Filters in 2018
Fluval Fx6 and Fluval Fx4: best canister filter
The company has its best-in-class filter, a powerful filter FX-6 for tanks up to 400 gallons (filter output 563 GPH, 41 Watt).
This filter is made for tanks with large amounts of organics that has to be removed mechanically. These are large tanks with plants or with large fish. Fluval FX 6 also offers a “Smart Pump” technology which ensures the filter maximum output.
The filter has an electronic circuit that continuously controls its operation. Impeller spin speed and rolling force are measured continuously to ensure the filter output and efficiency.
The circuit also provides the filter autorun and removes the air which can accumulate inside the system. Once in 12 hours the pump stops and lets the accumulated air out of the system ensuring by this the best filtration efficiency at any moment of time.
A new smart-pump has been designed for Fluval FX4, which provides the filter maximum output. The pump has a special electric circuit inside which completely controls its operation.
It controls the pump power and rotor speed thus it ensures filter maximum output and power consumption efficiency.
All filtering details were thoughtfully chosen. The filter consists of 4 containers with total filtration volume (14L or 3/7 US Gal) and biological volume 3.9 L (1 US Gal).
Filter baskets come in order in such a way that it provides maximum efficiency and crystal clear water in a tank. Filtering medium and fillers are put in several layers so the water when coming through the filter gets maximally clean from dirt, garbage and harmful microorganisms.
The baskets with fillers have subsidiary filtering sponge on the edges which performs additional mechanical water purification. Each basket is responsible for efficient water filtration; foam performs mechanical, preliminary water purification by capturing the smallest garbage particles.
Fluval FX4 filter has a special handler by means of which you can take out and separate all baskets easy and fast.
Such an improvement was designed to simplify maximally the filter maintenance. Now you don’t have to waste time disassembling the filter completely to wash the fillers.
There is an indicator on top of the filter which helps you to remember the date of the last maintenance.
- Multi-Stage Filter that produces healthy aquarium water, freshwater or marine aquariums
- Features Smart Pump Technology for optimal filter performance, efficiency and management

EHEIM Classic canister filters - 20 years on the market
These filters can be used in any tank, they are plain and sustainable. If you don’t want to get into details and just to buy a filter and turn it on, this is the one you need.
Its drawbacks are that it comes short of filtration rate and some other abilities when comparing to more modern models and you’ll have to buy filtration media for it.
Multi-function models: Eheim 2217 (US gal/h: 264 gph; power consumption 20w) and Eheim 2215 (US gal/h: 164; power consumption W: 15). Despite the fact that «Classic» filters product line has been on the market since 80s it has filters justly called a “willing horse”, some of them have been used for almost 20 years.
One may say that these were classic filter models - Eheim 2215 and Eheim 2217 that made Eheim its good name. EHEIM Classic, sold at Amazon.com, is equipped with filter media (EHEIM Mech & Substrat Pro).
Here is the filter with the simplest design.
It can be considered as a straight pipe filled with filter media.
Filter media in this filter type can be placed both directly in its canister and is a special cassette made for it. When installing the cassette you should push it down harsh but slightly till it is fixed in its lowermost position.
This ensures reliable pressurization between the cassette and the filter case; it excludes ingress of not filtered water back to the tank as well.
- Permo-elastic silicon sealing ring fixed on the pump head for easy and safe closing after cleaning
- Equipped with filter sponges and/or loose filter media
- Accessories included: spray bar, inlet pipe, hose and installation accessories

EHEIM Professional 3 canister filters
They are one of the most modern canister filters, they will do for those who prefer maximum quality and comfort. There is some confusion among the filter models, but I’ll explain.
By means of USB cable the filter is connected to computer and it’s getting easier to control it, though the USB cable you should buy yourself.
In «Professionel 3» and «Professionel 3 electronic» external filters product line the most popular are EHEIM 3e 2076 (up to 105 US Gallons, 435 gph, 35 watts)
Eheim 2075(up to 160 Gal; 330 GPH; 16 watts), Eheim 2073 (up to 90 gal, 276 GPH; 16 Watts) and Eheim 2078 (up to 185 US Gallons, 35 16 watts).
All of them have the shape of elongated cube with a canister divided into sections, filter head with a pump and water preliminary treatment filter in it.
For those who decided to really spend money on the filter I’d recommend to take a look at Eheim 6666 Pro 4+ Canister Filter, the latest model that has just appeared on the market.
There are 3 models you can purchase, the 250, 350, and 600. The 250 is for 30 - 65 galllons, the 350 is for 50 - 95 gallons, and the 600 is for 65 - 160 gallons.
It has Xtender function in it, due to which you can clean the filter more seldom. If the filtering media gets clogged with dirt the flow is redirected and biological filtration efficiency is preserved.
Filter models 250 and 350 can also have an integrated heater as thermo filter (T), at that the company has taken into account aquarists’ feedback and now the heater works separately from the filter.
The most upgraded filter model is 350e, it has the ability to control it by means of computer.

Flexzion canister filter: a best budget choice
Flexzion company (Sunsun China) produces one of the simplest and cheapest filters among all of the presented models.
The company has rather wide product line, but all filters have common characteristics and list of equipment. These filters are in great demand, since quite often price plays a crucial part. But are they really as cheap as they seem? Let’s find out.
For example, let’s consider SunSun Hw304B 525GPH Pro Canister Filter Kit with embedded UV-sterilizer for tanks up to 100 gallons and pump output 370gph.
UV-sterilizer power capacity is 9 W and it provides crystal clear tank water preventing appearance of green algae, different microorganisms and pathogenic bacteria in a tank.
So, you can turn of your UV lamp. The filter has high quality ceramic axel to ensure its noiseless operation.
There are 4 baskets for different filter media – biological, mechanical and chemical one.
The filter is equipped with:
- 9 watt UV
- 3 Pack of EXTRA White Filter Pads
- 1 Pack of Blue Coarse Pad
- 1lb. of Premium Filter Carbon
- 1lb of Ceramic Rings
- 40 Pieces of Bio Balls
Sounds good, isn’t it?
UV plus expendables....
However, in fact all of them are of rather low quality and their amount isn’t enough for the filter to function efficiently. Some models are sold even without all of the stuff mentioned above, they only have sponges.
- Canister filters for aquariums use high water pressure, from a properly powered pump, to force water through the dense filter media. A pump can draw water from an under-gravel filter, and run it into a canister for double filtration
- 3 media trays capable of handling your choice of filtration media; Comes with an adjustable spray bar. This is a helpful feature if you want to adjust the output flow from the filter
- Built in 9 Watt UV sterilizer to help kill algae spores and bacteria, promoting crystal clear water
- Convenient self-priming pump that eliminates the need for manual siphoning; Single valve disconnect & priming pump ease routine maintenance
- Provides quiet, efficient filtration for fresh and saltwater aquariums is great for living rooms, offices or bedrooms
- The filter has UV sterilizer, though it’s not powerful enough to operate efficiently
- The sterilizer comes first and all tank dirt will be accumulated on it, since it has to be placed after filtration
- Rather low price (there are no analogous filters with the same parameters and the same price)
- Very noiseless in operation
- It has a pump for priming
- Rather fragile stop valve (when you turn off the water it seems that it is about to break in your arm)
- Clamps aren’t reliable
- No spare parts
- White color is very easily soiled
- It’s necessary to buy expendables

- Short hoses
Finnex PX-360 Compact Canister Aquarium Filter: best for small tanks
Finnex PX-360 Compact Canister Aquarium Filter is for 5 to 20 gallon aquariums, its output is 90GPH, power consumption 11.5w.
It can be recommended for nano tanks, since its low price allows using it in small capacity tanks and its output isn’t enough to create a strong flow.
However, you have to keep in mind that 20 gallon tank is too large for such a filter, so better use it in smaller ones and for large tanks a more powerful canister filter should be bought.
The Finnex fiter is suitable for 5-10G tanks and if a tank is larger the filter may fail and you’ll have to wash it every week. There are two baskets in the filter: with ceramic media and a sponge and a filter pad.
- Filtration media includes activated carbon floss pad, sponge and ceramic rings
- Perfect for both Aquatic and Turtle Aquariums up to 25 gallons
- Completed accessories include durable water intake strainer, spray bar and filter hanger
- Video: http: //www.youtube.com/watch?v=dKF-CzLFuKk
- 2' Lift available
- Very quiet
- The price
- Super easy to clean
- Doesn’t create a strong flow (90GPH)
- It is supplied with a spray bar
- You can adjust outflow
- Optional sponge on the intake
- Large internal volume
- Super easy to maintain and prime
- Lots of pieces to customize
- Short hoses
- Low power for efficient biological filtration
- It’s advisable to replace ceramic parts with more efficient materials
- Too bulky
- Needs washing too often
- Instruction for assembly is horrible. Make sure you double check with minor leak after you first assemble. Any tiny leak indicates using the wrong parts.
- With active carbon/sponge, flow rate slows down after one month of use in heavily planted tank.
- The baskets are made of very fragile plastic, you should be careful with them
- It has no priming button, so you have to fill the filter with water manually for the first priming
Rena Filstar Canister Power Filter: the mystery
Until recently these filters were produced by another company and they were quite good. Now it has been bought by API and the production has been transferred to China.
How did it influence the filters? Let’s see.
The company has a product line API FilStar XP. Here after XP the model is indicated according to its output. For example, XP 4 filter. One of the most popular models in this line is Rena filstar XP-L (former Rena filstar XP 3).
This is an external canister filter for tanks up to 175 US Gal, output 350 US GPH, power consumption 19 watts. Unfortunately, this model has got negative reviews at Amazon.com.
First of all the buyers complain about low quality of plastic and leakages.
Two years warranty is good, but if you use the warranty coverage several times it’s annoying.
IMHO I’d be very careful when choosing this filter and I’d rather wait for the company’s response to the complaints.
Possibly it’s connected with the fact that after the company was sold the facilities and production have been transferred to China with the expected results.
- Contains one (1) API FILSTAR XP FILTER SIZE L Aquarium Canister Filter 1-Count Box
- Provides very powerful filtration for crystal clear water and healthy environment.
- Designed with self-priming & quick disconnect features to allow safe and easy stop & start of the filtration when maintenance is needed, anti-airlock system to prevent unexpected filtration stops, and anti-noise feature to prevent vibration against cabinet/floor.

- 2 years warranty
- Very quiet
- Large internal volume
- Good quality filter media
- Easy priming
- No extra charges for the brand
- It has no spray bar
- More frequent complaints about leakages
- Low popularity at amazon.com

Cobalt Aquatics EXT aquarium canister filter: the most unusual technical solution
The filter is good for those who don’t have the ability to put a filter under a tank.
This filter’s feature is that it doesn’t need priming and it can be put below, next to and even above the tank! Since it just doesn’t have a pump in its head, the pump is put into the tank together with the intake pipe.
This allows switching of the filter and washing it without turning the pump off. I.e. you turn the latch handle, take away the canister and the pump continues working.
Max flow rate is 210 gph (800l), the filter is for tanks up to 55 gallons, total canister volume is 1.85 gals.
Complete with four pre-loaded media chambers
- 1st stage sponge filter
- 2nd stage activated carbon
- 3rd stage ceramic rings
- Final 4th stage finishing floss
- 5/8" ID hose with plastic snap clamps
- No priming; does not need gravity. Can sit below, beside or above your tank.
- Ideal companion to the Cobalt Micro UV
- 3 year warranty
- Unusual, even unique technical decision
- Very low price
- Ability to maintain the filter without switching it of
- No need in priming
- Canister itself is very sturdy
- Location of the pump outside the canister allows increasing its effective volume
- Three years warranty
- Quick disconnection of valves which allows the water to keep flowing
- Tons of included media
- The filter box is designed to have little or no bypass.
- There is only one filter model in the product line – just for tanks up to 55 gallons
- The pump on the intake pipe consumes additional space in a tank and it’s far more noticeable than a common pipe
- Cheap accessories
- External pump adds more complexity to the setup
- The included plumbing kit is unusable
- No spray bar. This type of filter system generally works better with spray bar to help break surface tension and provide the water with oxygen exchange. Without something in an aquarium to provide this function the fish will suffocate and die.
- The intake screen doesn't fit any of the tubing adapters and will barely stay connected to the pump. For internal pump configurations the screen needs something to affix it to the pump. For external pump configurations you are pretty much screwed.
- Polishing floss is just an unruly mass of loose fluff
- No clamps for hoses either at the canister or at the u-tubes
- No way to secure the intake and outflow hoses from sliding around
Zoo Med 511 Turtle Clean: best canister filter for turtle tanks
Have you ever had a turtle in a tank?
Lucky you are! These creatures eat and…well you understand.
Water in a tank starts to smell just in two days and washing this tank is rather doubtful pleasure.
Zoo Med 511 canister filter was made especially for tanks with turtles – it is supplied with a spray bar for better water aeration. Besides turtles like lying in water flows that come out of the spray bar.
The filter is made for tanks up to 60 gallons. But this is a manufacturer’s trick – in fact the filter will only do for a tank up to 30 gallons.
It’s not powerful enough for 60 gallons thus I’d recommend to use Api Filstar or Cascade 1000 filter in this case. They are a bit more expensive, but they have better characteristics.
- Provides greater aeration with the included spraybar
- Removable hose-connecting device
- Adjustable flow control system
- External canister filter for turtle habitats up to 75 gallons (284 liters) in size
- 265 gallon per hour (gph) rating
- Slim line design fits in tight spaces
- Double filtering system with internal biological recirculation
- Easy priming feature, Combines mechanical, biological, and chemical filtration. Included spray bar to increase oxygenation.
- Low price
- The filter is extremely easy to disassemble and clean and its fairly user friendly
- Good technical support
- In fact the filter is for tanks up to 30 gallons, but not for the stated 60 gallons
- Fragile plastic used. If you choose to purchase this, use extreme care when manipulating the poorly manufactured caps.
- Frequently breaks
How To Pick A Best Canister Filter
How to find best canister filter?
I assume you’re quite busy guys and you don’t have time to read all of this and enter into all the details.
Well, me either.
There is a rather wide range of external filter brands and there are much more filter models on the market.
What is confusing that famous and old brands have a lot of different filter models – easy in care and cheap ones, expensive and sophisticated ones.
If you want to buy a filter for your tank and you see one or three models provided by the brand, it means that the company isn’t focused on filter production or maybe it has just entered the marked.
In my opinion company’s specialization is important since it is a determinative factor and those who produce lots of stuff in small amounts loose to those who are focused on production of just one product.
The rest of filters: it’s difficult to tell
There are some external filters which aren’t very popular so it’s rather difficult to give any feedback. First of all because they are produced in China and even their manuals are written in Chinese.
So what is it exactly – biological, mechanical and chemical filtration?
• Biological filtration, i.e byproducts transformation in a tank. This involves deactivation of ammonia and ammonium which are toxic for tank inhabitants and transferring them into less harmful nitrates that in turn are partially recycled by tank plants and partially removed when performing water renews.
Biofiltration is performed by nitrifying bacteria that inhabit in a filter.
Technically speaking any filter is more or less occupied by nitrifying bacteria and it can be called a biological one. The thing is that biofiltration is just more efficient in filters of larger volume than in smaller ones.
• Mechanical filtration or cleaning the water of organic or inorganic suspended matter.
Many people consider that this is the main purpose of any filter. Of course it’s not very nice to see muddy tank water.
However, the main operating result of a filter is still an efficient biofiltration, not just cleaning tank water of suspended matter and mud. In case of well arranged biofiltration process the tank water is crystal clear.
• Chemical filtration is based on filter medium and tank water interaction that changes the water properties or content of some matters in the water.
Ionite, zeolite and other substances are used as a filter medium.
• Adsorbtion of some substances (for example some medicines after the treatment was finished) this is when carbon is used.
The larger is a ratio of filter media to a tank volume the more efficient filtration is. It’s rather difficult to put a large filter in a tank, since it’ll take additional effective volume.
Such internal filters are the best for small or sparsely populated tanks. In the rest of cases an external filter should be chosen.
