13 best aquarium canister filters

Aquarium canister filters are essential components in maintaining a healthy and clean aquatic environment for fish and other aquatic pets. These filters are popular among aquarium enthusiasts for their efficiency and versatility. Here are some key aspects of aquarium canister filters:

  1. Filtration Process: Canister filters operate through a multi-stage filtration process.They typically incorporate mechanical, chemical, and biological filtration to remove debris, impurities, and harmful substances from the aquarium water.

  2. Mechanical Filtration: The first stage of filtration involves a mechanical filter media that traps and removes solid particles such as uneaten food, fish waste, and plant debris. This prevents these particles from circulating in the water and negatively impacting water quality.

  3. Chemical Filtration: Many canister filters include a chamber for chemical filtration. This may involve activated carbon or other chemical filter media that adsorb and remove dissolved impurities, toxins, and odors from the water.

  4. Biological Filtration: The biological filtration stage provides a habitat for beneficial bacteria that break down ammonia and nitrite, which are toxic substances produced by fish waste. This helps establish a stable nitrogen cycle in the aquarium, essential for the well-being of aquatic life.

  5. High Flow Rate: Canister filters are known for their high flow rates, which means they can circulate and filter a large volume of water efficiently. This is especially important in larger aquariums or those with a high fish population.

  6. External Placement: Unlike some internal filters, canister filters are typically placed outside the aquarium. This external placement not only saves space within the tank but also allows for easy access to the filter media for maintenance.

  7. Versatility: Canister filters are versatile and can be used in both freshwater and marine aquariums. They are suitable for a variety of tank sizes and are often recommended for larger setups.

  8. Quiet Operation: Many canister filters are designed to operate quietly, which is advantageous for maintaining a peaceful environment for both the aquatic pets and their owners.

  9. Customizable Filter Media: Users can customize the filter media in canister filters based on their specific needs. This allows for tailored filtration to address the unique requirements of different aquarium setups.

  10. Regular Maintenance: While canister filters are efficient, they require regular maintenance. This involves cleaning and replacing filter media to ensure optimal performance and water quality.

When selecting a canister filter, it's important to consider factors such as the size of the aquarium, the type of aquatic life present, and the specific filtration needs. Always follow the manufacturer's instructions for installation and maintenance to ensure the longevity and effectiveness of the filter.

User questions & answers

Question: yesterday i cleaned out my filter and i put it back on but it wont suck in water from the pipe there is no pressure even after i pump it. why
Answer: I came home and my filter was not running. I have had this for a month and it was running great. I cleaned out the filter, etc. and cannot get it to prime. I feel like I have tried everything! I filled the canister with water and it will not prime. When using the prime button, the water goes up to a certain point but does not prime.. Help!
Question: What is the difference between the 1000, 1200, and
Answer: What the others said. Personally I would get the largest you can afford. More filtration is never a bad thing. The 1200 and 1500 use the same filter pads.
Question: Will filter work for a 100 gallon tank for my red ear slider turtle
Answer: Yes. I use this for my CST in a 55 gallon tank. This is a great filter. Remember, it is more about the media you use than the filter alone. Experiment with media to see what works best for you. For my turtle, I have found that layering sponges in the bottom tray from coarse, medium to fine and then using Matrix bio media in the next 2 trays and then using carbon and an ammonia neutralizing carbon in the last two trays works wonders. It really keeps my turtle tank clean. This filter is easy to use, prime and clean. Plus it is very affordable. All canister filters are basically equal, the media is what really matters.
Question: Will this include an installation manual and all the tubings? I am new to canister filters and I want to know as much as possible before purchasing
Answer: Yes, though you would do well to check out some YouTube videos demonstrating the setup, as well as the steps to take to disconnect the unit from the tubes for cleaning. The manual that comes with the filter is a great start, but a little unclear at times.

User questions & answers

Question: can I order the media basket the filters are placed in
Answer: yes I believe you can order replacement baskets from Amazon.
Question: Hello. is there sunsun hw-304b 220v
Answer: No
Question: Does anyone have a problem getting this to work in a tank that isn't full? I filled the tank to prime then removed water & it stopped working
Answer: You definitely want to pre fill the filter before starting it up (if you cant prime it hoses might be mixed up-suction return lines) I would also make sure the return tube is fully submerged at the top of the water. I personally have three 304b filters, one of them gives me issues like yours if the outlet tube isn't covered with water.
Question: How do i know if my uv light is working? i put the filter together recently but i don't know if the light is turning on
Answer: There's a little round button nest to the on off switch. It is actually not a bitton so dont press down on it. It is a window that will show when the light inside the filter is on.

Product description

The new 2016 SUN HW-704B external aquarium Filter system utilizes a multi-stage approach to filtration. Filtering aquarium tank water through four internal layered baskets filled with assorted filter media material provides extremely thorough biological, mechanical and chemical filtration. This canister draws water into the filter through an inlet tube and returns crystal clear water via an outlet tube (both supplied). the outlet tube is fitted with a spray-bar to help increase oxygen aeration levels within your tank. These filters are absolutely ideal for freeing-up space within your tank and provide a huge internal capacity for filter media, making them suitable for larger volume tanks. The four flexible media trays allow you to add other filtration media such as SUN activated carbons, ceramic rings or bio-balls (sold separately). by filtering your tank using the filter media, you will observe a vastly improved level of waste-free water through extremely strong biological purification. The filter's easy-access layered filter media basket's make it simple to customize your media choices to suit your aquarium and fish livestock needs. The built in UV sterilizer exposes passing water to lethal doses of Ultraviolet light, killing, sterilizing or otherwise irreparably damaging many micro-organisms. Your fish tank water is pumped past the UV light which is sealed inside a quartz glass sleeve which is designed to allow the maximum amount of UV to pass through the water. Maintaining the filter is very simple. The drip-free shut-off tap allows you to remove the filter and transport It away from your aquarium fish tank to an area more suitable for cleaning. Each filter media basket lifts smoothly out of the unit and can be easily rinsed through and returned to continue its operation.

User questions & answers

Question: what is the tube ID dimension
Answer: With hoses attached it would be very, very tight if it was me I would not use this cabinet. You need no less than 22 to 23 inches in height.
Question: I live on the 2nd floor in an apartment building. We have frequent power outages that last from 2 seconds to .5 hour. Will this leak all over
Answer: Yes it does but you must use the internal pump for the sterilizer to come on .
Question: Why can't I find sunsun 704b replacement parts
Answer: I put the bio balls in first. then the ceramic. finally the filter pads in the same layer. i only use 3 stages leaving room for something else like carbon bags. i love mine it works great.. very quiet so when you start to hear a very minimal hum coming from your tank it is time to clean it. and finally make sure you have a towel with you when cleaning it you will lose a very small (2-4 ounces) amount of water when you disconnect it.
Question: What is different from the sunsun hw304B? Other than the shape of course
Answer: No, the flow can't be adjusted. Actually it doesn't even have a power switch but turns on by unit being plugged into electrical outlet

User questions & answers

Question: Where do you find a replacement for the O-ring on the lid
Answer: Yes, there is an instruction manual in the package. The RUN button and the +/- buttons are for skimming use. The WAVE and FEED button are useless.
Question: What is the inside diameter of the hose
Answer: 150 will be fine. Thanks.
Question: I only received one clamp, can I still run the unit until I get a replacemrnt
Answer: I had too watch a lot of YouTube videos.. You want to have the bubbles come up to the bottom of the collection cup.. Ensure you control the output by rotating the blue handle. Also ensure that you you have the water level correct. I have mines set in 7 inches of water. Once I got all those parameters set, it has been working like it should. You will have to keep adjusting it until you get it.
Question: For replacement media, does anyone know the model number of this filter? Want to ensure the availability of replacement foam for this filter. Thanks
Answer: Full load operation would meet the needs if there is not much biology in the tank.

User questions & answers

Question: Does it have a Siphon
Answer: Unsure what you are asking for here...a Siphon is not included but the pump is self priming, also the inlet/outlet tubes connect with a "toggle" bar which allows you to remove the inlet/outlet from the pump with no mess for cleaning of the pump. I have this for a 75 Gal tank and it is GREAT!
Question: Where is the company email? I am missing 3 parts with this filter
Answer: Check your order history for the seller
Question: What's difference with sunsun hw303b
Answer: No difference at all....just the name
Question: Why does the description say this product is only for fish, not turtles
Answer: Any of these canister will work for turtles. My red ear sliders are happy as can be. You just need to clean more often if you are feeding them live food vs. pellets (or if you over feed). I throw a powerhead on the bottom of the opposite side and corner of intake to keep the dead spots clean and water circulating.

User questions & answers

Question: Does it have a UV light
Answer: No it doesn't. I haven't found a UV light necessary for my pond setup. It is outdoors, in the middle of the Pacific tropical climate.
Question: Will water be crystal clear
Answer: Water will be clear when you first start it. Depending on what type of marine life you are housing will be how clear the water remains. I have an eastern painted turtle and the tank needs to be cleaned monthly because they are dirty reptiles. I imagine that fish are much cleaner and the tank can be cleaned less frequently. But you still need to do periodic cleanings according to the instructions.
Question: Does this come with filter media
Answer: Hi Mark, yes, it comes with all the necessary filter media to start it.
Question: Where to check the model number
Answer: Hi Ronald, If you are looking for the model number on the filter itself, you won't find it. There is a label on the side of it though, near the top, with information about the filter. If you provide me with that information, especially the wattage, I can give you the model information.

User questions & answers

Question: Will this be good in a 40 gallon breeder tank ? With sand ? Or should I just stick with 2 power filters
Answer: I have two of these filters and I use one in a 55 gallon tank with pea gravel and it works perfectly. The other I use in a 100 gallon indoor pond and the water is crystal clear.
Question: Can you use this filter for lower water level tanks such as turtle tanks
Answer: I use this in my 55 gal turtle tank which has about 7" of water in it. I had to tape up the intake pipe joints to reduce air leaks and I had to manually prime the intake line to get it to start but it does work fine once the siphon gets started. I'm going to drill the tank below the water level and convert it to gravity fed because it's a real pain to get started due to the vertical distance the water has to travel to leave the tank.
Question: Can I use this in a half full tank? I have a 20gallon long breeder tank a little over half full, about 11 or 12 gallons
Answer: There is plenty of power in the pump but you will have to make some modifications to the fittings in order to extend the height in the tank. I set mine up for turtles and was able to get the water level 5 inches below the rim with the firings provided.
Question: Can I use this on a 45g reef tank
Answer: Yes it will work. But canister filters will harbor nitrates if not cleaned every week. A good protein skimmer and good water flow is much better for salt water. I would recommend a hang on back filter just to clear the debris and clarify the water as needed, it doesn't have to run constantly. Canister filters are not needed for reef aquariums. I bought this canister for my freshwater fish tank and it's decent for that.

User questions & answers

Question: does this come with activated carbon foam/media
Answer: You can find it on amazon
Question: Does the heater have its own power source? In other words is it independent of the filter. I want to be able to hook the heater to a temp controller
Answer: 5/8
Question: hi I’m having trouble with this filter. It’s taking in air and it’s starting to make weird noises. who can I contact for warranty help? Thank you
Answer: You should be able to for a short period of time. After you softened the tubing and placed it on the tubing, it will harden slightly and create a nice seal. The clamp is a safety precaution in case you do not install the tubing properly. You could always zip-tie it till you get a new clamp.
Question: My unit is constantly purging air. Is there a solve for this issue? I recently bought mine just a week ago
Answer: Forget the pre cut filter pads! Go to your local home improvement store or Walmart and buy a chunk of blue cooler pad for a swamp cooler and cut it to fit! Then hit any fabric stores and get a roll of polyester quilt batting! Cut the batting to fit and it works just like regular filter floss for aquariums. The blue cooler pad material will last at least a year or more before it starts packing down. The polyester batting can be changed as often as you want to change it. Do make sure that you only buy the blue cooler pad material as the green ones have formaldehyde and will kill your fish. The blue one is a coarse polyester material and works great in tanks. I use both products in my sun sun filter as well as using throughly washed lava rock as my main filter media. Works great and is cheap to source.

User questions & answers

Question: Would the Finnex PX-360 be able to handle ~12" below the tank top and, in addition, host an in-line Hydor 200W heater and in-line DO!Aqua CO2 atomizer without lowering flow rate too much
Answer: To anyone else reading these response: 1 - The filter does not self prime, you have to fill it with water through the priming port on the top of the housing. 2 - To the original question this is exactly how I run it without the CO2 in atomizer. Not sure how that would impact the flow. But I run a Hydor 200W heater in line and the filter is ~ 3ft below the water line. I didn't want a fast flow and I had to put a valve on the output to slow it down. Should have no problem with flow on a 10G tank.
Question: where can i get parts for this filter? i need the cap for the primer hole
Answer: Take the pump to Lowe's are any hardware store... What you looking for is a plug that has a bolt in the middle of it. If you ask the hardware store they will know what you want. Just make sure you take the pump.
Question: Does this filter include long hoses so that it can be mounted under the tank (in the base of the tank)? Or is it designed to "hang on the back of the tank only
Answer: No. only 2 short 24" hoses. Get some 1/2" ID 5/8" OD vinyl tubing. It fits. I put some on today but need to get some elbow joints. They do not give part to make a U over the top of the tank so I am going to have to build one myself. The canister itself is just under 9 inches tall but allow several inches to bend the tubes backwards an run them up the back of the tank. The pump itself can handle over two feet, I think mine is closer to 3 feet of lift and is only half open.
Question: what is outlet gallon-per-hour flow rate
Answer: Daniel:Gallon per hour flow rate is a measure of how much water goes through the filter every hour. You ideally want to circulater the water in your tank about 6-8 times per hour. So, if you have a 10G tank, you want a flow rate of about 60-80 GPH. The Finnex is advertised at about 95GPH.Unfortunately, most manufacturer's rating are hard to understand. Sometimes they are measured without any filter media, so the filter is just circulating water, but not filtering anything. Others measure their flow rates more realistically. So beware of relying on manufacturer's numbers.....The Finnex is suitable for 5-10G tanks. Some people say it will work for 20G tanks, but I think this will only work if the tank is lightly stocked.Hope this helps.Gautam Bose

Reposition or remove the media separator, and snap the halves of the media container back together.

User questions & answers

Question: How long is the spray bar end to end
Answer: I own the biomaster 350 and 600. I haven't cleaned them in 4-5 months. And when I do, I only have to pull the pre-filter out to clean it. the majority of the gunk is caught there. So in answer to your question this unit does not have activated carbon, but you can buy it and fill one of the filter trays with it. It comes with 4 stage external filters with biological, mechanical and chemical filtration and a pre-filter. The trays are large. To be honest this is a excellent external filter. They may cost a little more. But get what you pay for in this case.
