I ran HOB for years. They are fine. I still run them on quarantine and small tanks. I run canisters because I like the silence, the aesthetics of not having a big plastic box hanging off the back of my tank, smaller cutouts in the lid helping with heat retention, evaporation, and jump prevention, customizable flow direction, and once a year cleaning. I also know that no one method is perfect. Do what you want. Doesn't matter to me!😃

Ok, so I've had canister filters my entire aquarium life... :) Since 1983. Now, you have me rethinking that. My aquarium is very near to the back wall, soooo... having the filter system under the aquarium saves space :) 2:38 No filtration needed? (';') ? and I do have lots of live plants in my tank. But wait, it's a Ferrari? or It's for arrogant aquatic enthusiasts? Under gravel filter? I like the sound of that! I'm solar-powered, so the energy isn't bad. I'm worried more about the heater that I run and how much that's consuming. Thanks for this video, now I'm not sure how I feel about my filter system. But since I already have it, I guess just go with it. In closing "no perfect filter" ok, thank you. This was a great video! Stay awesome!

[@feliciaheater5548]

Thank you, Cory. I was getting back into the hobby after 16 years and I was on the fence about using a canister filter. After seeing this I'm not getting one.

[@TexKP]

I think the problem with the hobby is there are too many elitists who think they’re geniuses for blowing all their money on gear. As a result, they have a tendency to pressure others into doing the same. At the end of the day, a filter is only sifting particles out of the water column. Having a balanced aquarium means you don’t need tech to keep your fish alive.

[@markreutz]

I've got 2 Eheim Classics. 2215 and 2217, one of them running for almost 10 years. Classic, one of the most reliable out there. I got them running on 2 planted tanks, and hooking them up in an in line CO2 makes the setup look cleaner and efficient.

[@probablypondering1657]

I think you should delineate between just keeping fish and aquascaping. If you want a pristine high tech aquascape like you see on social media, a canister filter is by far the best option. We understand it’s not a panacea and often unnecessary, but using your car analogy, sometimes you don’t need to just get from a to b, but you may need to do it as fast as possible. In that case you would want a Ferrari

Canisters are great, they are pretty compact and quiet.

They are hard to clean, expensive, use a lot of energy and therefore also create a lot of heat, most of the time are not needed, and can leak ruining your floor. Other than that they are OK I guess.

[@LJMayhew]

Some people have no option but to get a canister my 800 liter tank is braced all the way around apart from the corners, being in the lounge an airline filter would be to intrusive. I had to have a JBL greenline 902e due to my low cabinet it's the only canister I could find that had 90° in/outlet. I get plenty of gripe from forums about the low turnover of water, but it is a jungle tank and the canister is simply there to move water from one end of the tank to other.

[@travismorgan9273]

@@LJMayhew Every aquarium is a little bit different but for the most part turnover is over rated. Some of my best aquariums have no flow at all. Truth is a lot of plants and fish don’t like fighting the current all the time. Some think you have to have flow for the heater to work also. If you mount it horizontal almost touching the gravel, the heat from it will create flow. Hot water rises, slowly cools off and falls back to the bottom, starting the cycle over again. I turn the heater off in the summer and still have no issues. Maybe you have fish or plants from fast moving streams that can’t live in an environment like that. Maybe a tank is over stocked on fish and doesn’t have enough plants. Maybe someone feeds their fish tons and tons of food just because they enjoy it. I don’t know every situation but so so many planted tanks are over filtered and have too much current. Too much current and over filtration cause their own issues. Everyone thinks they need it and people who sell aquariums make money on filters.

[@lorddjg]

I use all kinds of filters. and my fluval cannister filter is by FAR my favorite

[@kamenidriss]

Totally agree with this view, with one caveat. When you're doing larger aquascaping focused tanks, canister is the ideal filter. It doesn't de-gas a lot of the CO2 we're injecting (unlike a HOB, for example), looks discrete and tidy (vs. a sponge). and also it provides good amount of flow around to bring around the CO2 bubbles.

[@kylelaughinghouse1893]

That's why I run inline diffusers with my canister filters and put the co2 diffuser inside my hob

I run all sponge in my fx6 and also have a medium density prefilter sponge essentially making it a big sponge filter. My water is crystal clear and my fx requires minimal maintenance.

I have planted tanks.....and I switched from canister to HOB just to polish the water.....still siphon the bottom part of the aquarium. One caveat I have with canister is that it is messy and smelly sometimes when you clean it. I rather just get a small bucket and clean the sponges from HOB and let the plants take care of the rest......works like a charm. Great video..keep rockin.

[@Anubis30224]

Made a fish friend IRL, today. Both bonded over your products for a bit. Cheers!

[@FusionDeveloper]

I run a sponge-filter + a DIY canister filter that uses siphons and 1 super tiny weak 1 watt pump (yes, 1 watt, i measured it). If there is a power outage (or any reason for the pump to stop), the water levels just level out. Flooding isn't possible with my design/setup. I'm mass-breeding snails, shrimp, dwarf top minnows, a million floating plants and micro-organisms, just for fun. My bio-load is insanely high. The water is tea-colored and a little cloudy and everything is thriving on over-drive. A hang-on-back filter would clog instantly. Having said that, my setup is NOT at all normal. Most people have a 1-20 fish/creatures in their aquarium and pretty much anything would work for them.

[@dtt719]

If I had a fish room and was running 40 tanks I wouldn’t use a canister, but my focus is on having one mid size (43 gallon long) tank that is heavily planted and aquascaped. I want to see as little equipment as possible in my tank and I also like it to be as quite as possible. Sponges would not only be an eyesore but limit hard scape and plant amounts/placement. My ideal would likely be a sump, but a canister for me works well enough. The canister I use has a dc pump with adjustable flow strong enough that for now I don’t see the need for an extra power head. I think the question really depends on what you care about in the hobby. If you want to work towards a pristine display tank like those IAPLC then you kinda need one or a sump. Sure you could try and use sponges and hobs and take them off to submit your competition photo, but if you’re going through all that work making an aquascape (plus the cost) why would you want to see sponges day in and day out in that tank

[@joshuaburch4908]

My #1 reason for an FX is the easy water changes. Being able to hook up a house through a quick-connect, pump 20% in a few minutes, connect the hose to the spigot, fill up and I'm good to go.

Love extra long maintenance intervals as the amount of fish is nowhere near the filter's capacity. The hoses do look "cooler" to me than the big box on the back of the tank. Never considered buying one because the one I got is $200 (Ehiem Pro 4) and a HOB was working fine.

[@patrickkerr329]

I think Corys point is do your own research and find out what’s best for your setups. I run canister filters because I’m not too worried about the upfront cost and monthly electric usage. I keep all my aquariums in my office and the sound of running water is very distracting, canister filters are silent. So the decision was very easy for me.

[@bravehearts1986]

[@AlgaeWhisperer]

great video ! .... makes me think twice about replacing my HOB ... lol ... thanks so much for sharing

[@UncannySense]

I'd take a canister filter over a HOB. The biggest benifit of a canister filter is the increase in total water volume. Also I don't use the inbuilt impeller pumps on my canister filters but run a DCT/DCP sinewave pump inline which is about 75% more efficient and near silent, so the canister pump is only a backup...Never had any real issues with canister filters and If i was running a barebottom tank its the first filter type i's use.

[@cajanir]

Good discussion. Canister filters look cool, but I've always struggled to find a scenario where I'd really need one.

[@cut419ram]

I've never used a canister so I have no reference other then what I've leared about them via others. From what I understand they help filter better so less water changes are needed? Not sure if that is correct though because I have no first hand experience with trying one on an existing system I have to see if it makes that type of difference.

[@TexKP]

I totally agree with the sentiment behind this video, but there are always a tank or two where I enjoy geeking out on the tech. I bought a used 150 gallon tank with a sump that got me even deeper down that rabbit hole until I’ve decided to switch to a canister. Under certain circumstances, I’m still sold on the benefits of higher water flow and the larger volume of filter media. It gives you more freedom to get lazy on cleaning out the sponges. Unfortunately this also paves the way for bad maintenance habits. Also, if you use fine filter sponges in a power filter, the water will start flowing right over it in no time. It’s the same issue with sumps, though.

[@InfamousTanks]

I tried the cheaper way to start. Sponge, hob, and finally canister. The canister by far has my fish looking like they are floating in air. I have 20 ppi, 30 ppi, 40ppi, 50ppi, floss. then my bio media. It’s probably overkill for some but my peacock cichlids and haps can be a little dirty so this works great for them

[@ashleydre5153]

I got into fish after raising a turtle for 20 years. Back in the day, after those first few HOBs failed me, I went to a canister and eventually added a sump. But canisters kept my turtle alive for over a decade so they are what I knew and loved. I’d say turtles are kind of the use case for when they make most sense. They don’t take up a substantial amount of swimming space, there’s less equipment sticking out of the tank for them to climb onto, and (if you get a big one) they add water volume with nice strong flow for removing the copious amounts of turtle waste (and they’re psychologically easier for people to understand/deal with than sumps…but I love those too!). So, all of that is to say, I have a canister (and a HOB AND a sponge filter) on my 40gal community tank and I’m not ashamed 😂

[@Eric-xx3mb]

I love this channel and I respect Cory so much. He obviously knows a lot more than I do, but here are a few reasons I sometimes like a canister filter. #1 it's out of sight. With the filter below the aquarium in a cabinet it's out of sight and quieter. A HOB will be more visible and potentially louder. #2 the cost isn't a big deal. If you have a $1,500 aquarium (fish, plants, drift wood, heater, air pump, etc) $100 to $200 for a canister filter isn't a lot of money. For example you can get a Marine Land 220 and it should work up to about a 75 gallon tank and it's less than $90. #3 the inlet and outlet take up less space so you can push the aquarium/stand closer to the back wall. #4 you get better overall tank flow with fewer dead spots because the inlet and outlet are in opposite sides of the tank. An HOB puts the inlet right below the outlet. #5 the larger canister space gives you more room for sponge filets, filter floss, etc. I only find the cleaning of the tubing to be extra work over an HOB. Overall I prefer HOB, but canister has advantages nonetheless IMHO.

[@softaco3088]

Hard to go back from a canister once you get used to the ease and benefits of owning one. They are quite, have more media room, better flow, they don't need cleaned or replaced as often. Also, think of all the attachments: Spraybars, UV's, skimmers, etc. Why would I have 4 HOBS + a skimmer and whatever else take up all that space when I can just have a cannister do the same thing that isn't looking ugly sitting on top of my tank or taking up tank realestate. Cannister is the future, hob is the old. Hobbies evolve.

[@talex001]

a little over a month ago I switched to a cannister filter (Fluval 407) on my 75gal, it's a heavily planted tank, it also has a pretty heavy community fish load in it - the tank had been running for about a year and a half on a single in tank filter with just sponges as well as a HOB cartridge filter and it has been fine but I don't think I would ever go back, I do see better water clarity but the difference maker is I checked the filter after about a month and I estimate I can go 3 or more month's before cleaning it where with the old filter setup it was at least an hour weekly, sometimes twice a week - this is much more set it and forget it, time will tell but even if I had to clean it more often, it's much easier to clean and aesthetically looks much better and is much more silent. That said I also have 29 and 10 gallon tanks which I use HOB for and I feel no need to change those.

[@VanNguyen-ns6ck]

Very valid arguments. The reason why I'd consider a canister filter and a cheap branded SunSun one is because; (1) I'd like the convenience to clean my filter once every 3-4 months as oppose to once every 1-2 months for a HOB, (2) I don't have the depth space in my living room and do not like the look of the gap between my tank/stand and the wall, (3) Canisters are more quiet, easier to customize with media and do not require priming after power loss (depending on HOB compared to), (4) Like you said; it just looks cool and I want to own one so I can say I have a canister filter even if it's a cheap one.

(i was rehousing the koi every 3-4 years to people i knew who had pond)

My canisters het cleaned every 4 to 6 months and sponges get cleaned every month

[@fengxueshanshenmiao]

There is now a very popular trend of relatively new filter design in east Asia, namely, "turnover box filter". What's Cory's thoughts on those?

[@thiransamarajeewa6753]

I use top fliter and Sponge filters because i vot glass roof. And its cover all around the tank. For African cichlids the fliters are doing well. By the way need to maintain each and every month ny 75 gallon tank

Naughty Cory!!!!!!!!!

[@potatoesorsomething]

I run mostly sponge filters because of how easy and better they are for my fish (they need slow flow). Ive got only one canister on a 45 gal.

Hello sir, I hope your health is good. I accidentally washed ADA bio media before using it. I pulled out my old media and replaced it with this ADA bio media in my existing goldfish tank. Sir, is there any problem? Will this work or not? Please help me.

[@AquariumCoop]

Watch for ammonia spike but it'll catch back up in a few days most likely.

[@badenough6109]

@AquariumCoop thank u, sir.....now i feel relief

@@AquariumCoop can add my old media with Ada bio Rio media for their bacteria boosting?

I've got a 250l tank full of platys 1 angel fish and a musk turtle. I have alot of plants in the tank, loads of hornwort, corymbosa, amazon swords and java fern, that's had loads of babies also plants growing out of the tank, like pothos, spiderplants, palms, and a maiden hair fern... I bought a good canister filter because the tank got so dirty even with the plants in. with a hang on the back filter just didn't clean the water enough.. the turtle is a baby, it gets fed the appropriate amount every day. Then the fish get fed every 2 to 3 days. Without that canister filter since my back injury, I wouldn't be able to maintain the aquarium at all.

[@sf49erswarriorsgiantsgumba99]

Canister filter is needed to where you really do need it, especially in an aquarium over 100 gallons with tons of fishes. Putting multiple HOF in an aquarium that big, you’ll need atleast 2-3 of them. There’s so many reasons why you need a canister filter!!

[@haitch04]

I bought a cabinet aquarium that came with a canister filter and I got the store to swap the canister for an internal filter. My main reason is that physically I'm not good these days at getting down on my knees and rummaging about in the cabinet. I would say the canister has many advantages though e.g. it holds a larger area for bacterial growth, it can house your heater and it can run an inline CO2 reactor which is the best form of CO2 addition, while keeping all this outside of the aquarium. So I'd say, internal for convenience, Canister for cosmetics.

[@davidcarroll7143]

I have a 55 gallon 2 hangons, and aSun Sun all collecting dust.and a sponge filter, had a few large fancy goldfish, a couple of corys all fish that lasted for a couple of years. everything fine , then dropsy probably from over feeding. they all slowly died. Im setting up the tank again. But then reminded of the success I had many years ago of using under gravel filters. 2 75s, 55, 40 no problem. Im now learning of dirted tanks and plenum. I've never had a planted tank. But want to set up a tank of peacock cyclids and or community. Help me get back into the Love of fish I had the plenum didnt know what it meant.

[@ForbesExotics]

Do you think a canister would do good for a snapping turtle enclosure

[@Dayzyhazy]

My mom bought me my first canister filter today as an early xmas gift and iv been looking at them for a while because i have fish the produce a large bioload but she bought it for me because it was on sale

Thank you!!!

[@brianmizway9324]

Thinking of getting a 125gal this year. Ive been drooling over the fx6 for awhile but still not sure if i want the wearable parts issues or any leaking issues over time. So i can either get 2 fx6 for the 125gal or 3 tidal 110 hobs instead. Still not sure yet.

[@Jhholderfield]

I have a heavily stocked 75gal and I run an fx4, tidal 110 and a co-op sponge and that’s more than enough.

[@mattsdmf367]

I want to make the switch from a canister to a HOB in my tank so badly because I dread the maintenance on it, but I’m fearful about making a change because I have flow/co2 dialed in with my inline diffusor. I’ve only got a 20 gallon aquarium but I’m dosing EI dry powder daily and running high light/co2

[@andrewwhittaker2908]

Im successfully running my 125gal on 3 hob filters and 2 sponge filters. Way more than i need i know. But i used a canister forever till it croaked. I HATED every minute of it. 😅😅😅 especially priming it.

[@Pierceprepper327]

I like my canisters for the flow rate and the ease of directing the current how/where I want it. I get a powerhead plus filtration is what it boils down to. But anything below 20 gallons a canister is overkill

Question 5ft tank and 1 midads what filter would u recommend?😊

[@aquariusmoon771]

Idk what midads is but I have a 135 gallon 6ft overstocked cichlid tank and I use a Fluval FX4 and a simple sponge filter. Before that, always had problems.

[@jeffreypassfield7218]

I got a canister because i had sumps and a canister for me is easier to maintain, the fish i keep like high flow and because i like them. Each to their own i reckon

[@adityasanyal1678]

Writing this sitting here in Delhi, India.....for me, it's mostly been a choice of what's available here. Canister filters, as of now, aren't made here so getting parts and media is prohibitively expensive. There, that's an automatic disqualification. We also mostly live in apartments and single floor homes here unlike America where suburbia is dominant. So that automatically makes very large aquariums a no-no. One advantage that we do have is that all the dust laden air (from the vast agricultural swathe that surrounds Delhi) automatically makes a planted aquarium far more effective by injecting infusoria constantly. The only bad thing is the otherwise polluted air, about which you can't do much with any kind of filter, except a real time monitoring, very high tech system which has all sorts of chemical scrubbers to scrub pollutant gases and their electrolytes in the water!!! Sponge filters with brown gunk which isn't cleaned that often, along with some version of a fluidized bed is what works best here. I reckon, you are right when it comes to buying stuff....if I had a thousand dollars to spend on accoutrements, I would have bought a canister filter, even for my 20 gallon tank. But a gradual approach to introducing fish, plants and other infusoria in the tank along with gradual investment in larger or more complex filters (as the bioload rises) is probably the best option. Patience was not a virtue I had in dollops when I was starting out my tank (and both I and my fish paid for it!) but it is probably the most valuable accessory that an aquarist can have access to....bar none!!!😅

[@Esther-gj5hs]

I’m not sure if you get those in the US but to me the best filter is the Juwel Bioflow. The only downside is that it takes up room in your tank but it’s easy to hide behind plants or decor. It’s quiet, has modular filtration, the water stays inside the tank, no tubes, perfect if you don’t have an aquarium cabinet to put a canister. 😁

[@Sec_coach]

Well if you can’t have a sump have a cannister unless it’s for a beta The cannister are amazing filters when you start with filters like these you won’t go back to hang on back filters

[@shreyasasodekar8465]

Can we keep canister fitler at the same level as thst of fish tank ?

[@adkent9]

Not really. The filter needs to be below the water level because the intake is gravity fed. Water needs to flow down into it.

[@RoeJogan]

Amazing Video! Thankyou!!!!

[@philipocarroll]

I replaced an internal filter with a canister and lots of plants started melting. Traced it down to the phosphate pad in the filter, sucked all the phosphate from the water (I had very few fish)

[@01cruzer]

I ❤ my oase bio master 600 best decision I ever made

[@BJD12thDoctor]

I recently bought a Juwel Rio and this company builds their aquariums with internal filters stuck to the glass with silicone. I plan to leave that as is, (I did not follow their directions on filter medium content as I left out some of the sponges and white pads and instead added a lot of ceramic filter medium) but a lot of people remove that internal filter in favour of a canister because of convenience. You may know Nickey, she's become quite an authority on fish keeping in The Netherlands, has a video about removing an internal filter from a Juwel aquarium. As for me, for now I think the internal filter is more convenient for me. I can pull the filter contents out, give them a rinse in a bucket and put them back in. Canisters can be heavy, sit on the floor and I'd have to drag them to my bathroom for cleaning as I can't have all that on my carpet. So far, the internal filter produces a powerful outflow. I'm wondering how the fish will like it once they're here.

[@MHF22]

For me its preference. I heavily plant and therefor do not need the filtration capacity they offer, om sure all my tanks wpuld benfone woth sponge filter. Being said i do not like equipment. A canister filter lets me seperate filtration, in line heating and in line co2 from the fish tank. Nothing dislike more than a stunning aqarium with visible airline times and pipes.
