Fluval FX6 Aquarium Canister Filter Overview & Setup

[@jameshallison]

Hey, thanks for the video! For those of you interested in buying a fluval fx6, I just bought one. Here is my 1hr experience: SUPER easy to set up Extremely Quiet once running. Just the dull hum of a motor This video has three areas where it lacks full info: (1) When they put the canister under the tank and say turn it on, the valves where the in and out tubes go are in the horizontal position. They need to be in the VERTICAL position to work. (2) You unit might run for 30 seconds and then it will turn off all by itself...you will be confused...the unit is only try to get air out of the system and will resume running after a painful 2-3minutes, don't worry like I did. It may turn off and on a couple of times in order to evacuate all the air. (3) If you are going to do activated carbon, its easier to place in the unit before you go through the trouble of getting it all set up. I agree with people that this is expensive, but fluval has great customer service and many replaceable parts as well as a warranty so I expect this to run for a long time. Best of luck!

[@jameshallison]

UPDATE: so i've been using it for 3 weeks now...I can't say anything bad about it. It is still so frickin quiet and the tank looks perfectly clear (110gallon). It comes with jet blowers on the output side so you get good water movement through the tank. I've moved them a couple of times to mix up deadzones/make it more interesting for the fish. Would recommend to something without a tight wallet. No experience with cheaper makes like Sunsun to give a fair comparison.

just got my new fx6. they got rid of the indicator dials on the top of the fx6. they have a hose holder now and they added in and out in white lettering on the lid to indicate inlet and outlet. very nice to have. I like it better with this design. good job fluval.

[@ice.3000]

my left ear thanks you for the information

[@alltankedup]

This filter is going to make my life a hell of a lot easier. The tank I got that’s 12 months old has two sponge filter and a really loud cannnister filter.

[@garymeilak]

I've had mine for 6mnths now and had no problems ,very good filters

[@JayOrlando32828]

I bought my a few days ago and set up yesterday Monday Feb 5th and what a great difference ... super quiet, the set up was so easy, got caught when I turned it on and suddenly it stopped lol I unplugged and plugged it back in .... the it turns off on it's own again !!! Then I remember this thing is now "smart" lol oh wow .... I left it alone lol it works wonders removing the bubbles from canister to minimise noise, etc .... any how ... I like it ... I had a marineland 350 (very noisy)

[@JulesAskalotl]

love this filter!!!!! IT's amazing! Being my first cannister, it's been such an easy filter, and so self explanatory.

[@fluval]

Good stuff! We feel it is very intuitive filter to set up as well, we are glad to hear you appreciate the effort that went into it!

[@goodall1bay]

I used the fx5 for years, great canister filter, probably the best of its time. Everything was well made and the motors on these Hagen machines are robust and long lasting. I used mine on marine aquarium and installed my own media. I added carbon and bio media and wool. I imagine you could us it as a sump pump, I don't see why not.

[@heathchavez9906]

there was a loose o ring on the bottom of the inside of the filter. dose it go in the grove in the bottom of the inside of the canister? and yes the lid dose have its o ring on

[@DLMyth2]

This must of been an early design of the cap of the FX6 since mine doesn't have the dials to set the month I set it up for cleaning.

[@fluval]

Correct! There are two generations of FX series filters - the first generation has dials on the top, whereas the second generation has clips to hold the drain valve tubing!

[@evanmarcus2007]

hello, i just finished installing my fx6 and its making some flucking noises and a lot of air bubble in my tank, please help

[@fluval]

It's important to perform regular filter maintenance (media rinsing and replacement) to prevent media from compacting, which can result in air accumulation. Ensure the filter intake is not positioned near an airstone or any other source of air bubbles in the aquarium. Verify the integrity of the intake rubber hose connector that attaches to the intake siphon tube, as it does dry out over time and becomes hard and non-flexible, thus requiring periodic replacement. Also verify that the joint between the intake rubber hose connector and the intake siphon tube is positioned below the water surface. Lastly, ensure that all rubber gaskets and O-rings have been cleaned and lubricated with Fluval Silicone Lubricant (Item #A325), and that there are no kinks, loops, bends or turns in the hosing.

[@nissan300ztt]

I too only found the ceramic rings and no carbon media. Are we suppose to buy more media for chemical filtration?

[@fluval]

The amount of chemical filter media depends on the aquarium volume and the particular pollutants, etc that you may have to remove. It may be necessary to purchase more of this type of filter media.

[@nissan300ztt]

FLUVAL Aquatics I added the biochem stars 20 Pack and a package of nitrazorb. Its going to be on a 125 gallon koi tank.

[@mediscusnut7994]

[@fluval]

Hi there! You can safely reduce your FX6's flow by up to 50% by turning the output AquaStop valve. 👍

You can feel and see water flow but how strong should the output be, I just want to make sure it's at its maximum performance

[@Kenney9120]

+zac logan A general rule of thumb is five to ten times the tank's volume per hour. However, the correct flow rate depends on your tank's needs. The best guide is to monitor your water quality and adjust the flow rate as needed. Also, take the size of the fish into consideration and make sre they can not get sucked into it and injured. :)

[@fluval]

+Kenneth shaheen jr. Hello! The best guide is to monitor the water quality with regular ammonia, nitrite and nitrate testing. Also, ensure that the output nozzle(s) are moving the surface of the water such that it is being well oxygenated.

[@vardanrathi7777]

Can it be placed beside the tank instead of bottom?

[@fluval]

Hi there! Yes, FX Series canister filters can be placed beside the aquarium rather than directly below it, provided the distance between the top of the canister and the water level is more than 8" / 20 cm and less than 59" / 150 cm. For the best filtration performance, ensure the hosing follows as straight of a path as possible, with no kinks or loops.

[@junearienette3081]

Probably a stupid question but I just started looking in to canister filters... Can they drain your tank if there's a malfunction?

[@fluval]

+June Arienette If a canister filter is properly installed and maintained, there is no reason to be concerned about malfunction.

[@gewglesux]

+June Arienette I have heard mixed answers to this question... some say yes- some say no. in my opinion I say no. If the filter is filled with water I don't see how the tank water will be allowed to escape. I have an FX6 I just keep in in a plastic Rubbermaid container incase of a leak... so far so good. Canisters are a good way to go.

Terri you can safely dial down the output by using the output valve on your filter, it will not damage the pump.

[@MacGrump]

I just set this up in my yellow bellied slider’s tank in 30 minutes. I’m actually shocked how easy it was to do (and I am rubbish at anything technical). I can’t tell you how delighted I am with it. I’ve had serious issues with a much cheaper brand that just hasn’t been doing it’s job. Set this up and 2 hours later I had a crystal clear tank and a very happy turtle. It’s well worth the cost (I hope).

@@ch1m3ra42 Phenomenal! We had one ‘yikes moment’ when it stopped working 18 months ago, but I managed to clear a lot of muck out of the fan and it immediately kicked back into life.

[@toddt6730]

Would that be good for 125 Gallon Oscar tank?

[@fluval]

Absolutely, the FX6 is a great choice for that type of tank!

[@TheSound0fLegends]

mechanical on top, bio in the middle and chemical at the bottom. Is the bottom basket the last layer before leaving the filter? Ie does the water flow from top to bottom then out? I want to add some fine filter floss to polish at the last stage. Thanks loving my new filter.

[@fluval]

The flow enters at the top and flows down through the media where it is pumped back to the aquarium.

[@antwilliam67]

It says the filter pumps 925 gph and that it filters 563 gph. So after the water is filtered through media at 563 gph does it make its way back to the tank at 925gph?

[@fluval]

Pump output is measured at the pump output, not at the tank. Filter flow rate is what is circulated through the filter.

[@Methodical2]

Mine is setup a bit different than stock. I have biological media in all the trays. I use Seachem Matrix (a total of 3.5lbs) in the canister. The 1st tray also has 3 filters (course-Black, medium-blue and fine-white). The last tray has the thin Black filter at the bottom just in case to prevent any of the media from entering the pump and 2 Seachem Purigen packs. Additionally, I've recently installed a 90* PVC adaptor to replace the dual output nozzle for a more directed water flow. The filter is used on a 125g cichlid tank and I am quite happy with the filter, despite what the interweb has to say about it. It's been running constantly for 4 years now and quiet as a church mouse.

[@ronnieraju4418]

What is the length of intake & out hose length??

[@fluval]

One length of hosing is supplied with the filter of 3m or 9.8ft, which is meant to be cut in half.

[@madusonkeeper]

Where does O ring go exactly? Do phosphate and nitrite pads go on bottom level?

[@fluval]

There is a receiving groove that is clearly visible on the motor head area that inserts into the canister. Chemical filter media should be kept in the mid to top media baskets.

[@leonbenfield6582]

Hi there I have a cupboard space of (H)23"x(W)15"x(D)17.5" Would a FX6 fit?

[@fluval]

Hi Leon, the FX6 has a height of 23" so this might make it a tough fit. fluvalaquatics.com/ca/product/A219-fx6-high-performance-canister-filter/#.VGvFIPnF81I

[@elyh777]

Question? How does the water travel through the filter? I can’t seem to find a vid that shows or explains how the water is filtered. Just want to know so I can stack my media. Thanks

[@fluval]

The water enters the outside of the media baskets, then traverses the foam surround media upwards to the top and then downwards through the media baskets, at the bottom of the media basket stack is the chamber that leads to the pump intake. The pump then pumps upward through the included inner canister output tube.

The ID of the ribbed hosing is 15/16ths and the FX6 rubber grommet connector is 1 inch.

[@mariapapademetri9297]

Is this going to be to big for my 45 gallon tank with goldfish

[@fluval]

Hi Maria, goldfish are dirty fish therefore it is a good idea to provide them with a more powerful filter. The FX6 filters efficiently and effectively in up to 400US gallons. This would be a lot for your 45 gallon aquarium, our 07 line of canister filters would be a better option for you! 😊

[@xXxEMOxXx24]

I have discus n plecos with some patties in 120 gallon would this be to strong for them ?

[@fluval]

It will be fine in a 120 gallon aquarium. There are two discharge nozzles which can be directed independently and you can reduce flow the output valve. In our experience with adult discus in aquariums that size or greater no flow reduction will be called for. Most plecos prefer strong water flow. The platys will be ok.

[@nissan300ztt]

So upon hooking up my fluval fx6 the pump leaked profusely. I check the only o ring and it was bent out of shape badly. Causing my prime to be lost and having water all over my floor. Good job fluval quality control. Bad design only have one o ring on the pump to filter canister housing

[@fluval]

We regret your re-installation did not go as planned, however we stand by our effective design. In a recent video, we directly address the pump and show O-ring placement for the FX6. (View at the 5:40 mark) kzbin.info/www/bejne/qXmZaJWVgNF3Y7c

[@Grumpy2004]

I would really like to know how to hook up the Fluval surface skimmer to this or even to the FX5. Thanks!

[@fluval]

Hi Randy, the Fluval Surface Skimmer is great for keeping the surface free of organic film and for helping improve oxygen exchange. However, the surface skimmer inlets are not large enough to allow the required amount or flow of water into the FX6 because its motor is way too powerful. As a result, plenty of air would be inhaled with this device connected on the FX6, resulting in noise and other issues. The Surface Skimmer is meant to be used on the 04, 05 & 06 Series of Fluval canisters or filters.

[@Grumpy2004]

Much appreciated, thank you!

[@nanoaquamania]

looking at so many fx6 videos, i dont understand how does it function, i mean how the water passes through the mid and sides of the trays, as there are 2 pipes and both connect the bottom, thats where the pump is... its confusing.. how would we understand that the water is passing through every sponge and media... also would it really work on a reef tank?

[@nasher1992]

might be a bit late of a reply, I'm running 2 of these and the way they work is the watter gets sucked in the intake and taken to the bottom of the canister them the water flows around the outside of the baskets through the corse foam then when it gets to the top it is forced back down to the bottom through the centre of the trays and exits through the bottom also.

[@nanoaquamania]

+Dan James too confusing, as they should have given a diagram of it. eheim is easy, only downside is it doesnt come with trays. lets see, as i dont know any1 using it here in mumbai india.

[@nasher1992]

it's really not that confusing when see it it, the water goes from bottom to top around the outside pads then back to the bottom through the centre media baskets

[@nanoaquamania]

+Dan James oh, ok got it, sounds cool.. wanted to k ow coz if placing gfo carbon, wanted to know where to place.

[@nasher1992]

you would put carbon in the centre of the bottom tray as that will be last the water hits

[@sandyfriedrich2371]

How often do you have to do water changes with this filter? And take the canister apart and rinse everything?

[@fluval]

Water changes are necessary based on what you are keeping, start with twice a month at 20%. The same for filter maintenance, initially take the filter apart every two months and clean it as recommended, make sure to dose with Fluval Biological Enhancer after.

[@AutopsyEdible]

I have fx6 fresh new tank and water how long take water to get clear, does hose have to be straight up and down , 125 gallon the intake and outtake are in the corners,

[@fluval]

+zac logan Hi zac, that would depend on the source of the cloudiness. New aquariums are often cloudy due to the decor and residual dust and debris that comes with that. Try fine filtration pads for a few days, and if it clears, then remove those pads and replace them. Having straight hosing does help with water flow, as does periodic maintenance of the hosing. Remember to remove the hoses a few times a year to give them a thorough rinsing.

Why is my brand new fx6 loud? Been for hours..... humming loud noise from fx6 pump. Do i wait it out for 48 + hrs or so?

Hi Stewart, the width pump sticks out approx. 3.25 inches, so allow for at least 3.5 inches here. Total width at the widest point is approx. 17.5 inches so allow for at least an extra inch here.

We currently use FX 6's on discus only aquariums in that size range and they have no issues with excess current with the filters running a full flow (you can use the included output valve to reduce flow if desired). In fact discus in the wild originate in many cases in rivers where there is fairly strong water flow, with their compressed physiological body structure discus they are actually very capable of strong quick swimming movement among submerged branches and similar structure.

Do the ceramic media need to go into the mesh bags? I have a new setup (~3 days, 75 gallon tank home of 1 RES turtle) and I see slight white residue/film on the top of the water. Also I am having an issue with micro bubbles, as it seems to be getting air into the system. If I unplug/plug it works fine for about 45 minutes then starts bubbling.

[@fluval]

+dallas lamb First course of action is to always make sure to rinse media well before use. Ceramic media do not have to be contained in mesh bags. It is normal for the filter to eject air; the foam filter media will usually have to discharge trapped air for up to a few days after a new installation or maintenance. Turtles do create more of a mess, and the foods they consume do tear apart while they eat resulting in more surface film.

[@DRLAMB85]

The rubber hose connectors for the FX 5 measure 25.4 mm internal diameter and 32 mm outer diameter. The hosing itself is ribbed and is meant to be connected by those specific connectors. Do note that any external to the aquarium connections should be done only with the bonded rubber hose connector and not with the end where a connector has been twisted onto the ribbed hosing.

125 6 foot tank. How do I set up the outtakes in each corner

[@fluval]

Please watch our recent KZbin video on the subject.

[@rentas1211]

Been having problems with my fx5 for a few months. Don’t understand why it’s new. I have 2 turtles and still the water isn’t clean, it’s cloudy .. I clean the filter and do a 50% water change sometimes 80% water change just so I can get unclouded water.. (once’s a week) 55 gallon tank) if anyone can help I’m all ears.. thanks 🙏🏽

[@fluval]

Jess, turtles which species of turtle and how large? One quick tip to help reduce the amount of organic waste turtles impact an aquarium with is given their very messy feeding habits to feed them in a basin of water outside the aquarium.

[@rentas1211]

I have western painted turtles. And I found out that my filter was broken from shipping. Got it replaced quickly and I’m so happy with the filter now . Beautiful water . No smells!! The water is so clean that it almost look like they’re flying in the tank !!

[@kAi-ub8hi]

using canister for Marine tank, wont it have ammonia/nitrate spike?

[@fluval]

A filter does not cause a nitrogen spike, nitrifying bacteria does. It originates from organic decomposition and the resulting conversion of that to a nitrogen compound or direct input of nitrogen compounds from foods and fish waste. Typically, some associate any added filter as a source of nitrate, however, this is inaccurate. Again, it is the result of biological input and not the inclusion of a motorized plastic unit filtering and moving water. Nitrate is an expected biological outcome controlled by a number of methods.

is the one ring that comes with it an extra one or where does it go?

[@fluval]

+brandon esparsen The large O ring is inserted into the cover, you will see a distinct receiving groove that surrounds the inside of the canister side of the cover. Simply insert the O ring in the groove and ensure it is evenly seated.

[@SundayticketToday]

+Fluval Aquatics do I have to remove anything to see this? I just put the ring around the outside of the rim on the cover the part that rests on the rim of the cannister.

Fluval, according to the FX6 specs, the wattage of this unit at 120v is 43w, however, I am measuring 80-84 watts (using load tester). What is going on? Is this an indication of a near future problem? Thanks...

[@fluval]

We are somewhat confused by your comment, can you explain using a "load tester"? That is used for measuring CCA on batteries.

[@Methodical2]

I use the ammeter/wattmeter appliance load tester where you plug the device into the tester and plug the tester into the outlet and it provides the wattage and amperage used by the device while it’s running, in this case the filter.

[@fluval]

We are looking into this, however, in the meantime please provide some details on the equipment you are using, exact name / brand / model # of device.

I have the fx6 canister for 3 weeks now, this is my 1st tank (120 gallons, african cichlids) my question is about filter cleaning , I see how to do it all but am wondering with the media, the one it came with and I added in another try Bio mass, does this get rinsed or just changed with new media ? im assuming the stuff i have in the nylon bags gets changed to new but cant find any info on media,,, also foam pads it came with, new or rinsed clean ? if theres any info on this please direct me to it. Thanks,

[@fluval]

Hi tim erc, there is a section on Maintenance Media Care in the FX6 Instruction Manual (Page EN-20-21). bit.ly/1bOcXzj Hope this helps.

[@dcd2060]

My unit once plugged in works for like 30 sec to a minute and shuts off?

[@fluval]

It will do that once every 12 hours to evacuate any trapped air. To restart, unplug the filter for a minute then re-plug.

[@casandra-lynncoollidge3680]

Where can I get a permanent mounting hose to screw onto the FX-6 purge valve, I have looked in many places but short of making my own I can't find one.

[@ellyl7219]

Hi, why fx6 don’t have carbon nylon bags?

[@fluval]

Fluval does offer Universal Filter Media bags under item # A1428, they are blister packed in quantities of two per package.

[@andyd7926]

Like to know if these fluval have a leaking problem

[@fluval]

O-rings are incorporated both on the canister and the motor unit, and when servicing the filter, you should clean and lubricate with Fluval O-ring lubricant. Some exceptions do apply so please review and follow the instructions on maintenance and cleaning in your User's Manual, bit.ly/1bOcXzj If the O-ring is not clean and lubricated when re-installing your filter, depending on how you perform the task and also on the particular O-ring design, you could pinch the O-ring. Cleaning and lubrication help prevent the likelihood of this happening. Please note that O-rings are prone to wearing and may have to be replaced.

[@Silvers24]

Huh, I just got a FX6, and it doesn't have that month dial. I'd actually use that if it was on mine. Wonder why it isn't?

[@fluval]

There are two versions of the FX6 - the earlier one features the dials, while the most recent one has clips for the FX Gravel Vac!

[@Silvers24]

@@fluval I see, I personally would have preferred the previous version. Id get more use out of the "feature". I use to want a gravel vac, but due to circumstances and situations. I see no reason to personally own it now. (Still would be a valued addition if I did have it). But for the 300 stock tank I use for my turtle with bare floor. I use those "clips" for my power cord. As I had no idea otherwise what it was for. And failed to find the info in the documentation/internet (Didn't try hard enough to find the info ha.). Though, if I had the vac, it is a nice gesture for a place it can latch to :D.. Also to you guys. Thanks so much for your products, and for taking interest in us customers! And thank you for the response to my comment.

[@abcxoxo]

Bought an FX6 filter and it didn't come with a draining hose, do i need to buy it separately? and where can i buy it from?

[@SugarFreeKool-aid.TheWorstKind]

When you add the food (flakes), do you have to unplug the filter??

[@fluval]

When feeding it is a good idea to feed small amounts allowing fish to consume all the food before putting in the next portion, if fish are fed in small offers then there is no need to shut the filter down. When it comes to bottom feeders the fact that the food is on the bottom should suffice. in preventing it from entering the filter.

[@djamped]

Hi thanks for the video, I am about to purchase the FX6 for an outdoor aquarium, I would like to have the glass bottom drilled so I can have the intake and out take hidden and coming through the floor instead of coming up over the back of the tank as its not very pleaseing to the eye. Can you tell me if this unit can work that way or will the pressure of all the water create an issue with the filer ?

[@fluval]

The pressure is the same whether in either case, you would need to ensure how you have plumbed in that instance is secure. Also please visit fluvalaquatics.com to download the instruction manual which has maximum vertical hose placement specs for using this filter.

[@pucka_ak47]

if i put this in my 160 l tank then how often i have to change the water...i have only 9 very small african cichlid inside not even a year old...

[@fluval]

While a filter does help maintain better water quality the frequency of partial water changes should be approximately 20% bi monthly. While your African cichlids are young (what species are they?) the benefits of following a good regular partial water change schedule will benefit their growth rate. The FX 6 is likely unnecessary for 160L, a 306 or 406 would be the logical choice.

[@elleziehl4734]

What are the exact measurements of the fx6? I need to make sure it fits under my stand.

[@fluval]

Elle Ziehl Thank you for your post and interest in the Fluval FX6 filtration system. The dimensions are: (L x W x H): 37 x 37 x 58 cm (14.5 x 14.5 x 23 in).

Why my FX6 looks different ? Mine doesn't have the monthly indicator dials .

You have a newer generation of FX6. The indicator dials have been removed on the latest generation.

[@joeymczeus6476]

is their adjustable flow on the fx6 & fx4 models?

Hi Ryan, you can make adjustments with the included Aquastop valves, we advise not reducing flow by more than 50%.

I have both your fx4 and fx6 on my 125 filters are great media has to change. I replaced all media that came with these filter.

We used this aquarium for demonstration purposes only, it is approximately 35 gallons.

[@904fishingmusicandadventur9]

quick question... This is the first video I have seen by Fluval Aquatics.... I saw how you attached the hose to the top of the tank, but I have a plastic rim that goes all the way around.. i believe mine is an Aqueon 75 gallon... I already have a Trigger Systems 39 Sapphire hooked up to my aquarium. I want to add a canister filter and it looks like this is the industry standard.......BUT, is there another way to assemble for a tank with a lip around the top? Have you produced other videos about this product? Link? thanks for your help

[@fluval]

If by lip you are referring to an inner glass brace you can always have two holes drilled through the brace to allow passing the hosing or fittings.

Dear fluval I have a question can I run my 175 gallons just with a fx6 or I need something else? Thank u

[@fluval]

Diego Bilotta Most likely you can, however it always depends on how many and what size fish you are keeping, your feeding program and other factors as well. If you would specify the species, the number of fish you have, and what you plan to feed,, we'll be more than happy to provide some input.

I have had the fx5 for about 2 years. I have been seeing a lot of micro bubbles lately. Do you have any suggestions ?

[@fluval]

Hi, I would check to make sure you are not overloading the filter media baskets, that the media is fairly clean, and that the filter hosing is relatively straight with downward loops or bends. If your foam filtration is over a year old, replacing it can help as well. Is this a marine or freshwater aquarium?

[@mark-allanpilgrim7028]

I'm strongly considering getting an FX 6, but I am adamant i would like to continue using my brilliant BIOHOME media( which has unparalleled nitrite and nitrate removal ).Can I just ask, the way the FX6 is set up...?Does the flow through the media canisters go from the BOTTOM to the TOP before being sent back to the aquarium or is it TOP down to BOTTOM? Reason I ask is that to work 100% effectively, BIOHOME needs mechanical filtration ( waste particles etc ) before the water hits it ( the water should be particle free ).Many thanks for the help

[@fluval]

+Mark Pilgrim Hi Mark, the flow travels from the top to the bottom. The pump inlet is at the bottom of the media baskets.
