Nice to see a very easy, non rushed and straightforward demonstration, without making any assumptions about the level of knowledge of those watching.

I got this vacuum yesterday and hooked it up per the video instructions. It worked well. The vacuum is more powerful than a siphon vac of which I have a couple. I tried to make my own power vac using a pump but my sand substrate would foul it almost immediately. I have a huge plec that is a crap factory and the siphon tubes will not pick up the heavier waste. This vac gets it no problem. The nice thing is that I don't have to worry about buckets and running out of time before they fill. You can vacuum all day with this system. I got the super fine sock and it did not let any sand into my fx6. This system has a fair amount of parts but in my opinion worth the small extra hassle setting it up since it does a much better job. I still do water changes but I see myself vacuuming every few days and weekly water changes on a day that I don't vacuum. We will see how it works.

Got my vac yesterday.....So easy to use and setup.....Sat there for bout an half hour getting every nook n cranny of my gravel.....Best thing ever....Thanks Fluval!!!!!!!!

I've been using a python for years and if you just want to wash the gravel and not perform a water change this is a simple and easy tool to use. The FX6's Motor is powerful and washes the gravel effectively even with the extension tube attached. For a water change I will still use the Python and wash the gravel at the same time but for intermittently clean up this product works perfectly. The key is not to let your tank waste build up and this product encourages you to frequently wash your gravel effectively with its quick attachment and minimal mess. I purchased the FX6 on its own but this is a great attachment that utilizes the FX6's drain feature and powerful motor..........nice job Fluval. P.s. For those who are complaining about it not being free....get real, all you have to pay for is shipping.

I just bought the fx6 for my 250 gallon absolutely love it!! Now I definitely need this.

got one free with my fx6. can't wait to give it a try. thanks fluval

very good IKEA-style video! No words but everything explained

I'm from UK, i've had mine a few weeks now, started using mine yesterday, i don't like using the end that goes into the gravel i just tilt the bottom tube a little and the gravel sucks up the tube and spins up and down until you lift the tube, what i do is move gravel from one end of the tank (about 12 Inches) so it leaves a space, when rubbish has settled clean the space you have made then put the tube into the gravel, tilt the tube a little and you will see the gravel going up and down, then after a few seconds drag the tube across the floor of the tank where you have made a space, lift the tube a few inches, tilt the tube about 45 degrees and the gravel will slide out of the tube, then repeat until all gravel cleaned, JOB DONE. i must also add, watch how much gravel you put into tube-s, if you put too much in, it goes up to the gravel stop and blocks water/gravel going up the pipe, if it does just move the lever at the top of the tubes and gravel will slide down tube, turn lever back. i'm really impressed with this gravel cleaner, the hose is a little awkward when moving cleaning tube-s around tank, could do with a flexi- hose, also the pulling power of the gravel cleaner through my FX6 is very powerful that's why i said be careful how much gravel you put in the tubes. I hope Fluval offer me a job after this honest review, LOL.

Great product works amazingly well, wish I had brought it months ago, big TICK Fluval

Great tool hope when i buy my fx6 today it comes with Also nice to see 70’s Porn music is still alive in 2019🤪

Awesome...Cant wait til i get mine.Can take my time sucking all the waste up in my tank without having to worry about my buckets over filling....

People don't quite seem to understand the idea of this. First you do the gravel cleaning with this. Then you can put the hose into a bucket, turn the filter off, and open the utility valve. The water will then siphon into the bucket. Since you have a standard quick connector at the end you can of course also extend the hose to a drain if you want to, as long as the drain is lower than the lowest level you wish to drop your tank to. This is way it will completely eliminate the need to carry buckets, at least for the emptying and cleaning.

Nice idea! Looking forward to seeing this reviewed by people on the hobby...

Fancy this for my fx4

I'm hiring your DJ for my next party. Fluval is too cool for school!

I NEED this to be released in the UK NOW!!! :)

I like this product so much I think you should have a can the size of my fx4 with a giant fine pad so I can have it running all the time I find myself taking my time when cleaning the tank now

A couple of observations: 1) The effort to use this vacuum system is a lot more effort than simply vacuuming off the dirt, sludge and detritus into a drain. 2) Good aquarium hygiene requires the sludge, dirt and detritus from gravel cleaning to be removed from the aquarium system. Granted some is captured in the filter bag, but a lot of this waste goes back into the FX filter which appears to be connected to, and circulate water back to the aquarium. Looks like a fancy "toy" that will not help the aquarium inhabitants.

Nice concepts, but by the time u hook that up to everything I would’ve been done. I like to gravel clean and drain the water through the syphon as I clean the gravel.

well I'll be damnded.. that's pretty awesome. good job fluval.. no wonder i, as well as millions of others love your products. really want one of these filters. but pretty sure it'd be overkill on a 55g lol

Would have liked to hear the steps being explained throughout the video.

I love mine works perfect does the job better then other vacumms

I have the fx6 and was wondering if this is also for saltwater aquariums with live sand substrate?

Just bought this and tried it today --what a mess it made of my water and hardly any suction...and yes I did follow all the instructions. I had my husband then do it and double check we had done it right. Siphon and bucket worked better. Can I get my money back???

thanks for the great video!

I have the most pooping gigantic pleco. This is most definitely easier than raking all the gravel out and rinsing it

purchased mine a few days ago, great addition to my Fluval canister. I have a reef tank with a sand bed, Should I throw out the sand that's collected in the bag.

A high tech and I assume high dollar solution for a simple task. Fish keeping is fun and has its rewards. Don’t let your hobby become a money pit. Fluval has wonderful products but sometimes it’s a bit much. Just my opinion.

looks like it does a good job but also looks like a lot of messing around

I like the content of the video as I have a FX6 but what's with the very loud background music.

I am about to order this ❤

Where can i order this from. Your website did not have it. Thank you

Do we really need this attachment? can't we just connect a python syphon and just let the waste to into the canister filter?

Who's the musician on this track. it's awesome

I change about 50 gallons of water weekly on my 75 gallon discus tank so I always have fresh water. However, my water pressure is horrible so I can never properly clean the substrate. This looks like it would fit the bill for me even though there is alot going on in this contraption. Can't find anywhere to buy it in the states though.

Carnt wait to pick up one of these! Well done fluval...The bonus with this gravel vac is if your gravel gets bad you can remove ALL the waste and still have total control of the amount of water you take from the tank. To big a water change for certain fish is no good. This is a very good idea. Fluval is there any news when this will be sold on its own. I want asap plz.👍😎

Hello. I can’t understand it myself and I can’t find information anywhere about the suction cups that come with the filter; these are the suction cups that are in the bag with hose clamps. Do you know what these suction cups are for and where to install them?

I was going to order this as part of the promo with the purchase of the FX6, however, after watching this video, I realize it will not work for me since I decided to go with sand in my 125G aquarium.

Interesting concept... but I'd rather dump all that gravel gunk out the door and off the deck with a hose instead of trying to filter it out with a canister filter. I was amazed you could do that though.

I'm pretty sure I just cleaned my 55 gal tank in less time then you spent setting up this contraption.

I was under the assumption you could use this with the filter while the filter was running normally (doing its filtering job), but looks like the person with turning the inlet valve on and off? Do you need to disconnect the filter from the tank to use the vac??

I'd very much like to know if there is a similar product for the 307 Cannister filter, I'd very much love to ditch the weak little electric thing I bought, as it doesn't seem to do well for 5 goldfish in a 55 gallon tank.... Oddly.

Does the filter need to be powered on to use the gravel vac

👍👍👍👍

Okay guys anyone needing an open and honest assessment about this vac. It works as the video describes but after vacuuming and turning the valves of the filter back on, it kicks back suet and foul water back into the water literally everytime. Totally defeats the object. Very frustrating. I have used the vac 4 times and each time follow this video step by step. Shame really because it's a great bit of kit as is the FX6 filter. Anyone with similar issues? I will not be using the vac again. The reason this happens is because the sock in the collection canister is designed to collect waste and fine pieces (and does a very good job at doing so) But obviously the suet and cloudy muck isn't going to be collected by the sock, so your canister fills up with this cloudy disturbed muck only to be released as a toxic bath straight back into your tank when you switch the valves back to the on position. Maybe lots of fine polishing floss would help catch some of it but either way it's inevitable you will mess your tank up with this. Please feel free to correct or advise me. The FX6 is the best filter on the market but the vac would only work properly if the water you were siphoning leaves the tank permanently :)

Is it my imagination or does it look like you open the drain valve, and close the intake? Does the drain suck water through it when the intake side is closed? Seems something that could produce a mess and shorten life of the motor if I didn't see that correctly?

The intake tube looks like it was pre-primed as there is obviously water in the gravel vac prior to turning on the gravel vac valve. How do you prime it?

Looks real nice when cleaning a tank that was set up for this vid. Try that again on a filter that is 3 months in. I guarantee the water won’t be that clear. I connected the hose and as soon as it sucked some air in, the outlet blew a huge brown cloud. Is there a fix for that or will I have to put a filter sock on the outlet too.

You need to make hose adapters so we can use the UVC with the FX6

I tried it with sand substrate and it got clogged.

Is there a way to hook to the FX6 and clean gravel while also siphoning some water off for the water change?

Hello, I've recently acquired the fx gravel vac by Fluval. Could you please tell me if the filter should be running (power on) while doing the vacuuming? Thanks in advance.

Is it normal for the fx to drop the level in your tank after you’ve used it to refill or used the fx gravel vac?

it's more work if you don't have the extra hook-up but you can do the same thing with your current canister filter if you just simply disconnect it the input hose an connect your gravel vac an not pay that money ijs

Is this still something we can buy? Can't seem to find it anywhere online?

Does Fluval make a replaceable outlet tube with a single nozzle? If not, can anyone prove a DIY to replace it with a single outlet nozzle? I don't like the double nozzle head on the output hose. Thanks...

What size is the hose I can't find the answer anywhere

I am thinking about buy your fx4 for my 40gallon breeders I just bought. I am using 206 and aqua clear 110 on all my fish tanks. But now I have a total of 8 tanks which is a lot when it comes to doing water changes and cleaning my canisters and hobs. Dont get me wrong i love my fish, but i rather spend more time enjoying my fish than cleaning so many fliters. how long is the hose? can you add a 25ft hose to the area to add water from the sink? Or do I have a hose from the sink going into a bucket and the hose from the fx in there, to take the water out? I hate using the python because of the wasted water.

How to make gravel vac 10 times more complex!

I just got the FX4 and I'm looking around for replacement parts just because I like to have them on hand. I cant find a replacement IMPELLER nor can I find this Vacuum. Where do I get them. They are not even on the Fluval Site.

I got the fx6 for my 20 gallon aquarium, big mistake

I got one for cost of shipping with new FX6. Sucks it is missing tubes to vac gravel. I waist of money without all parts.

Looks good .. its a shame after all that tech you have to rinse out the filter sock with your fingers in a sink ... i see disposable filterbags in the future ... like coffee filter bags etc ... can i get a Fluval t shirt for my idea ? 🐠

Still unclear to me whether or not the pump is running and then you close the inlet and open the syphon valve or you get it all set up and then turn it on. Welp I guess I’m gonna learn here. Got an extra towel handy

Do I leave my fx4 running when I vacuum or unplug it ? I don’t see anything about that. Thank you

hows this better then a cheap 20$ python kit that does the same thing? plus those tubes look small like it would take 2 hours to gravel vac a 180 gallon

Bit extreme isn't it?

Has there been any leaking issues with this?seems like if there was a problem it will end very badly.

Each to his own. Far too much effort and trouble for me. Regular "gravity" pump siphon is all I need. Simple and clean. No moving parts, etc. Nice try though.

Awesome idea, but no way I would pay more than$30

I would just buy a cheap canister filter and attach a gravel tube to the end. You could pay about thirty dollars all together for a great unit. Instead of hundreds.

What’s the name of the song???

Hi Fluval, I recently bought the Fluvial FX4 and it came with a coupon for the gravel vac. The catch is it recently expired a few months ago. We bought it at the local Pet Smart. Is there anyway we can still redeem the gravel vac?

How often does the sock have to be replaced.?

how do i get mine i just bought the fx4 and it says i get it free but i don't know how to do it

Please show this system cleaning up fine play sand in a tank...the sand will simply get sucked up into the catch bag and fill it up in seconds.

the FX6 is a great cannister filter, mine has been running for several months perfectly..but honestly this 'feature' seems gimmicky. There is no alternative to water changes for your aquarium - filtering water through a sock does not change that fact. I have a $5 hose connected to my $10 gravel cleaner which i siphon onto my lawn - i wouldnt change that process if Fluval offered me this system for free.

Although the "doing" video is somewhat easy enough to follow along, I think it would be of great help to actually (verbally) explain the set up/break down assembly process. Assuming is never a good thing!!

please help was size is the tubing

Can I vacuum sand with this?

good idea but not much use for a planted bed, not really anything you can use for a planted bed

Wow! Is that simple or what? I tink "or what".

Damn...the ole hose and bucket seems easier and faster.....JMO....lol

can you use this peice of kit with sand? with my manual one i have to hover over the top of the sand

Is this available in Canada yet? I'm planning on buying an FX6 soon and would really love this handy tool.

Will this work on a 406 canister filter ?

Fluval aquatic I just bought the fx6 but it did not come with the offer for the gravel vac is there any way I can get the offer

Very confusing... I agree with Adam regarding the motor.... Just use a python for water changes and gravel cleaning. Leave your filter alone.

Now do you make one for sand?

I finished GV 5 mins ago

Who doesnt do their gravel vacs as a water change?

Very coool!!

OK, I finally got my vac, hooked it up to my FX4 per the instructions and was very disappointed in the suction. Did not vac the gravel good at all and had very poor flow. My Cobalt vac is much better.

this is a good idea but the part that Fluval ether does or dose'nt relies is that. yes this is a canister filter that stays on the tank with an external vac system(cool idea). but after you vac that gravel it stays inside the filter( and they have a prefilter I saw that it was just a mesh net needs to be a small micron filter sock to be effective) and you then need to open it up and clean it. otherwise its brakes down in the filter releasing the same nutrients into the tank thus doing nearly nothing to begin with. also understand I'm talking from a saltwater perspective, and this seems to be ok for freshwater. but nearly useless for Marine

Nice concept but looks like a pain in the ass, Excuse the french ole school still the best way! Plus i like to refill with fresh water!

What about with a sand substrate ?

Apologize for being off topic, name or artist to the background beat?

Where can I find one. No body has in stock.

I have it. Don't like it. Its a PIA to purge the air from all the pieces and hoses. it is slow, and the solid waste is sludge when you clean the sock, making me think most of is goes back into the tank.

Will this work with sand?
