Cobalt Aquatics Phantom Ultrasonic Silent Aquarium Air Pump Review. The Most Quiet Air Pump?

– Hey, everyone. This is
Cory from Aquarium Co-Op and today, we’re gonna be reviewing the Cobalt Phantom
Ultrasonic Silent Air Pump. So we’re gonna be using
things like this flow meter to test how much air
actually is putting out. We’re gonna use this dB meter to test how quiet it actually is and then I’ll just give
you my overall results and things like that
so we’re gonna go ahead and get started. See the first thing I do like is it comes in a cardboard box, whereas, a similar pump to
this called the aPump by Collar comes in a metal box and in my review, I don’t like that because I think it’s killing the
environment by using metals. So I do prefer the box compared to some of the competitors. That’s a good thing. Let’s go ahead and open it up. Looks very similar to Collar air pump, packaged very similar, even comes with the same airline tubing and air stone here. I’m kinda glad to see
it hasn’t deviated much because that probably means
it’s a very high-quality pump, which is good and backed by
Cobalt with the guarantee. What we’re gonna do, we’re gonna grab the airline tubing, and we’re gonna go ahead
and connect it to one, or not one side, but we’re
gonna connect to the pump here, and then let’s see how long the cord is. So it comes with the same 3-foot long cord that the Collar air pump is and without knowing any better, I might say this is the exact same pump because there is no branding
on the actual pump itself and it’s running very similar but… We’re going to connect
it to this flow meter and I just gotta put
it on the bottom here. This shows me that we’re
getting a little bit less than half a liter per minute of flow, which I can show you there, if I get the numbers there, which happens to be identical
to a Collar air pump. All right. Low flow but this is kind
of meant for a nano tank even though they do claim it will pump 31.5 inches deep, which I’ve seen in other review videos that it will do that
and we’re gonna test it back here on this aquarium,
which is 25 inches deep so we’ll know at least goes 25 here. So you know, not a ton of output. That being said, it is
running very, very quiet. It has a suction cup on the bottom so you can suction cup
to the side of your tank so it’s unlikely to rattle. That being said, just
like in my Collar air pump or aPump review, once
the section cup does go, it does not appear to be replacable so take that for a grain of salt, or with a grain of salt I should say. So next, we’re going to attach
the air stone it comes with for the sake of the test and we’re going to monitor how
quiet it is right next to it. It is between eight and nine decibels, which is very quiet. Yep and when I talk, it obviously inflates
and things like that, but it is between eight and nine dB and that’s here with this
free app that I’m using that is recording my voice. So you can see it when I stop talking, it’ll jump right back down. This is me holding it an
inch away from the air pump so it is… I don’t think they can
make one quieter than this. That’s the metric is 8 dB. I’m not sure you can have a device that’s on that will be quieter than this and actually produce air. So believe me that it is very quiet, much quieter than the
other air pumps I reviewed, which I could put a link here to that, where it’s like the EHEIM,
The Whisperer, Aquatop. All those pumps right
here will be in that video and you can see that at 8 dB, it is way, way, way more quiet than those. The next thing we gotta test is will it actually pump down 25 inches? The problem I run into is when you try to pump something down 25 inches, the hose gets filled with air and this non-weight air
stone wants to float so I always test with
the Never Clog Air Stone, which is weighted and will
help us with this test. I sell these on my website. According to, I have to import them into the country but they’re great because
they don’t put back pressure on the air pump and they allow good flow. Next, we’ll cut to it
actually running on the tank ’cause I can’t do it from here. So as you can see behind me, it will pump all the
way down to this tank. It’s not quite at the bottom there just because there’s so
much oxygen in this tubing. That being said, I’ve
got it stuck to the front of my tank here, which typically you would
do that either on the side or preferably the best
way you could mount that would be on the top. If you mount it on your top glass, that way you don’t need a check valve and it can’t siphon any water out if the power is to go out
so that’s a good thing. So I would say overall the
Phantom Air Pump by Cobalt is a great air pump. I would say it’s very
similar, if not the same, as a Collar air pump, or aPump, except you get the 3-year warranty and you’re much more likely
to find this in a store. I’m going to bring this
into my retail store and so there’s no reason to
buy one that is unbranded and not get a 3-year warranty. They’re gonna be very price comparative. I think the aPump that I
bought for my review was $27 and I believe this one retails at somewhere between $27 and $29 and yet, you get a 3-year warranty, whereas, the other one
there’s no warranty. I see no reason not to buy this pump, better packaging, seems
to be the same exact pump, great for nano tanks. It will also pump very deep. You don’t need a lot of
oxygen to actually add oxygen. It does pump deep, which most
ones couldn’t even do that. It would’ve given out
with the back pressure so it is a pump designed
to pump low amounts of air very deeply and silently. That you need to know, if
that’s what you’re looking for, this pump is unbeatable. If you’ve got a small
nano tank on your desk, in your office, in a
bedroom, something like that, this is what you need. If you need to pump air down
to the bottom of a barrel ’cause you’re mixing up salt water or need to oxygenate water before you change water in the fish room, this pump’s gonna do it too, where your average pump you’re gonna have to use a way big pump or you’re gonna have to
use some other method because this little pump is
about the only thing I found that will do it and do it efficiently. I give this pump a thumb’s up. I encourage you guys to go buy it. I’m gonna put a link down
below in the description and right here to actually
buy this pump on Amazon so if you don’t have a local store, which I always say support
your local store first, but if you don’t have one,
go ahead and support us by buying it at our Amazon link. We’ll make fifty cents and it’ll help pay for the next review and more gadgets so that we can actually
monitor this stuff for you. Thanks for watching and
if you’re interested in getting this exact air pump, go to and join team Aquarium Co-Op, which is a newsletter we put out, only for our YouTube subscribers. Basically, every time we get
a product like this to review, we will give it away. And so what we do is we pick
one of those email addresses, we shoot you an email and go, “What’s your physical address?” We’re gonna send you this
air pump or this filter or this fish food or whatever
it is that we’re reviewing. Thanks for watching. If you have any questions, go
ahead and put them down below or any comments about how to do this test better or improve it. If you haven’t subscribed already, go ahead and subscribe ’cause
you can see other videos like this and other content we do, fish room tours, store tours,
DIY projects, all that. Until next time, we’ll
see you in the next video.

  • I can see this video as part of the "air pump reviews" playlist, but it doesn't show in the regular video list.

  • where do you get the flow meter?

  • Wtf 25$ might as well spend a couple more dollars and get an Alita pump from jhemco and pump a whole room full of air

  • Nice product review, Cory. Next time you do a review on an air pump, can you show us the "Never Clog Air Stone" bubble spread? Do the bubbles just come out the end of the air stone (like it appears in this video) or does it function like a regular disk or block stone? Thanks!

  • do you think it would run a small sponge filter ,moving bed filter or MHF ?

  • Great review, Cory! Well done!

  • Another great Video!

  • Nice video, enjoying your videos, just subscribed this morning 🙂

  • would that be good for diy algae scrubber

  • Great video, nice review. Also, I signed up for your newsletter.

  • oh no way thats pretty cool that you picked up a flow meter. now that you picked up one i am curious to which of the pumps from your other video pushes more air. but that sure is a silent pump. i hear lots of great reviews on cobalt products.

  • Great video! The aPump however does offer a dual output model and also I have to add that the dual output model comes in a cardboard box not the metal one. I think only the single output model of the aPump comes in the metal box. You should do a Video on both models the aPump and the Cobalt!

  • What's supposed to be the use of a metal box?  Don't you have to take it out of the box to use it?  The only pump I ever saw in a metal box was the old Silent Giant pump. That was a powerful vibrator pump that was packed in a tin can filled with sand.  The sand absorbed the vibrations from the pump and made it run quieter.  This just sounds like an advertising gimmick and a waste of energy.  The box wouldn't help the pump run  any better or quieter, would it?  A sheet of bubble wrap and a cardboard box would protect the pump in shipment just as well, and be a lot cheaper to make..

  • w i c k e d update

  • Nice info, could you add a wattage meter to the testing? I doubt a small air pump would make a difference but there may be a breaking point that a large system makes more sense verses many smaller pumps

  • That's amazing . I should use that on a future Nano tank I'm setting up

  • Your video is the best review out of everyone else that did it. More persuasive and indepth.

  • Wouldn't surprise me at all if Colbalt is just rebranding the Collar apumps. I know they do that with the Ziss egg tumblers.

  • Spot on with the review homeboy. Love the science! Church!

  • I have mostly nano tanks or shrimp in 40G breeders. I think this pump would work nicely for me. I'm always looking for a quiet air pump.

  • the average room is 35 db so highly doubt its that quiet but agree very quiet

  • Do you think this could pump two lines with an air stone on each? I use one small (loud) pump split between two 1 gallon tanks.

  • Can I run a sponge filter with it?

  • Will it work well running multiple airstones ornaments and or in a gang valve

  • I searched you tube for a video on never clog air stone you sell so I posted a video to share the knowledge! Hope it helps sales!

  • To anyone out there. If you had 10 – 5 gal. tanks, is there a pump that could handle all 10 at once? Any recommendations?

  • I think the fact that i didnt even know you plugged it in, speaks measures! Thanks, Cory.

  • Hi, Cobalt Aquatics Phantom VS aPump noise. What is the best with lowest noise?

  • the output is a bit low, do you think it'd be suitable for an hmf filter on a 20 long shrimp/danio tank?

  • not a usable pump in my eyes … next to useless

  • pricey piece o crap ….. you prob pumping em coz you sell em dude

  • I got one to power a sponge filter in a 10 gallon(if that) aquarium.
    i thought i had done enough research but right after i had ordered it i suddenly find all these reviews saying its under powered for that purpose.
    reading your comments here on other people comment is giving me some hope it will be fine and i can enjoy a nice silent aquarium.
    since it is going to be less then a meter from where i sleep

    Thank you

  • they all start quiet, but how loud does it get after 3months

  • Would you recommend this to run a bubbler ornament or air stone in a 10gallon tank? It's in my daughters room so I like the fact that it's soooo quiet. Could this run one of the sponge filters you recommend for a 10 gallon? Any other air pump recommendations? Thanks for the great video!!

  • I have the tetra whisper AP150 and have it hooked up to a 3 foot bubble wand and also a 14 inch bubble wand also it's very quiet

  • on previous reviews yor talkin db were 65-75 now its 35 nicee lvl up

  • On eBay it's $49 with free shipping

  • Like it great idea, iv just purchased the EHEIM 200 from my local aquarium on sale for £9.99 uk

  • I see people usually using this for air stones but could it work on a small sponge filter

  • When you say its better to put it on the top of the tank, can it be put underneath the lid or it needs to be under water? And ould it work for more oxigen and air flow in my 10 gallon tank withe the aquaclear filter. And compared to the aquatop breza you sell which one is less noisy and which you prefer? In the link you posted its really expensive like $325 i gues it will stay there bummer

  • I just followed your Amazon link. I think there's a mistake, its selling for $329.00 there. I would like to purchase one, but not even near that price. I do enjoy your channel, its very informative. So much so, that I share it with the fish department employee's at Petco and Petsmart.

  • The whole support your LFS is a great aspect, I did it for years and still believe in support local businesses. I do have a harder and harder time doing it as the years collect though. Today I was browsing my LFS's new stock and checked out a tetra 100 whisper and they had 35 bucks on it. Amazon has it for 16.99. The next 3 or 4 items were the same way. Anyone else struggling with this moral dilemma?

  • Amazon says this pump is no longer for sale, is there a new version that is just as quiet?

  • I don't think this is made anymore at least I can't find it. tells me this pump wasn't good quality. also I bought some cobalt food and my crystal clear aquarium got cloudy.
