Tetra 77851 Whisper Air Pump

I have purchased few other brand air pump that claim to be silent, but never got what I wanted. This product on the other hand is worth buying. It is super silent and is powerful enough to provide adequate air flow for my 70 litre tank. Product comes in good packaging and the seller is in constant touch with updates and providing usage details till delivery. I can sleep peacefully next to this air pump and never get disturbed. This requires a maxcon voltage converter. Must buy for home users. Hardware is very sturdy and strong. This product even looks good with it's brilliant designed shape for silence.

The local pump we got from our pet store was driving our whole family insane with the noise. This has been a godsend! You can hear just the bubbles sometimes, it’s that quiet. I needed to purchase a 120 V to 240 V converter plug to use this in my home (otherwise could smell a burning smell coming from it) but it was absolutely brilliant once I got it working!

So far so good , no noise at all , caution : requires step down voltage converter recoomnded : maxcon

Very good output

very wrost air pump, noise like a diesel generator and getting over heating very fast.

product start making sound and vibration from the very 1st day

The product appears ok. But the device is for 110 volts 60 cycles USA standard. Here in Australia it is 240 volts 50 cycles.. Some one never checked..

At first when I set this up, I put the pump on top of my aquarium hood. It was really, really, noisy. I was so discouraged thinking I wouldn't be able to use it after all. Then, I started experimenting with places to sit the pump on. I put it on my kitchen counter (as my fish tank is right next to the counter), and low, and behold, so quiet I couldn't even hear it unless I put my ear almost touching the pump. Also, the pressure is pretty powerful for this unit, especially that it is for a 10 gallon, and I am using it on a 30 gallon. To tell you the truth, I wasn't expecting many bubbles. But, it does blast out lots of bubbles. Another big plus to this unit is it comes with a small valve that you can put on (by connecting the tubes to either side of it.) That valve is awesome because it lets me control the flow of bubbles. At night, I like to turn it down for the fish. So, that was a big plus for me. Also, it's bigger than I thought it would be. That's fine too. I was thinking it would be a lot smaller. It has rubber feet on it so it doesn't slip on its surface, and it controls the noise. I highly recommend this unit. But, like I mentioned find the right surface where it will be absolutely quiet before you start posting about how noisy it is.. The shipping was so fast. It was here in a day as promised. Thank you again for the great service. I would like to add some feedback about leaving product reviews. Could you please include the product name in your review. That way we are reading about the exact product we are researching. I've been reading so many reviews on Amazon products I research that are not even related to what the product is mentioned on the sale page. Thank you. UPDATE: June 2021. The part that connects the hose to the unit completely broke off (not repairable), it wasn't dropped or misused, so It only lasted 14 months.

Received with thanks

Tetra Whisper Easy to Use Air Pump for Aquariums (Non-UL) ~ 20 - 40 gallon ~ AKA Whisper 40 Upgrading from my long running Whisper 10 to a 40 as I'm adding a sponge filter to the mix. And my 10 which is still going strong will be kicked down to a 5.5 gallon tank for quarantine or fry. New one seems just like the old one just a little more powerful which is exactly what I hoped. I find these style Tetra pumps to be kind of a gold standard because in my experience they're quite reliable and long lasting, maybe not the quietest on the planet but not loud at all, and very well powered for the price, which is very reasonable. And they've been around for quite a while and sold in a lot of places so they've got consistency down. You can get a quieter pump but will pay a whole lot more for an actually long lasting one with the same power, and I find these Tetras to be reasonably quiet. Unless you're really critical or sensitive to a low hum I don't even notice from across the room. And you can find cheaper pumps, or ones in the same price range with a 2nd output or adjustable flow, but they are usually under-powered or disposable junk. These Tetras are just all around good solid basic air pumps. And I can just split or regulate my lines. I do wish they would stick to listing these as "Whisper 40" or whatever like it says on the pumps or a standard model number like "AP-40" instead of this gallon range nonsense. The original numbers were always implied gallon ratings anyway but this range thing being the main naming distinction just muddies the waters of what we're all used to. I'd say 20 - 40 gallon is a fair ballpark range for a Whisper 40 but there's enough variables that could easily throw that off that it doesn't make sense for the main naming distinction. If all you want is a single little air stone a Whisper 10 would likely be all you need up to 30 or possibly more gallons. Definitely for a 20 long which isn't that deep. And if you had a 10 gallon tank with a sponge filter or bubble wall plus some other bubble feature you would definitely benefit from going up to a Whisper 40. Implying gallons it in the model number is fine, at least we know the models, getting rid of model numbers so the pump doesn't even have a name any more, just a range of questionable accuracy is stupid in my opinion. Plus it's just a nuisance taking something that's been around long enough that tons of people know the standard numbers, not to mention it's mentioned that way all over the internet anyone new to the hobby will find, and now have to decipher what this range nonsense is. I come knowing I wanted a 40 and see 20-40, 40-60, etc, and I'm like what? I know now the max number is the one that corresponds to the old standard number but it's just stupid. The one I got says Whisper 40 on the bottom of the pump as I would expect but that's not in this listing anywhere. Why? And you could still list the suggested gallon range in the description or on the box somewhere, just put a standard non-changing number on the box and anywhere there's product selection online so we can know the model without playing games.

Se la recomiendo ampliamente, muy silenciosa
