10-120 gallon aquarium air pump

This is actually silent. The top fin ones I usually use always have a humming sound but this one is silent and works great

At one point in my life, I had 8 aquariums in my apartment—nuts about the hobby. I cut down quite a bit because my new obsession is houseplants; I have 3 now in my living room. When my friend offered me a free axolotl baby, I couldn’t resist. The main reason I haven’t allowed plants and fish/other animals to take over my bedroom is because that is my quiet and dark cave for when I sleep (I work at home nights, and so with a chronic disease, I have to sleep a lot during the day). Well, axolotls are great because they require no heater or light (they live in cold mountain streams that are murky), but they do need filtration and good oxygenation. I have gone through a lot of air pumps in my life that eventually got problems with the rubber mufflers and then the vibration could drive you mad. This one has been great. We barely hear the motor at all, only the bubbles, as in the video. Somebody in another review complaint that it wasn’t even enough to power the devices for a 20 gallon tank, and I don’t understand that because I have a 20 gallon tank (a high one, too) and both a bubbler and a sponge filter. I love the adjustment knob, but I have the knob turned all the way to the lowest setting and it’s powerful enough for both. Maybe that person is using an air bubble wand that is too long or has a clog? At any rate, it has not been my experience at all and I love this. I can compare it to maybe 20 pumps that I have gone through in the past. It has been quieter than all of them so far, although I cannot speak to longevity… I have only been cycling the tank for two weeks so far. I’m definitely a fan now and I’m thinking of buying a second one.

ABSOLUTELY LOVE BOX TECH! I’m so serious, I have six tanks, and have purchased a Box Tech air pump and heater for all. I’m obsessed with the amazing airflow, the bubbles from all my bubble strips, air stones, and air pump powered filters look amazing. It’s super powerful and SILENT. It’s very sleek and pretty. It makes me happy that it’s boxy and clean looking. It elevates all my tanks, and I wouldn’t recommend any other air pump. I’ve bought this multiple times for all of my tanks and I’ll keep buying more so long as my tank numbers increase.

Best air pump ever, strong ultra quiet performance. You'll hardly even know it's running.

The only sound you can really hear is the bubbling of the sponge filter. I’m giving it 4 stars until it’s been running for 6 months. So far, it was wellllll worth the money to not hear that annoying hum that most pumps produce.

Have had this pump for close to a year now. I run two airstones and keep it on max output. That being said I've had ZERO issues and this thing is very quiet for the amount of bubbles it produces.

I placed the air pump inside my aquarium stand cabinet in top of the styrofoam packing it shipped in. On full flow, you CANNOT hear it outside the cabinet! It drives my two air stones with incredible air flow. BYW, the air flow is adjustable if you want less output.

This unit worked for a month and died. Of course conveniently it died after the return date had expired. Don't buy.

Bought this for my larger community tank. I run it from inside the cupboard of my aquarium stand and it is very quiet. It powers two large air stones without issue and hasn’t quit yet!

Just set it up today, so don't know about longevity. However, I wish I had bought it sooner. It's sooo much quieter than my previous air pump even on maximum (video). It has two outlets, so it's noisy if you only use one. I attached another "dummy" tube, and again, it's sooo quiet. It would be nice if it was smaller though, as 3"x6"x3" is pretty big.

Better than other reputable brand. Effective and no noise... Simply amazing

Flows well and is quiet.

It is quiet! But i had hoped that it would have more output. I have two small 10gal tanks and it's just enough on maximum to run two sponge filters.
