boxtechUpgrade Aquarium Air Pump, Ultra-Quiet Fish Tank Oxygen Pump with Adjustable Airflow, Powerful Air Pump with 2 Outlets to Pump Rich and Fine Air Bubbles

This air pump is amazing, such a great value for the money and outperforms every pump I've had in the past. I always thought the Whisper pumps are great but this one is far superior. They look nice, performance fantastic, pushes out bubbles in my air stone that my previous pump couldn't handle, and to top it all off... Super quiet product! The size is great for the amount of air it pushes out. I wish I looked into this a while ago! The intensity dial is a nice touch and very easy to use. I found I don't even need to put it on full power to work well.

I bought 2 of these air pumps. One for my 37 bow aquarium and one for my 20 long . I am amazed how quiet it is. It’s rather large and it puts out nice air flow. It’s just the right amount. It’s the best one on the market it’s well worth the money. If u need a double air pump buy this one. U won’t regret it.

This pump is very quiet and compact. I had some extra air line tubing and stone diffusers so I only ordered the pump. If you need the whole setup make sure to order a bundle or order your tubing and diffuser from somewhere else. The output is adjustable, but I don't think the change is that much. But for my purposes it works perfectly. I especially like that it has two outputs so I don't have to split any lines.

The pump was much larger than I thought. I should have read the description more. The air pump is quiet and powerful. The soft foot is one of reasons this pump is quiet, so as soon as something touches the air pump, it starts to rattle whatever it is touching. It should work great for most of fish tanks, but for me (10-gal), this was too big and took too much space. I boxed it up in case I need it for future.

Bought 1 a week ago for our 40gal and when I seen how well the 1st 1 worked, I got another for our 50gallon. The picture is a AquariumCo-op 2port for size reference. These work really well and are almost silent... Minimal Humming. Just a ton of bubbling from the tanks. 👍

Update:The problem wasn't the pump. It was the silicone tube. It expands and contracts causing a change in the outlet. After 24hrs in the tank, it contracted. If you stretch the tube, it bubbles like crazy. This is seriously the quietest pump out there. I can't tell it's there. Absolutely incredible! Awesome product!The first day I was blown away. I have it attached to a silicone hose with dozens of pinholes I poked into it, making a bubble wall. The first day It was fierce. The bubbles were raging out of that tube. It was a glorious spectacle. And this thing is whisper quiet. I keep seeing the Tetra Whisper being touted as the quietest in various web reviews. This thing makes that one sound like a freight train. I hear the bubbles coming out of the tube and popping on the surface, but I don't hear the pump. Incredible.Then I woke up on day 2. The bubbles were at about half what they were the previous day. They don't even make it all the way down to the end of the tubing anymore. There are gaps in the bubble wall. Now, there's supposed to be "cotton" inside somewhere that needs cleaned, but I can't find it. That little plastic circle pops out and theres some kind of synthetic felt disc in there. Is that the cotton? Who knows? They don't explain anything other than it's there and needs cleaned. Now, I did notice fibers from the disc on the white plug. Perhaps that's what happened. The fibers got sucked up? But covering that hole with my hand did nothing to the bubbles. Didn't affect the operation at all. When you remove the plug, it gets louder. But that's what it's there for.I don't know. Maybe I got a dud. I posted a question on this page, but it's gone now.

The Pump itself is quite powerful. One side is barely working though, so that sucks. It's so quiet, though, you really only hear the actual bubbles. I had to use a bubble adjuster on the tubing, as well, in order to slow the flow of bubbles so my tank was calmer on the side that is working right.DO NOT BUY the bubble stone kit though.* the stones themselves seem to work well, but....1. The bubble adjusters they sent are junk..immediately broke when trying to turn them. 2. It did NOT come with stop flow pieces for the tubes to keep water from backing up into the motor. They are a NECESSITY so I can't fathom why they were not included. Thank God I bought them right away from amazon. The motor would have been ruined because the tubing they sent me keeps coming off of the bubble stones and the pump itself.-Today, I left my house for two hours and came back to 1/3 of my 37 gallon tank emptied onto my floor and leaking into my basement! Thankfully I wasn't gone half the day or more...I would have lost my fish! The tubing had come off of the pump, AGAIN, and was siphoning the water out of my tank!*****The kit is worthless and almost ruined my whole aquarium plus property damage.To summarize:> The pump is powerful and quiet> DO NOT BUY the bubble stone kit with it.

I can’t here the pump running and it’s in my bedroom

The media could not be loaded. 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.

The media could not be loaded. Best air pump I have ever used. Silent and very powerful and it looks very nice. Easy to adjust the air flow.

I really like good products. This is one of them. Its worth the extra cost!

Runs quiet and powerful

Great
