hyggerSmall Quietest Aquarium Air Pump, Adjustable Oxygen Pump 2 Air Outlets Ultra Silent Powerful Aerator Pump 160GPH 5W

I honestly didn’t believe the hype until I plugged this in—this air pump is amazingly quiet. After years of dealing with a noisy pump, I can’t believe I waited this long to upgrade. The build quality is solid, and it pushes out an impressive amount of air.I’m running both a 6" air stone and a 24" bubble wall in my 150-gallon tank, and I’m only using half power! The output is more than enough, and the silence is golden. It’s been running consistently and reliably.Highly recommend!

So far it's amazing, I just put it all together and hooked it up to a sponge filter for my shrimp tank and then left the other hose as a bubbler. It is beyond quiet, no annoying vibrations that drive me crazy. The air output is strong, and very efficient. I am not disappointed in this air pump at all! I would definitely buy another one if I ever need too.

soooo quiet! Set up a new 20 gallon hex tank and bought a tetra whisperer for my sponge filter and an airstone. It couldn’t power both at the same time and was SO LOUD. This one is so quiet and i have it turned pretty low and it’s producing so much air for both the sponge and airstone

Pros:- Just like all the other reviews say, this is a quiet air pump. It's not silent but puts out a small hum that's difficult to hear, even if you adjust the output to the max. It is however the quietest air pump I have ever come across.- It puts out a generous amount of air, enough to power sponge filters in my 60g tank and 5g shrimp tank simultaneously. My aquatic pets seem to appreciate the extra airflow and water movement.- It doesn't seem to generate much if any heat. Some other air pumps I've seen have a noticeably warm sensation on their housing, probably from the vibration of the diaphragm inside. This pump says it's magnetic, there's no vibration and you can barely tell it's on.- The build quality seems solid, as of this writing I've had it on for three weeks, 24 hours a day, no issues so far.Cons- It's a little larger than other air pumps but that's a small trade off based on what it does.- A little expensive but you get what you pay for.

Very quiet, moderately powerful air pump. Actual flow was 720 L/hr with no airstone 30cm deep and falls to 540 L/hr max with the airstone. I couldn't get any more than 7.0 watts of draw. The flow vs power is pretty linear which is good for efficiency. It is big and ugly in my opinion but it's going to sit in a cabinet and has a flat top which is helpful if you are limited on space and need to stack something on top.

Works quietly and strong

Update 2: I pulled it a part for a third time. I bought a screw extractor set and I was able to get the stripped screw removed and the diaphragm replaced. I put it all back together and now it is running beautifully and silent. If it had ran this way from the unbox this would be an easy 5 star review. I am $65.00 in on this pump now and it is finally working well after much headache and extra money spent.Update: I received replacement diaphragms that I had to buy, I was able to get one replaced but the screw on the second one almost instantly stripped. I now have a horribly unbalanced single channel air pump that sounds like shaking marbles inside of a cup when it runs at full power. Cool. Still disappointed.I unboxed this after receiving it to get the cardboard recycled asap. I didn't get it installed until a week later. I immediately noticed that one of the ports had 0 air flow and the second was incredibly poor. Unfortunately without the box I doubt I could return it. I took it apart and noticed that both diaphragms were split open. I'm having to buy replacement parts before it's even seen any use. BEWARE that this could happen to you. Keep your box! I have a cheap tetra dual port pump from Walmart that's been running non stop since 2018 and still has amazing output. This has me regretting not getting another one of those. My hygger is now in pieces until I can get replacement parts.

The media could not be loaded. Pros:-Powerful-dual air outlets-low noise-flow controlCons:-high pitch him at high flow-size could be an issue for someSummary:I've gone through many pumps on my search for a reasonably priced, powerful pump and upon first impression this one is indeed impressive.The packaging was very Nice- surrounding the product with custom foam for added protection. Bonus- you can use the top insert as a mat for the pump to help dampen noise if you find the need!The size was a bit larger than I expected but I have a good size shelf and it can still be tucked away with my setup. First the noise I'm pleased to say is indeed quiet. Yes you'll still hear a hum- but unlike other pumps I actually don't need to place it on padding for it to dampen the noise!Next is flow- the low noise had me wondering if flow would be an issue (as it tends to be with many pumps I've tried) but this one is able to handle my 50 gallon tank no problem. I even was able to use the 2nd port which is something I've never been able to do. The flow control works well--however the higher you turn the knob a high pitch tone begins to emit. So I keep it in the middle where it remains quiet.In short, this pump is worth the buy. I'll update as time goes by- sometimes pumps start strong but peter out within a year. Hopefully with this one my search is over!
