AQQA Aquarium Air Pump,3.5W 5W Dual Outlet Oxygen Pump with 2 Air Stone,Adjustable Air Valve Quiet Bubbler Pump,Up to 160 Gallon Fish Tank (3.5w)

I absolutely love these air pumps. They’re quiet and effective. I just wish that AQQA made single output air pumps as well. You can easily make a dual output pump into a single by adding a short length of hose to one output and capping it with a flow adjuster set to closed. If you don’t do this, the pump will run loudly. You can see how I set this double pump as a single in my video (the other tank is running a single AQQA pump using both outputs). I have two of these and they’re both very quiet. Just a low hum. I have two Tetra whisper pumps, one is a 20 and the other a 10 and they are both loud in comparison. If you’re looking for a quiet pump just get one of these, even if you only need one output.

I have two of these running on my tank and they work great. Fairly quiet, especially if at slightly less than max settings. I like the dual outlets with the option of connecting both to a single filter or stone or having two filters or stones (or a filter and a stone) attached.

This is a small pump and air stones for an aquarium but I am using it for my plants water. I started using it almost immediately after receiving the product and so far so good. It's turned up fully with both included stones attached and it's really moving the water around and throwing off lots of bubbles. Seems well made and it's pretty powerful for such a tiny little pump. Great value and quiet even at full power it's not that loud at all. Works great includes 2 stones, hoses and 2 pieces to prevent water from backing up into the pump that only needs used in certain applications. Great little pump 5 stars from me!!

Works well put out a lot of air. Noise level is kind of low.

Very minimal sound' almost quiet on the lowest mode -Easy Install: Pump' Tubes' Air stone' Water backpressure stopper -Cord is a decent length -Very quality pump i must say

This is an awesome set. I am so pleased with this purchase. The air pump is very quiet ( might help that I placed a thick gym mat, cut to size and placed pump on top). Also love the dial that you control the air flow(bubbles) with: from very fine bubbles to the highest setting, which is quite powerful. In my video, I have it set at 3/4. Came in pristine condition with all accessories shown. Everything as described. Easy to set up, has a small footprint and seems quite durable. I used my own black silicone tubing, instead of the clear tubing that came with set. 5 Stars all the way!!

Filter died and needed a temp replacement, so I ordered this. While it WOULD BE quiet, it's not. Reason being, the hoses provided keep popping off of the air vents!?! I've tried using different tubing (smaller, larger), tried putting a small slice in tubing to make it slide up farther, etc. For the life of me, I just can NOT get any tubing to stay connected for more than 10 minutes before blowing/ popping off!?! Once the tubing pops off, the thing is just loud and humming/ vibrating all over the place. Oh well, this was just a temporary use item,but if it hadn't been?? ...I'd probably have had to return it I love that it has two outlet ports for airflow (if tubing stayed connected) and the included air stones. Everything needed was included I guess, but the included tubing was very thin and popped off the outlets as well and needed replacement (so i thought). Shipping was extremely quick, received in about 2 days! Maybe mine was defective, I don't know - but I wouldn't recommend...

Works well, just the frequency in my country isn't suitable for operation as it causes pump to heat up It works better with 60hz Overall it works well,and the hose are a good length

Works well, not too loud. You can adjust bubbles flow, so if you think it's too loud just close off the air valve more. Nice little pump, good value

So far is working great! Not too noisy at all a bit louder than my usb pump but provides much more airflow, so it’s an easy trade off for me. Would recommend.

Had a few glitches but over all works amazing! Still pretty new the the aquarium game (1month in) but was ecstatic to hear I can plug this into a sponge filter so now I have one air stone going and just purchased a sponge filter and everything is working well

Wish i bought this before i bought my nano silent 1w air pump. While that was actually SILENT, this is not... far from it, but it's not to say that it is loud. there definitely is a "hum" sound when you're close to it, but when you're 1 meter away, its definitely quieter. Currently this is driving a dual sponge filter and air stone without any problems... since it's 5W i expected a lot more power compared to my other other 2w air pump, but it seems to be on par which is a bit disappointing, but i will definitely keep this because my other air pump, although less wattage, was way too loud. For those who want a SILENT air pump, i've heard hygger is really quiet, but at around double the cost of this, i rather stick with this brand. Edit after using it for over a week, my breaker kept tripping. Couldn't figure it out. Turns out this kept tripping the arc fault in my circuit. My circuit is NOT overloaded. Everything else working fine until I got this. I did not minus a star for this because it may just be the luck or the draw or my sensitive Breaker....i did remove 1 star because the power draw of this 5w pump never exceeded 3 watts. I suspect their 5w is the exact same as the 3w except the sticker. My DC inverter uses about 1w idle so probably pulling just under 3w on max power. This makes sense it's not actually 5 because the output of this is actually comparable to my weaker air pump. Pretty disappointing

Great replacement. Dual outlets and variable pressure. Excellent for the price.
