FEDOUR 4W/5W/8W Aquarium Corded Electric Air Pump, 96GPH/160GPH/256GPH Dual Outlet & 4-Outlet Oxygen Pump, Ultra Quiet Aquarium Bubbler for Fish and Turtle Tanks up to 300 Gallons

So I had a different 4 port air pump for my 125 gallon and it worked well, loud, but it worked. Then I needed one for my 55 gallon and saw this. I figured I'd try it because I knew the other one you could hear 2 rooms away. This one works better and is very quiet! My filters are louder than this air pump! I actually sent my other one back and bought a second one and still can't hear them both over the filters and the tanks are in the same room about 15 feet apart. If you need a 4 port air pump, stop looking and put this one in your cart and buy it! You won't regret it.

UPDATE: So company apologized for faulty one, sent me a new one and HOLY COW this does work amazing so much quieter than the first one! If I didn't see the bubbles I wouldn't know it is on! So I have to say now that I must have gotten a dud the first time because it was never this smooth or quite. Also customer service is wonderful. Company that stands behind there stuff! Can't beat that! So I would have to say now that I would recommend this even if you get a faulty one they will set it right. Now running three filters (Two 20gal and a 10gal) and an air stone, may even be able to add two more air stones like I want with this flow. So this worked pretty good, not really quite unless on the med to low setting, to power a few (two 10 gal and one 20 gal) sponge filters for two months. Although about a week ago in the middle of the night we were awoken by an extremely loud buzz (almost mini chainsaw loud) now I have to combine all four lines just to run one filter.

Love the ability to have vastly different flow rates in each of my aquariums with a single pump. Rather noisy, though, at full power but with balanced flows, it can run at medium power very effectively. Been about a year and, other than the racket it makes when fully engaged, it is a good pump.

Quiet, good air volume, and value. Yes it blows.

Plenty of power for all 4 ports. I really like the dial on the top. Easily adjust the air flow. Easy to setup and connect hoses.

I love this pump it is so powerful that it keep blowing off the hoses, even on low setting. The only problem I have with it is that it is very loud. My tank is in my living room, even with it placed in the cabinet stand it can still be heard. If you want a strong pump this is it. Update 11/9/23 the pump just stop working on both end. There is no air flow what so ever, and it is extremely loud. I am no longer using it, and have had to buy another air pump. I am very disappointed and dissatisfied.

This worked perfectly for my custom hydroponic grow set up. Tubing is the same size as a standard drill bit making installation look neat. I was worried the air flow from the device wasn't strong enough but it seems to output more than enough air for all 4 hydro units.

Excelente producto lo usé para mi pecera de 55 galones
