NICREW UFO Aquarium Air Pump - Ultra Silent Fish Tank Aerator with Oxygen Pump & Accessories for Freshwater & Saltwater Aquariums - Perfect for Home, Office & Pet Stores

Great price, super quiet, really good power. I've had one running two tanks for about a year and it's still running great, like brand new! If needed I will buy again!!Comes with everything needed to oxygenate the water for my fish!Works great!This works very well but the tubing nearest to the device device is turning Brown. I. I would assume that it's probably probably from heat coming from the unit. It's visible so I can monitor it can monitor it but if it was not it would be concerning to me.. I'm not sure if sure if other units do this as well but this one sure does and I have not had it that long. The noise level is OK it's not totally silent. And I've had no problems Otherwise .Purchased dozens of these for educators! Absolutely no complaints ... great buy!I bought the double unit----anticipating a lackluster pressure at this price point. Glad I did as it works great for my needs. A cup of worm castings, a teaspoon each of blackstrap molasses & fish emulsion, a few gallons of rain water & off to the races----WORM TEA ON THE WAY :)P.S.If your unit seems like it's not producing many bubbles, make sure the valve is pointed the correct way (black needle towards the pump)......works MUCH better that way,lol.I was replacing an old Wisper pump and this one is so much quieter. So far so good. It is looking good so far.I wish it had come with a flow regulator switch. I had to buy one. The bubbles were too strong for my tank. The cheaper Tetra pump I got a few months ago came with a check valve and flow regulator switch. Just a cheap little switch the manufacturer could throw in the box.I hate this air pump. As others have described, it was ok at first, quiet enough (they have to make some noise). But I've had it a year now and it is just the worst air pump I've had. At the new inflated price of 40$ (I paid 26$ in 2021), please spend your money elsewhere. This is just my back up pump. I don't need it often, I do not run it daily. But I had to pull it out this week for temporary use, and I can't even have it on while I'm working in the same room. For the record, there is another tank and pump in the room causing no sound issues at all. I'm buying a new pump, because even as a temporary measure... this thing is awful... so I had to warn you all.Very happy with this purchase.The pump itself is a normal size not oversized like most dual air pumps. Price is very decent too.Came with two hoses and two air stones also.It is quiet and give out a very good amount or air.I have the 2 outputs split into 2 each one sponge filter and one air stone on each.. so its the equivalent of 4 regular pumps.I have other Nicrew products such as led lights for my aquariums and never disappoints.Good product!Dual pump outlets are a great feature. Bought another shortly after getting the first one because I liked it so much! I use a sponge filter on one line and a airstone on the other. Great agitation on the water surface. If yours vibrates a little and is a bit louder on a hard surface it is easily sound proofed with a sponge or fabric placed under. I used a filter media under it and it made it super silent.
