Uniclife Aquarium Air Pump Dual Outlet Fish Tank Aerator with Accessories for 5-200 Gallon Tank

This pump has very good power - it pumps a good supply of air through my under gravel filter risers - which the last 2 pumps of other brands could not do. It is amazing quiet. I have had it for about 3 months and still runs like new - still just as quiet as the first day.I have not used the air stones yet - but they look like really nice stones. And the tubing was high quality - I would like to buy more tubing like this.

Works great after 6 months. Very quiet.Quieter than all my other pumps and very similar to Aquarium Coop pump. Flow adjustment is great.

Sound: One of the big draws for me was noise level, so when it said "quiet" that's what I was expecting. It's not loud, but still noticeable, especially in an otherwise quiet room at night.Setup: This was easy - cut tubing to desired length and attach to pump, valve etc. The tubes were a tight fit, so some force was required. Once they're on it's tough to get them off, so make sure to cut correctly the first time.Flow: Even on the lowest setting, dial turned all the way down, the flow is still significant - with only a filter connected, for the size of my aquarium, this agitated the fish. However, with both a filter and the included stone the attached, there isn't enough force to move the air through.

I’ve only used this pump for a short while but was very happy with it. I really like that it’s adjustable and it is pretty quiet. Of course, I kept it dialed down to the lowest air flow so I suppose it might be a little bit louder if it were turned up higher. One comment, I did have a lot of trouble getting the air hose on and off the pump and the air stone. Once I attached the tubing to the pump and the stone, it was almost impossible to pull back off again. I don’t know if it was something I was doing?? Also, it should be noted that the air stone it comes with is a bit large. My guppies seemed to like it and would swim back and forth through the bubbles. However, I had to switch the tank to house a Betta and I had to stop using the air stone. Betta fish are not strong swimmers and prefer calmer water. Consequently, they should not have an air stone in their tank. Especially a small tank like a 5 gallon (smallest tank a Betta should be kept in). Even though I am not currently using this air pump I still decided to keep it because I like it and will use it on another tank in the future. I do highly recommend it.

This is a great item. I run a sponge filter in my African dwarf frog tank. They prefer calm water and aren’t strong swimmers. This unit allows me to lower the amount of air being pushed from the sponge filter so the water isn’t too crazy for the little guys.I’m also impressed by how quiet it is! I usually buy a cheap mouse pad and set all my air units on that.The air tubing that came with the unit is awesome as well. It’s thick and durable. This prevents kinks very well.I did not use the air stone that come with the unit because I needed a smaller stone to fit inside my sponge filter. I believe it’s worth mentioning to others that the air stone is large. It wouldn’t have worked for what I needed but I’m hanging on to it for future use.I have only one complaint and that is that there is a pebble inside the check valve that rattles endlessly. I switched it out for a check valve I had laying around. I could hear it over the pump and it would have driven me mad.All in all I’m happy with this purchase!

Had this pump for a few days and it's working well, very quiet. I like the dial to control the air flow. Came with tubing and some extra items, too, so I didn't have to buy that all separately. Good value. We'll see how it holds up but happy so far.

Works great and is quite. Thanks
