UL25

Adjustable. Strong air flow. Very quiet.

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.

this product hits most of the marks. great bubbles, easy set up, and quiet. i was a little bummed to read that it came with two airstones, when i only received one. one of their faq questions also says that the flow is adjustable and it is not. maybe that’s for a different item, but it showed up on the one i bought. i did have to pull it closer to the surface because of this so that my betta doesn’t get whipped around. i have a 5gallon btw. the one thing it’s missing is suction cups. it was a little difficult securing it in a spot with such a kinked tube. overall though, happy and my betta loves it.

Great Aerator for my fish tank! This aerator with a little stone rock is perfect for my 20 gallon fish tank. It can be used in even a 5 gallon tank and also in larger tanks. It is very reasonably priced and just as good as the more expensive aerators I have bought, and it makes less noise. You can also dial up or down the level of the bubbles, which is great and I cannot do on my more expensive aerators I will be purchasing this aerator again for my fish tanks. Highly recommend!

Amazing output. Has a dial to restrict air flow and 2 ports. It is very quiet!

The product appears and feels to have good quality, but sadly I can't say the same about the functionality. The pump barely puts out any air, I can't feel any air flow from it at all when I was just testing it out in the open; and even in the water it barely made any bubbles. It might as well be a $14 paper weight, I highly recommend buying a different product and saving yourself the time and money only to be disappointed.

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 dual air pump is ok. I'm using this with a sponge filter and an air stone in a 20 gallon tank and it works fine. The pump is louder than i would like when the knob is turned all the way up. In a quiet room it is loud. The knob does not turn the air off completely. I have another brand dual air pump which is quieter and the knob can turn the air off.

Fonctionne bien, légèrement bruyant (comme la plupart des pompe a air. Fait un léger hummm comme son, mais le son varie selon le positionnement de la pompe

You can compost 2, 5 gallon buckets of compost tea at the same time !! The best of the best and great price!!!! Wow wow wow
