UL40

2 years old, no problems, Adjustable flow with knob on back, 2 air stones provide nice flow of bubbles, guppies. Mollies in 20 gal tank like the bubbles. Low noise level, pleased with purchase.

The best air pump, very low noise level and powerful. I’m running 1 large double sponge filter, an additional smaller sponge filter and an air stone with this pump. I bought the smaller version of this pump for my other tank as well which also has 2 filters. Highly recommend this product !

I’ve had this about a month and so far so good. I like the dial knob to turn it up or down. The water stones work good. The tube was good. And the check valves and splitters work. I have it connected to both stones and then a splitter for the skeleton bubbler. Works great on the lowest setting and is not loud at all.

Update, I've had this now for a about 3 weeks. It has gotten louder & pushes less air than when it first arrived. It's fine for my air stone, though not pushing as much air there as it was originally either. But isn't pushing nearly as much water through my sponge filter as it was a couple of weeks ago. When I first got it, I only had the dial set about half way up. Now it's all the way up & still not moving as much water. I am going to rinse the ceramic filter media & shake it around a bit & see if that helps. I'll update again if it does but I'm not super hopeful.It isn't a ton louder, but enough to be noticeable & it hasn't been long. I'm going to build a little noise box for it & I'm sure that will eliminate the sound but I'm bummed to have to go through that effort.The change in noise doesn't upset me that much. It makes sense that it won't be forever "freshly oiled quiet". It's the apparent change in air pressure that's concerning me. This air pump is powering two of the most important things in my tank to keep it livable for my fish. The air stone (I'm not using the included air stone but one I had previous) & the filter. If this pump fails, my fish are in trouble.I am removing one star for the faltering power. I will say though that some of the reviews mentioned the hose attachment points breaking off with light handling. I tried switching my hoses around to see if anything was loose & connect the shorter of my two hoses to the filter hoping the lesser distance to travel would make a difference. I held my breath when I did it, terrified that it might snap off on me & leave me with a completely unusable pump. I am happy to report that didn't happen. I was able to remove the well stuck-on hoses & reattach them without anything breaking. I was careful to pull straight back when I did it.---------Seems like every pump I looked at here had split reviews. This was no exception & it made me nervous. Why were some people saying it was nearly silent & pumped air beautifully & some were saying it was horribly loud &/or didn't pump enough air for even the tiny air stones it comes with?I still don't have the answer to that question, unless some are getting defective pumps. What I can say is that the pump I received is everything I hoped it would be. Our old pump was loud from the time we got it & got louder after we'd had it a while. Had ended up wrapping a rubber band around it, which seemed to have better secured the housing & stopped some level of vibration, but it was still noisy & annoying. We learned to live with it.I made the decision to switch from a carbon filter to a sponge filter. I have hard water & even though I'm now using half bottled water, the PH is still too high. I'm using Catappa leaves (indian almond leaves) for the tannins in an effort to bring the PH down to a friendlier level. However, a carbon filter will remove the tannins and any beneficial affect they might be having.A sponge filter will clean the water without removing the tannins, but that meant I needed a second air pump. Just got it today & set it up & while the filter will take time to be effective, I'm already over the moon at the decision.There is no more constant, loud drone. I had decided that if I had to I would build a foam box to house the air pump & cut the noise (I have packing foam left over from a computer. The dense black kind with large points, perfect for absorbing sound) but I'm pleased to be able to say it is completely unnecessary with this air pump.I removed our old pump, connected this to both our long air stone & the sponge filter (I bought this one https://www.amazon.com/gp/product/B07RJP2XB5/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1) and I am so impressed!I set the dial to medium and even at that setting the air stone is pumping out easily 2-3x the bubbles it was before. The filter is flowing beautifully. And the whole set up is nearly silent!!!Everything arrived in perfect condition. All the necessary accessories, though I have no need for the spliter or the additional air stones, the check valves were a nice inclusion.I really couldn't be happier with an air pump. I don't know if some people got defective pumps or they didn't set them up correctly somehow (though I'm not sure how you can screw this up). I'm thrilled!It's so quiet I'm genuinely thinking I eventually want a second fish tank in my bedroom.Just to be clear because I know when the reviews are split like this - half great, half horrible - it brings up questions. I paid full price for this air pump, I was not solicited to review it in any way.

Works great, runs two air stones or sponge filters (or more with a splitter). Adjustable air flow and very quiet. So much better than my old pump and fair price. One drawback is the design is kind of large with the power cord coming out of the side instead of the end, so won't work for tight spaces and you cant adjust flow for each side separately.

Quite, and works very well, my fish love it.

This air pump is very very quiet. I bought it for a 10 gallon tank. It has two air openings (twin outlet) It is very powerful but still very very quiet. It comes with plenty of tubing and two air stones, two check valves, a T bar and a dual bar (connectors) if you need them. I love the multi- speed control of air with just a turn of the knob. I bought it for a hygger Fine Mist air strip . I like the air strips better than the smaller stones. I can have a fine mist or what seems like tons of bubbles with the turn of the knob. If you are not happy with the amount of bubbles, it's not because of this pump, but the quality or type of air stone being used but always remember for all air stones, you get the best results when you follow instructions, because air stones should be soaked in the water for an hour before even turning the air on to them. I have seen 30 -45 minute wait times too. At the minimum wait 30 minutes. Also air stones depending on the type need to be cleaned or replaced every so often, so read the instructions on the type you buy. I would buy this pump again for other tanks .

I’ve had this for only a month, hooked a sponge filter and airstone to it. The airstone side continued to work perfectly, but the side with the sponge filter gave out and no longer blows any air. Outside of that, it worked great, wasnt too loud, and the filter was able to create a noticeable difference in the water quality so I’d say it works well. Probably just cant handle anything besides the airstones it comes with. I also ordered the one suitable for 10-100gallons, seeing as i have a 60 gallon tank.

Louder than expected. Also its only 110V rated. You need a transformer to step down from 220V in a 220V voltage supply countries.

I recently purchased the Pawfly Adjustable Aquarium Air Pump for my 15-gallon freshwater tank, and it has exceeded my expectations. The build quality is solid, and it comes with everything you need to get started—air stones, tubing, check valves, and connectors. That alone made setup quick and hassle-free.One of the standout features is the adjustable airflow control. I can easily fine-tune the oxygen output depending on the needs of my tank, which is a great touch. With two outlets, I’m running air to both a sponge filter and an air stone simultaneously with no drop in performance.What really impressed me is how quiet this pump is. It hums very softly, which is a big relief since my aquarium is in the living room and noise was a concern. It’s powerful enough to handle tanks up to 100 gallons, so I know I have room to expand if needed.After using it daily, it’s been consistent and reliable, maintaining excellent oxygenation in the tank. My fish are more active and the water stays clear. Overall, this is a fantastic air pump for the price, and I’d definitely recommend it to any aquarium enthusiast.

Me gusto el producto por que es justo lo que necesitaba para airear correctamente una pecera de 50 litros, no hace mucho ruido, no se sobrecalienta y la compre en oferta, el kit incluyó válvulas check que evitan el regreso del fluido en caso de corto, y también vino con manguera suficiente. en general muy recomendable.

Me gustó mucho el aireador, realmente genera suficiente aire para las 2 salidas. El controlador de burbuja es muy bueno, puedes reducirlo mucho o aumentarlo, yo lo establecí en aproximadamente 1/3 del total, ya que creo que es mas que suficiente para mi acuario. En mi caso la manguera fue muy corta, unos 30 centímetros más sería excelente, pero por ahora lo dejaré así pues logré acomodarlo bien. El ruido es leve, las gomas ayudan, pero si es notorio el "rumbido" del aparato, si eres una persona que no soporta el ruido blanco, intenta colocar algo para que no haga ruido o buscar uno que sea más silencioso, en lo personal no es molesto para mi en ese nivel de burbuja.

I was pleasantly surprised how high quality this pump feels. It feels heavy and solid, but is small enough to fit behind my aquarium. I can easily access the dial if I wish to turn it up/down. You could also hang it on the wall if you wish.I love how it comes with everything I need: tubing, check valves, and air stones. When you go to the store, you have to buy everything separate so this was really awesome.I also love that you can adjust how much air it puts out. I have it on the lowest setting and there is lots of air.It is very quiet, it sounds pretty loud in the video as I was holding my phone right beside it but when you are just sitting in room with the aquarium, you don’t even notice it. My filter is louder than the pump.I also love that it has two outlets, so I can add something else if I wish. With the T connector I could add two more bubblers for a total of 3 but I don’t need that much in my 10 gallon.I am very pleased with this purchase!
