EcoPlusECOair 1 Commercial Grade Air Pump 793 GPH - 18 Watt Single Outlet with 6 Valve Manifold

I'm using this for about 2200 gallons. My fish are hibernating in extremely well oxygenated water. I ended up just using 4 instead of 6 because it pushes so much air that my 3.5ft pond is getting bubbles everywhere. I had a different kind that needed 6 and still had still water areas. This thing really pushes some air through. It's a slight hum, but this is an outdoor pond and I hardly can hear it. I have to walk to the pump house to make sure it is on. And it's much more affordable that the other brand we had. Our old one had a know that turned it all the way up or down and we had to have it on max all the time, so for us, this one not having that feature is actually nice because you can't accidentally bump it and turn the air flow down. I highly recommend this for fellow fish pond owners. My fish are all happily hiding in their rocks instead of trying to hibernate near the diffusers. Huge yay!

I got this to use in conjunction with my K40 laser cutter as the air driver for an air assist nozzle. It puts out a lot of air - more than enough to keep the nozzle clear and to keep things from flaming up on the bed.Things I like:- The air splitter it comes with is metal and the valves work reasonably well, so you can change the air output easily without worrying about breaking things- Puts out a lot of air- Seems ok so far in continuous operation for multiple hoursThings to be aware of:- If you turn it on without having the air hose connected, it's really loud. With the air hose connected it's still fairly loud and I wouldn't recommend it for indoor use in a place where noise might be an issue. I'm using it in a garage so it's not a problem at all. Be sure to place it properly on its rubber feet as well or else it will vibrate whatever it's on quite a lot.- As others have noted, it does get hot during operation, so be sure you have some ventilation for it.

I bought this for my koi pond, the heat here in the summer is pretty intense and I felt the fish would benefit from some extra oxygen! I first tested it inside. When I turned it on it sounded like a freight train! Of course my first thought was this is not going to be good!! However once I got it all installed outside the noise was minimal. Between the filter, the water falls, the birds singing etc you could not hear it. It really is powerful and my fish love it, they love hanging out in all the bubbles. The air stone is 6 inches in diameter and works very well.IT DOES NOT COME WITH THE AIR STONE YOU MUST PURCHASE THE STONE SEPARATELY.I purchased a small plastic container melted a hole for the tubing and another for the power cord and enclosed the pump inside the container so it will not become wet. It also comes with a bar that has 5 ports on it so you can hook up several air stones at at time if you wish.Highly recommend

The air pump works great it's a little on the noisy side but makes a ton of air, in the pictures on this page it shows air stones with it, You do not get any air stones or airline with the pump.

tl; dr: pleased with pump, came with metal 6-valve air tap, only 15 watts when connected to air stones, *much* quieter with long hose connected to air *inlet* to move sound away from pump.We just set up a small garden pond and after a week or so green moss started forming on the rocks and the water got cloudy. Aeration was a common cure so we ordered this pump, some tubing, and air stones. I had never used an air pump or done a pond, and was concerned this would be noisy, but didn't want to get a smaller type of pump because I wanted a lot of aeration and didn't want to do regular diaphragm replacement as the smaller ones require.Plugging it in for the first time inside, with nothing connected, my heart sunk as it was very loud. It also measured around 25 watts on my Kill-A-Watt meter, even though it's advertised as only 18 watts. It turns out that this is the wrong way to evaluate it. With hoses and air stones connected it only uses 15 watts, and is quieter. I placed it outside next to the pond and it filled it with bubbles, and caused lots of circulation as well. It came with a nice metal 6-valve tap, and I was only using three of them (two air stones, and one bare air tube with its valve turned down).The pump was still somewhat noisy though. I noticed the air inlet and read about the noise coming from that, so I connected it to an old garden hose (no water in it) so that it drew air from the end of the hose that was far away, and the pump became almost silent! I was pleased that this last nagging issue had been solved, and my concern over the noise put to rest.Unfortunately it didn't make any change in our pond's green moss growth situation, but definitely not because the pump has any shortcomings. This is one reason I got a powerful pump, so that if the moss didn't reduce, I would know for sure that it wasn't due to a lack of aeration.We only ran this for a few weeks (24 hours a day in Texas summer) so I can't say much about its long-term reliability. Zero problems during our use of it.

I waited a long time before writing a review, about a year-and-a-half now has passed. I have just purchased my 7th unit. All are still running perfectly fine as brand new. I am very happy with this product and have had no issues at all. I am very pleased with the power and the ability of this size unit to effectively run 6 Airlines seemingly effortlessly. I use it for Sponge Filter setups on indoor aquariums with an ambient temperature around 76° give or take. As for people complaining about noise or longevity I would challenge that by saying of course it's not going to be the quietest pump but it is not obnoxious. I cut the vibration down by putting a thick cardboard square underneath it. Yes they run warm but if all vents are half to three-quarters of the way open it maintains a reasonable temperature. I have invertebrates in my tanks and I like that the nozzle is brass and not copper which is toxic to all invertebrates over time... I would recommend this to anyone who is running multiple tanks indoors. Hope this helps with your decision. That's why I wrote this review. Great product!!! Great bang for the buck!!!

very noisy, but it works great with good air flow for my application. Cannot tell about longevity, but worked ok for 6 months, intermittent use.

hace ya 2 meses que tengo la bomba aireadora, a pesar que es ruidosa cumple con su función, la tengo un tanque de agua de 200 litros y trabaja durante 12 horas seguidas, esta muy bien

This is well made and powerful it operates quietly and pushes air deep into a pond or aquarium.

Lo utili e para varias piedras aeradoras de 3 acuarios

Excellent pump as far as noise level, if you have enough pressure. I love that you can link more than one together for better compression, but it shakes my house.Will NOT run 6 - 4” round flat airs tones, even with only 5 air stones if the stone is deeper than 1’ foot, it doesn’t bubble.Good value, know what you are buying. I suggest 6-2” air stones for a single pump.
