AquaMiracle Aquarium Air Pump Commercial Air Pump with Aluminum Housing, 600/1000/1200/1750GPH Fish Tank Bubbler Pond Aerator for Aquariums, Ponds, Hydroponics

I’m using in an outdoor koi pond. This is the third brand/ model I’ve tried and I’ve been getting about 2 years per pump on the others. Will see how this one holds up. Value is on par with others I’ve tried. Power/ air flow is excellent, it’s easily the most powerful one I’ve had. It is pretty loud, but being outside it doesn’t bother me. Comes with 6-way manifold with shut offs making this pretty versatile. I’m just running 2 air stones and it’s doing great so far keeping my pond from freezing over.

It works wonderful, it's not as loud as other people say, I like the big amount of air it delivers, and it barely gets warm, I'm using all the outlets, with big 2x4 air stones, I'm super happy with it

This is the best air pump I have ever owned it's a little loud at times so I just move it and it quites down again I'm buying my 3rd one now cause I need a strong multi port air pump for my 60gal tank I have a 50gal and a 30 gal also best pump for your money lasts a long time too!!!

I suppose I shouldn’t be surprised by the noise, but it’s more than I’m used to and seemingly loud given the power level. The power is pretty good but I expected a bit more, if I’m being honest. The heat level is not terrible, but I wouldn’t hold it to an extended period. Overall, it seems well made a provides a good amount of air, but I wish it had a bit more padding to reduce the noise.

I use it to oxidize a 500 gallon water holding tank. Use it an hour a day to keep the bacteria down. Works well.

First pump was shipped wrong, seller sent replacement VERY quickly. New pump has plenty of power for multiple air stones in multiple fish tanks. Pump is alittle loud for a bedroom, but great for my fish room or multi tank set up.

This really met and even exceeded my expectations. Was looking for aquarium air pumps that could supply a lot of bubbles for my airstones and this is the only one that was able to fullfil that need. It even has a 6 gang attachment and so far I am only using two (2). Working great and better than all of the other obes that I bought. Not really super quiet but not extremely loud. You can say that the sound is a tolerable monotonous hum. Would buy again.

Will overheat and shut off if you don't keep a small fan blowing on it. Other than that, works like a champ.

Good strong pump

It stopped working on Day 1, after being on for an hour

Para lo que necesitábamos le falta un poco de potencia pero los complementos con muy útiles

Muy funcional, pero muy ruidoso, no lo recomiendo para uso casero. Para uso comercial creo que va perfecto.

excelente mucha potencia mis peceras están plenamente abastecidas de oxígeno con este compresor
