AquaMiracle 6/8/16W Quiet Fish Tank Air Pump 200/317/475GPH High Pressure Aquarium Air Pump Commercial Air Pump Pond Aerator Bubbler Hydroponics Air Pump

Definitely a much higher flow of air and can easily operate more than 5 lines at full volume. Probably a 9 out of 10 or quiet operation - which is good for such a heavy duty unit.

Yes, this unit is loud, so I relocated it to the basement. It's located just over 10ft. away from the air stones being used. I have the pump operating at 60 - 70% of it's maximum output. I'm using only 2 of the 6 outputs (one for each 4" air stone) along with the output and Distance, the pump operates unbelievably well. For the overall rating see photo I think you may agree.

The media could not be loaded. Great product. Pumps plenty of air for the large bioreactor that I use. A lot quieter than the last all metal one I had. Thank you

This pump is powerful enough for eight lines. I bought an 8 output manifold right after buying this and it handles 8 air stones very easily with a large volume of bubbles. The feet it is sitting on do a very good job of dampening the vibration, to like… none. I think it is noisy but certainly not as noisy as the 4 pumps it replaced.

Blows a lot of air.Gets very very loud

I got the air pump for a 90 gallon in April of 2024. It worked fine until about a month ago it stated with a quiet high pitched noise. In short time it backed very loud. It was like nails on the chalkboard. I tried to open it up and see if there was something obvious noothing. I didn’t really do much. It was quiet for about 5 minutes then the noise was back.I think should at least last a couple years. This made it 8 months

I have it hooked up to my hydroponic systems. There are different sound levels. I marked the controller with paint so I can turn the dial to the level I want. Even at level 2 that I set, the sound level is like the fridge when the freezer is on. level one you can’t hear unless you walk right up to it. The loudest setting is very loud though. Highly recommend because I have this hooked up to16 2L pods and even at level 2 it’s bubbling all the containers, while still being cold to the touch. Quality is great. Compact size and it think it’s worth the money.
