    • Works great. Plenty of air pressure for my bubbler.
Style: 635GPH(40LPM)
I’ve been using this for our koi pond for months now. Good air pressure, quiet, my fish are happy. It comes with a multiple output header, would be nice if it had a single output connector as well. I just plugged the unused outputs.

The media could not be loaded. Look at photo, about 17db when turned on. Too loud to run in open indoor. Might work if use outdoor and run the line inside. Very sturdy build. Wish it's not as louded. I tried open all line or closed all lines, the noise level stays the same. Doesn't come with adjustable valve and instructions manual didn't mention the need to install blow off valve to prevent back pressure build up. ... show more

    • GREAT AIR PUMP
Style: 635GPH(40LPM)
The media could not be loaded. This air pump was a great purchase. It’s not very loud and provides great air flow for multiple items in my 80 gallon tank. It’s much more than what I need, but after getting multiple smaller ones that stopped working after a couple of months….I am very happy with this purchase. ... show more

I've learned that aeration is key to a healthy pond and this pump delivers a good amount of air, it's quiet, and has been on 24/7 for a year now w/o any problem. Good value for the price.

    • This is a gem for indoor hydro setups! Super quiet, lots of air!
Style: 635GPH(40LPM)
I love this little pump. I replaced a pair of 4-port Danner air pumps with this hoping it would be about the same amount of noise. I was absolutely blown away with how quiet this pump is, especially considering the volume of air it puts out. 5 stars!!!
