HITOP First Impressions
I DID soak the stones.
I was going to buy 3 small air pumps to power 9 sponge filters when I saw this pump. Buzzing, humming, vibrating- they were driving me nuts! Yes it obviously makes some noise-but not at all as much as I was anticipating. This seems to be a good little pump that really puts out some air! We can hear the tank bubbles, but nothing noisy from the pumps at all. I guarantee the fan will help it's shelf life. I own Whisper 10, 150, 300, Eheim 400, and Fusion 700.

HITOP Final Thoughts
I hope they last!
And one to the additional accessories for extra oxygen output only. But if it's in another room, it’s not bad at all. Apparently the dome shape plays a significant role in noise reduction. I have this in our small aquarium with an LED bubble stone. I currently have it in a closet to grow aquatic plants and brine shrimp. The pressure isn't as great as I hoped. Great Product, BUT, its noisy and vibrates like mad on its rubber feet.
