The "hard" air stone I first used caused a lot of noise (seemed to vibrate in the tank), so I switched to the soft, rubber-like material which is a 5" long, thin tube that I got at PetSmart. It clogs quickly, and even when clean it makes an irritating humming noise; I think the holes in both of these bubbles are too fine. I'm convinced it is the stone itself and not the air pump.  Online I found a Kordon medium-sized bubbles bubbler as well as one that makes fine bubbles and coarse-sized bubbles.  Has anyone tried these?   Or does anyone have a suggestion for a quiet air stone?

My air stones have always been noisy, but using the same pump I have sponge filters running and those are silent. Obviously not an air stone, but still produces surface agitation for oxygen going into water.

Hi Ruthy,  Thank you for your reply.  I am not familiar with using sponge filters.  I Googled them and found some information.  I would need a fairly small one, I think, for my 20-gallon; it looks like some of the sponge filters are huge!  Do you, or does anyone, have a brand to recommend, a source from which to buy or a website that is particularly good at explaining them?  Thank you very much for your help.

I Have some issues with certain things Carl states on his site. One is in that sponge filter article. there is no way any appropriately sized sponge filter has more surface area than a properly set up UGF. As for the quality of the ATI sponges, I used them for many years. Over the past two plus years I have switched out almost all of them for Poret foam. I use both the Hamburg Matten filters and the Poret cubes. You can find these products here:

I strongly urge you to read the articles on the site especially this one  http://www.swisstropicals.com/?p=1201 and then this one which actually runs a comparison between the ATI and Poret foam. Incidentally, I rinse my ATI sponges every week, for the Poret I do it once every 3 or 4 weeks.

I think Mr. Spotte would also agree with you on a properly set up UGF  Wink

Thank you for your comments.  Who is Mr. Spotte?  Is there a location on this site that will define all the acronyms in use?  Thank you!

Stephen Spotte is an acclaimed marine biologist, aquarist, naturalist and author. He has written several books regarding fishes, aquaculture engineering and support system functions and methods and marine life. You won't find him the list of acronyms, but him, Martin Moe and several others should deserve an honorable mention within the list  happy

Rereading some of the replies, I think you also meant UGF acronym...sorry.. 'under gravel filter'.

Thank you, Russ.  Another question that popped into my skull while figuring out the air stone noise is:  does tank noise (from the filters or from an air stone) negatively affect fish?  I would think that day-after-day, 24/7, tank noise would be very stressful to fish. I read that fish can hear and of course can feel vibration, but I'm curious to know if studies have been done for noise or vibration in a home aquarium.  Just curious if anyone has any knowledge of this.  I know studies have been done on fish in the wild.
