Re: Noisy air stone :-(

I've read in a couple places where problems with the air-line or not having
a back-flow preventer (not sure of what its actual name) in the line causes
the air hose itself to vibrate loudly.
Also, if the airstone is directly on the tank glass this might cause its
normal soundless vibration to rattle the glass and make a lot of noise. In
that case, leave it on top of any substrate (gravel, sand, whatever) that
you have in the tank.

Just a thought that it might not be the airstone itself.

Today I purchased an air curtain which has suction cups on it to stick it to
the glass. I must say, what a difference! The air stone was the problem -
it was just resting on the gravel, although I had made one attempt at
burying it a bit, I didn't want to stir up the gravel too much. The air
curtain is now working tremendously and the noise just a slight fizz. I can
deal with that much better!

Thanks for your responses on this.

I have the same airpump and started with the Aqua Fizzzz stone (made by
Hagen), but as I don't have any gravel or sand at the bottom of my tank, it
created a vibration against the glass, so I turned to the Interpet Aqua Air
just because it had the suction cap (I couldn't find any others with this)
as this would keep it off any surface.

And yes, I have the same noise as you did, but it is better than with the
other stone. I may look at the air curtain as a replacement as you have,
what brand did you buy? Although I guess they are all the same, after all
it only seems to be a tube with holes in.

The Air Stone I originally bought didn't come with a suction cup, I just had
to rest it on the bottom of the tank.

I'm afraid I can't tell you which brand air curtain I bought as I've thrown
the wrapper away! I would agree with you though - they all look the same so
are probably much of a muchness.
