Noise and Vibration

[Col]

Hi all,

I have a Waterhome 5 (5 gallon) plastic aquarium, which is inhabited by a
few Dannios and Tetras.
To increase the water movement a oxygenation I was advised to get an air
pump of sorts. I chose a Hydor Aria pump which sits in the tank and draws
air from outside. The trouble is that it's very noisy, there is also a very
audible hum and a vibration which can be felt through the tank and floor.
(It is advertised as "guaranteed silent").
Will this noise and vibration have any harmful effects on the fish?
I think the tank is too flimsy and that is why it's resonating, either that
or the pump is faulty.

Any advice would be greatly appreciated.

Regards,

Col

I have 2 of these, and both of them were noisy.
However, after dissembling the impellor and putting it back in properly, the
noise disappeared.

YMMV

Hi 2pods,

I've tried splitting the unit and putting it back together a couple of
times, but it was the same. Do you mean stripping it further than just
taking the top off?

I took the top off and got the impellor out, then pushed it back in.
It hadn't been put all the way in.

=============================
I don't think air pumps have "impellers." All mine had diaphragms and
flappers.

=======================
I would return it. A good air-pump should be just about silent.

Windsong,

It's not a true airpump, it basically an impellor that draws air from the
surface and pushes it into the water.

2pods,

Thanks for that mate will strip it down tomorrow. The flow of bubbles is not
constant at the moment, it comes and goes at the same time as the noise. I
think you may have the answer. Will let you know. A bit disappointed really
as I chose this over an airpump, which was only slightly dearer.

regards,

These have impellers which draw air down a tube.
Baically it's a venturi.
Think of a small powerhead sat in the gravel, and there you have it.

I didn't know where to find it on that website, but I know I have not seen
anything like what you're describing before. Is it something new? I'm
trying to picture it......

Sorry Carol, the link only takes you to the main page :-(
On the page menu, go to products, then airpumps.

It's fairly new
I've got 2., a 4 and a 3 (which is weird 'cos I ordered a 1)

========================
I see! Very interesting. :-) I wonder if they last longer than the type
with the diaphragm and flapper. Even when you replace the parts they never
work really right or "good" again.
