Air pumps Inquiry

Post by Rodda Prime on Sat Mar 07, 2015 5:02 pm

Hi there!

I wanted to ask about the general consensus on different air pumps, my little 5 gallon isnt getting the surface agitation it needs with the HOB filter, the outake kind of waterfalls and it creates too much of a current for my little rcs, so i was think of adding a airstone and a sponge filter back up, I was asleep one night when the strangest noise came from the tank, which doesn't bode well for the filter >_>

Basically, I'm looking for a good air pump thats not too noisy, i got this one Marina Cool air for cheap on amazon but its so loud i can hear it from the stairs!

Any suggestions?

The less expensive (ie, affordable) pumps are generally noisy. They are loudest when they get back pressure - if the airstone is blocking, or if the diaphragm inside tears.
When I used them, I liked the ones with adjustable flow (you can turn down the amount of air), and I also liked to screw them into place.
The brand names? They tend to get relabelled. The ones from Hagen weren't bad, air and noise-wise.

I have basically always used Elite. For one because these were the only real brands available in Mexico before the Chinese came in.

These only make noise when they 'move' to a place where they touch another object, like the metal of a stand. Gary's suggestion to screw them in place (they have a provision for that) is a very good one to avoid this.
