Which Pump?

[nessar]

Well I've just taken my new Hagen Elite pump set back.

One of the valves didnt work, letting water go back up the pipes, and the whole thing was so noisy that after 15 minutes I had to leave the room (which isnt very convenient as its my bedroom!). And that was after shoving it in a bag of gravel so it couldnt vibrate the floor and tank, and smothering it in two towels.

I saw on another post that tetratec and rena pumps are supposed to be quiet. Are there any that are SILENT? Because I'd prefer to put it on during the night too, but as I said it's my bedroom and I'm quite a light sleeper.

Obviously I'm looking for quality too, something that will last.

Also what size? The reason I ask is that my tank is 60/63 litres, which I think is about 15 gallons. Most pump companies seem to have one that is f0r tanks up to 50 litres, then the next one up goes up to 100.
The Hagen one was for up to 75 litres, and had two holes to plug the tubes into. Using just one made quite a current in my aquarium, and filled the entire surface with bubbles after just a few minutes, so I'm guessing it was too powerful. I doubt my fish would be able to swim straight if I used both (I dont actually have them yet so couldnt test this). I think I'd rather a stream of oxygen, rather than a cascade.

Please help! even if you can only answer one of my questions

I find the Renas that I have are quite quiet but they are not truly silent. If you get one rated for a larger tank and use the adjustment knob to turn the air flow rate down, they are quieter than if you are trying to get all of the air from them that you can. The ratings on their boxes seem to be in terms of how many standard air stones they will support at various depths, which I find much more revealing than the air pumps that are rated for various gallon or litre sized tanks.

Thanks would a betta appreciate a lower air flow too? I'm getting dwarf frogs too

I've got Elite, Rena and Eheim air pumps. The Elite is by far the loudest and because of that I don't use it anymore. The Rena and Eheims are virtually silent, though with either some low level hum can occasionally build-up, though that seems to be resonance as opposed to mechanical noise coming from the pumps themselves, as just a slight relocation of the pump or the tubing always brings the silence back.

anyone who has tetratec got any info for me?
