Silent Air Pump Possibilities?

[mustrum]

I just switched over to an air powered sponge filter (my Killies didn't appreciate the current with the powerful internal mains powered filter). Only problem is the noise. It is an Eheim 100 - and I forked out extra cash for the brand name as the assistant assured me that it would be silent!

Any ideas on what to do? I really want "inaudible", when I say quiet. Is it worth trying a Rena pump instead (these were mentioned when searching on this)?

These are really quiet. You might want to try them.

Place the pump in a seperate room (I have one in the loft) and have the airline run to the tank.

That seems like a good idea. How long is your airline run from the pump to the tank? I think the run might be too long from my loft.

I have a run of about 12 feet down and then 12 feet along the floor to where my skimmer is.

No to offend anyone, but it's pointless asking for a silent airpump as there are too many other factors involved which make influence how quiet it will be. Depth or tank, number of airstones, whether the pump is in a cabinet or not, size of room it's in, layout of the room etc etc...all to some degree influence how quiet the pump will be.
The only way to do it so it's absolutely quiet, as Andy says, is to place it somewhere you definitly can't hear it ie, outside or in an attic or somewhere.

Wrap it in a hand towel...

I recommend Tetra APS pumps. I have 2 x APS50's running on my 108l for some occasional bubbles, they don't get used that often tbh but when they are on, you cant hear anything but a very slight hum which is so quiet after 5min I don't notice it anymore. I had an Elite 2 outlet jobby before these and that was just stupidly loud for a "silent" pump.

The pumps are all in the cabinet with the EX1200 canister, and the whole tank is in my bedroom. I did have them in the hood but after I nearly killed myself taking the heater out I moved all the electrics except the light starters into the cabinet.

Well, yes that is the solution.

Mind you, I suppose it is possible that the manufacturers could just measure the noise produced for a default amount of work that the pump is doing, at a set distance from the pump. Then you'd at least have some figures to compare... I checked how noisy all the bits were in this PC, before building it. That seemed to work OK!

actually Rena and Whisper air pumps are generally very quiet. They impregnate the casing with air bubbles that act as insulation. Also a lot of the noise is from the actual bubbles in the tank.
As for the Eheim being noisy I would take it back and try another one, or swap it for a Rena.
Don't wrap it in a towel as they can overheat and start a fire.

My personal experience after 12 years using them myself and 8 years I was in trade, is that Rena airpumps are the quietest you can get and they certainly resulted in the most happy customers

I have found Tetra, Rena and Eheim pumps to all be very quiet. The only time I notice a noise is if they or the airline is vibrating against something.

M,


Whatever you do I would be inclined to bang a hole in the bottom corner of the wall behind and stick the pump in the kitchen. That avoids a long run from the attic and the pump doesn't matter in there and even with a quieter pump you could still get some sound if you have it in there.

That's got to be the best solution.
