Return pump in my sump!

[Mellow]

hello people,

I'm currently using a dymax 2500l/h return pump in my sump...but it's producing alot of humming sound. Was wondering if anyone can recommend me a return pump which is totally quiet or some remedy for the humming sound?? coz my tank is just 1 foot away from my bed. very irritating!!!..heh.. thanks in advance!!!

Just put a filter pad to act as a cushion under your pump, its vibrating against your glass and causing the humming sound!

oh, sorry. thought i posted in marine aquarium...opened too many windows until i got confused..anyway, thanks for the advice!

hey AT, u got any brands to recommend which is totally quiet? the pump already has suction cups underneath and i thought that will be sufficient to stop the vibration and humming?

there isn't such a thing as a pump which is totally quiet. even if there was one, with wear and tear, it will become noisy again. (=

Go and get a 5cm thick kind of blue filter sponge, those used in koi pond, and sit the pump on top. There aren't any pump that is total silent unless they are small tiny powerless pump. The humming is cause by the vibration of the pump. Its also depends on what your sump sit on which cause the humming to increase.

thanks alot people...did just that(pump sitting on sponge) and works perfectly fine!!!

just to add...will the sponge which i've added end up as a nitrate factory like bio balls do???

[Hon]

Just add a small piece enough for your pump to sit firmly on top. Don't think such a small piece of sponge will becom a nitrate factory. If you doubt, wash it every mth. ...
