Fish tank in my Bedroom , I have a age old problem , Advice please.

Advice please i have a bit of a situation , i have just put a 2ft tank in
the bedroom ,i've cycled the tank and have filled the tank with a 50/50 mix
of clean and my other fish tank water , my filter is brand .

I have one fish in there currently , but will be stocking this tank with
around 12 -14 small fish , neons , guppies , a couple of plattys and i do
like the tank in the bedroom , but i imagine you've guessed my problem ,
although the filte is not loud or does not seem to be during the day , when
it comes to the dead of night , i can hear it , hummmmmmmmmmming away in the
back ground , i can see it becoming a bugbear .........so i have too options
, i have a nice little suitable space downstairs in my front room , where i
can put the tank .

Or would it be possible to put the filter on a timer so that when the light
goes off on the tank the filter turns off , this i would happen during say
12am - 7am , for 7 hours, but i'm unsure if this is fair or suitable for the
fish ,i've been round the houses and put some filter sponge between the
filter and the glass on the tank , that did cut the nose down a little , but
you guys i'm sure know , that at the dead of night , if you hear a pin drop
you can kinda hear it..........

I hope this will not cause a stir of ppl shouting at me for even making the
sugguestion , my big tank is in my 2nd bedroom and of course the pump is on
24/7 , but i can't hear that pump in my sleeping bedroom.

Sooooooo guys do i have two options , both been okay and fine for the fish ,
or is it a very bad idea and i should simply move the tank downstairs , if i
can't live/sleep with the hummmmmmmming noise from the filter.

Advice welcome.
