Most definately DO NOT BUY a LAYAL SK-9102
( 3w, 0.012Mpa, 2 Litres per minute )
it's like a jackhammer!
I only use it with a gravel vac as it's too noisey for regular airation duties.
-----------------
Peak Aquatics AP-1002 is also a bit of a powestation, but then again it does have 2 outlets and is adjustable hi/lo.
Too noisey for my bedroom that's for sure.
-----------------
Interpet Aqua Air MINI is pretty quiet, it's 2.5w but doesn't push much air. I have it in my bedroom.
