Hope i could helpI have used 2-3 air pumps and the questest I have used was Rena. They cost a bit more but are more then worth it.

I was thinking of placing the pump in the cupboard below the tank which is a juwel rio240 to hopefully shut out any noise.
Again thanks for the replies guys i appreciate it.
