Air pump ?

[River barbel]

Hi

I'm going to extend my pond next year to have it above ground to have a window.
I not be putting plants in the pond so got me thinking will I need a air pump, my filted water that flows. Back in to the pond will fall about 12inch into pond will that be enough to put oxygen in ?
So just wondering how many have air pumps in there pond ?? And do u think I need one??????

I am waiting for the 4 port one and it comes with everything which would cost a lot more .

not this one .I like the fact it comes with absolutely every thing and they have a you tube video but have a store not far from me to see it in action ,but seems to be popular here as they were waiting for more to come in .geeze I get confused :razz:
