I've got a 150g tank running a sump , I want to make sure there is plenty of oxygen in the tank but don't want any equipment in the tank. Can I run my airstone in the sump? Will the water still be aerated enough once it reaches main tank ? Thanks
 
That should be fine. Just keep in mind, the amount of O2 exchange will be dependent on the surface area of your sump.

I ll get exact measurements but at a guess the sump looks 36 x 18 . The pump I have for it is way more powerful than what's required for that size I think . Going to be having a busy active tank so need plenty of oxygen . Another option i thought is put the air stone in down the weir but would prefer in sump .

You should be fine with the air stone in the sump

Just curious, how is your return line currently rigged up that prevents you from oxygenating the water via surface agitation?

A spraybar, as already suggested, is a possible option for you then. Positioned just above the water surface it'll create a right stir. Only slight downside could be your gph turnover and positioning of your tank. If you have high gph turnover and your tanks in your front room you might need to turn the volume on your tele up!! My tank is in my front room and my spray bar was brilliant, but loud. I ended up taking it off and now the end of my 3/4" return pipe just sits parallel with the water surface and is a lot quieter. I've fixed it in place with suction cups attached to my tank bracing so it can't slip under the surface and potentially flood the place if we have an outage and i'm not at home.
