If you brewed the Cooper's OS lager,then you're fine,as it comes with ale yeast anyway. More of a light pale ale. By the time you get a stable FG,it should be a bit misty. Give it a couple days to settle out more,then add your dry hops in a hop sack to keep things tidy. 7-10 days is normal for dry hopping right before bottling/kegging.
