Canoetrpr,
Give it a shot and see what happens. Trout aren't terribly expensive if you do lose them, so it's worth a try.
And like Pondpro I only know what works for me, and my density of trout is 5000 lbs. per acre upon harvest, so I have to have flow through -- that is-- until I get my coldwater partial recirculation system going.
Keep us posted!
