Yuri, how much ice is required to do this? I've also been recirculating ice water, but only after using the water hose to get the wort down to < 150', and even then, I melt an entire ice chest full of ice. If I started using the ice from the beginning, I don't think I would have enough ice to make it through cooling the entire 10 gal batch.
