Query: Cools 6 gallons in roughly 20 minutes

Works great! I coil up the garden house in a bucket of cold water. When the temp of wort reaches around 80-90 degrees I add ice to the bucket of water where the hose is coiled up. This cools the water going into the wort chiller. Kind of like a pre chiller, but free.Great Price for this item. I couldn't find it cheaper anywhere else.
