I saw it posted here and I can't find it now, and yes I searched.... It basically told how and what size Spike coil to use with a Unitank. I'm getting a 14 gallon, per SS the smallest batch they say I can cool is around 8 gallons. I want to be able to do 5 gallons, 3 if possible for testing recipes. But I also want to make my 10-12 gallons. Can anyone help me?
