I just got a new RBI cb70 rack and herpstat 2 t-stat. The rack came in last week so I set it up just to let everything come to temp. The t-stat came today and as I read through the manual I saw that they do not reccommend using aluminum tape to secure the probe. Unfortunately they don't say what they do reccommend, so what is the preferred method for securing the probe to the heat tape? Also, all three tubs are reaching different temps, so what tub should I attatch the probe to?
