so i was thinking about this and ill give you an idea of what i want to do and see what you guys and girls think. I want to make a rack to house adult BPs and baby BPs so i figured to cut down on the frustration i would just use 41qt tubs for the adult male and females and shoebox tubs for the babies but i dont have the money to buy 2 thermostats and im not going to jip out on a good thermostat. now you guys said 11 inch heat tape for the 41qt tubs but thats far to big for the shoebox tubs so if i used 4inch heat tape and made 2 lines to make it 8 inch heat tape would that work on the 41qt tubs ? Then i could run every thing off of one thermostat so it would be 8 inch heat tape for the 41qt (2 lines of 4 inch HT) and 4 inch heat tape for the shoebox tubs what do you guys think ?

hope that makes since
