Hey all, I noticed in some threads that people mentioned using one thermostat for multiple tubs? How does this work? Aren't you afraid that if something goes haywire in the tub with the probe, it will fry/freeze the snakes in all the other tubs? I know there are thermostats that allow you to put up to four tubs on them, and they have four probes, but I've seen people using one thermostat with one probe to run all the flexwatt in their rack system. This seems like a bad idea to me but is there something I'm missing?
