I'm no expert and I have.a limited budget for my hobby but I got a herpstat intro for my rack and have a 32gal. display tank on the top shelf. I heat all with 4inch flex watt heat tape. My probe is taped down directly on the heat tape with elect. Tape. I had to fool around with the temp. settings to keep the temps. In the tubs and tank within acceptable ranges but it has hi and low temp alarms and seems to work well. I check my temps with a fluker heat gun which gives me surface temps but all I have for ambient temp monitoring are those cheap tape thermometers for aquariums in the.tank. I need a thermometer with a probe but the tank and the tubs will ne different I'm sure. I guess I should put one in display tank and another in one of the tubs.
