I bought myself a TC-10 thermostat which will turn off my heaters if a set temperature is exceeded. My Heaters are set to shut off at 25c so i was thinking of setting it to shutoff at 26.5c. I was also thinking of wiring my lighting into the circuit so i have a easy visual sign if the max temperature is exceeded plus on the slim chance it is enviromental temperature causing the spike the lights won't continue to heat the tank. Opinions ??
