If any one can help me, it would be great.
I need at least 2 weeks worth of recording , could you also answer these other question
What type of thermometer you use?
What type of tank it is? e.g tropical, salt, cold water
How many litres is the tank?

At lights on the temp is 26.1'C, lights off 26.3'C. That is consistent since the tank has been setup.
