I have a really dumb question about how to read the temperature strips that you afix to the glass of a tank.
I know a digital one would be more accurate but I want it to be more natural looking.
Mine has dark blue on the 82 mark, mostly green with a little yellow on the 84 mark, and orange on the 86 mark.
should I take the average of 84 degrees or the 86 because that's the highest that has color?
thanks
