hi! was wondering if you figured out anything more on the tank heaters. I have 3 switches for grey black and fresh and the 1st time i turned them on they lit up blue. Since then they haven't and I they are turned on and the temp outside was 18 degrees. I jus want to know if they have to be lit up to know they are working. Or if they are actually working.
Thanks for any input you might have learned and for sharing.
