Just came home from work to see it was dark and silent. The temperature was at 77 F. I have it set at 79 F. The power in my room where I have the tanks is gone. Its a good thing I came home on time! I connected everything up with 2 long extension cords for now until I get someone to have a look. It could have been a disaster and I could have lost everything. What I learnt from this is don't ever ever overload a socket!!!
