P.S. Thanks for the article! ^,^
I solved this problem by having a room light on its own timer. My tank lights come on at 10am, and although the shades are mainly closed, the room is light; you could easily read a book in the ambient light. In the evening the lights go off at 6pm, and in summer there is still daylight of course, but during the several months of winter, darknes outside. So I have a wall light on a timer, it comes on at 5.55pm and goes off at 6.55pm. I tested this by sitting quietly in the room when the tanks lights went off, and there was no discernable shock by any of the fish in their tanks. But before I did this, I would hear fish crashing into the end walls and jumping against the cover glass in all the tanks when the tank light went out in a dark room. B.
