i have no lights on till 3pm - then a single t5 white coral tube kicks in, then at 3.30 the blue one kicks in, then at 4, a second white kicks in, then at 5, a second blue 'in total 4 t5 lights blue and white', then at 6.30 the first white goes off, then a blue at 7, then a white at 7.15, then the final blue at 10.30.
the blue kicks in and fades out so not to spook the fish - looks lovely too!
