i'm using a light revolving unit now which rotates the lights in a circular pattern over my cube tank. The corners are not getting enough light so I'm in the process of changing it over to a light rail unit that will move the lights back and forth. There is a unit with a 30 second delay at each end of the rail to increase the light times at both ends of the rail.
