Pictured above is my 6ft tank with Two Black Boxes sitting on an aluminum rail. I MANUALLY slide the lights along the rail thruout the day so the light hits my coral at different angles.

Is there a solution to mechanically pull these lights sloooooowly down the rail over the course of a day?

I think some kind of cable and winch system.....pulling like 2inches per hour.

IDEAS????

(Tell ya what.... if someone developed an auto-mechanical dolly sliding rail system for Black Boxes and sold it commercially.... they'd make a small fortune)

I looked into something like that a few years ago. I found a number of contenders used in greenhouses. Couldn't find one that was slow enough though so never did ultimately do it.

I played with the idea of using a rail that is normally used to create time-lapse.

It won't go from one side to another over a whole day. It will shuffle back and forth with a delay at each end
