Diy automatic moonlight dimmer?

[Cory]

My reefkeeper elite has the moonlight controller which dims to 0 and runs the moonlights via actual phases of the moon. This is considered critical to breeding coral. If you can't get the DIY to work, perhaps check it out. It isn't too expensive.

Thanks for the tip. But diy is so much more rewarding.
