Here’s a pic of how my sump is set up. I've got a macro cage underneath a self ballasted 45 watt pc light (equivalent to 150 watt incandescent). It’s very easy to create and cheap to set up if you have room in your sump. The cage is simply a modified plastic storage bin I bought from Fred’s (like a Dollar General) and the light and reflector came from Ace Hardware. I’m going to add some chaeto in the next couple of days.
God bless,
