View Full Version : Frag tank lighting

10-09-2011, 06:22 PM
I'm taking am old 46 bow front I have and creating a frag tank out of it until I get my big tank. I'm going to use a frag tray and put it a few inches below the surface. Will one Par 38 LED (18 watts) six inches above be sufficient for a one sqft area for most higher light corals?

6 inches above the water or above the frag tray?

Above the frag tray - trying to maximize light from small bulb setup.
