I don't use any secondary optics on a 24" deep tank with the LEDs 8" off the water. Plenty of light for SPS all the way to the bottom. Tried 80 deg optics for the first 2 months, but didn't like the effect, too much top down light and not enough light from the sides. Corals look much better without the optics, and no "hot spots" or disco.
