Hey there, I agree woth rhythmicfire, I have the same setup as a prop tank. I keep some of my lords off to the side on the bottom, and the sps on top a little higher, directly under the lights. Certain aquacultured lords and micros maintain their vibrant colors better under 20K. With all that wattage per gallon, just watch your temp and your ph, depending on how long you run those lights. I only run 4-5 hours per day. I watch my parameters because I do heavy feedings for my lords. Along with frequent water changes. Hope this helps. Al
