I am only running 4, 48 Inch, 10K T5's in the middle of the tank (tank is 56 inches long) On each end I have acentic 240 NO flourecent lighting that came with the tank LFS says my lighting is equal to over 600 watts, same lighting he uses in his DT. Not sure what the purpleish tree is in my tank, lfs had no idea. I have 3 leathers, 2 are finger and the other is a toadstool, green and yellow polops, several shrooms and some pulsing xenia. I had to move everything down because they were getting to much light, and are doing great now towards the bottom. Everything has grown alot in just a month. I am sure i can get some lps and they will do fine, once i build my rock up higher.
