So just bought a D-D 1500 and wondering if I need another light. I currently have 2 redsea 90s and plan to be only LPS and softies. The tanks is 5ft x 2ft x 2ft. I read optimal PAR spread per light is 60cm leaving me 1ft short however wondering if I am not doing SPS if I need “optimum” and could do with 1/2 x ft either side of the tank outside of optimum.
