Hello. I ordered the IM Nuvo 150 ext and it is finally coming in. For those of you who don't know, it's a very deep tank. The dimensions are 47.3” x 35.4” x 19.7”. Now I'm pretty sure I'm set on radions (was between that or neptunes) but I'm not sure what is the right amount of light. Long term, I'm wanting a mixed reef with some acros and other sps. What should I get? 2 XR30 running long ways front to back? Or 4 XR15 running the width of it? Or go a different direction altogether? I'm just spending the money now but want to do it right. Please help. Thank you
