I would put a 30 every foot. Don't underestimate how bad the spread is, even with a diffuser. It is a shame that you cannot raise them up any more. 10 15s staggered might get the job done pretty well since you can spread them out more than a 30.
Dr. Joshi used 10 Radions to replace 3 MH that were on his tank - you really need a lot if you are going to be hardcore into acropora... not as many for MBP&S. |

Yeah If I thought things out more I would have gone with the 15s. But I got 3 of the 30s so I already committed to them so...
How should I run them front to back or left to right. A while ago I watched the brs video on them and was thinking 6 of them front to back ��. We’ll see |

It's not spread that's the problem with radions (or with any of the mostly point source lights) it's shading as the SPS grows. Three 30s would be more than sufficient for a 6' tank initially, but as the SPS colonies grow, the point source nature means you'll get shading issues.
I really don't get why folks run these lights perpendicular to the long axis of the tank ..... unless your goal is to actually grow algae on the front panel. I have four over my 8' 450 that is 3' wide/deep and I orient them parallel to the long axis. I just don't keep any SPS on the sand for the first 6". I have opined in the past that buying 15s rather than 30s is preferred. Of course, this didn't occur to me until AFTER I had bought the 30s
