I’m trying to increase my par in my tank while also considering my custom lid. It just came in today and my lid isn’t quite what I ordered in terms of spacing for my lights (did a change that didn’t flow through so likely won’t fight it). I was originally hoping to add a 3rd XR15 blue in the middle of these lights to increase par for the top rocks I have my SPS on. With the new lid and how it was cut, putting a third one in the middle will have them be a bit closer than planned. That said, will I be better off adding a third XR15 in the middle or selling the ones I have and replacing with XR30s? Will that overlap with a third XR15 boost the par over the top of the two islands with my SPS?
