I currently have 2 XR15 pro on my 4x2x2 tank. This has been fine to get the tank started and support LPS and some easy SPS. But as the tank matures I will want to step up to some more demanding SPS.
So my question is: Should I simply add a third XR15 or should I start over with two XR30? Since I will have to buy new lids if adding another XR15, but can sell my current lights if going to thr XR30, there is a marginal difference in cost.
To me the three XR15 will provide the most even coverage, with lights 10” from the edge and another in the middle.
Is there anything I should be thinking about here? What would you do and why?
