Hi Alex:
Thank you for your prompt response. I have been looking at the XR30W G3 Pro at my LFS, and even had them demonstrate one in the same type of tank (empty) I have. The spread with the stock optics appeared to look adequate, but I, too, was thinking of this model with the wide angle lens. So you believe the wide optic lens would still provide adequate par for sand dwelling LPS even towards the edges? I currently run 6 39W T5's and 3 ReefBrite LED strips.
Thank you again.
