@SeaDweller - If memory serves, you're rocking 4 x Orphek 48" fixtures. I'm thinking of getting away from the shadowing that seems to be inherent in my two Hydra 26HDs (over a Reefer 250 with a footprint of 35.5" x 20" x 21"). I have frags that are only receiving light on half of their structures and it's beginning to irritate me. I should have purchased Hydra 52HDs initially given my intended application. Do you think an Atlantik V4 Compact (Gen 2) will provide enough spread and avoid shadowing long-term for mature colonies given my tank's footprint? Or would I need the non-compact model?
The compact dimensions are: 24.21" x 9.37" x 2.11"
The non-compact dimensions are: 13.58" x 9.37" x 2.11"
@Chaswood79 had the right idea with the 52HDs.
