Proposed Coral Layout - Feedback

[crabgrass]

Hi -

Over next several months, I am trying to plan how to re-stock corals after i push back a GHA infestation. Does the layout below make sense? Note that the powerhead in the photo below slid down, and would be at the top 1/3 of the tank.

What lights are you running?

Currently have a single Prime HD. this is a 20g Drop-off (Mid-level is 10.5 inches, Max Depth is 16 inches from top of tank)

I was planning on picking up a Hydra 26 HD for better coverage - however open to suggestions
