Those corals you have aren't very demanding in light, you can always reduce the intensity some, especially since there are no nutrients for it to consume. My experience, too strong lighting with no nutrients = pale / dying corals.
I don't think that's too many changes. Also, I would suggest removing the carbon as well since it strips away a lot of the organics from the water. Keep your current feeding schedule. Also, go get 1 astrea snail. They are amazing at cleaning rocks from algae.
