Level above water

[JMorris271]

I'm setting my lights above the hypothetical water level and have them set at 12 inches now. Coral is in the future. Is 12 inches a good starting point?
Thanks

LEDs, halides, T5?

Radion XR30 ranges from warranty-mandated 9" [avoiding splash] to 13" depending on how much depth your tank has. Greater height = greater spread. Your manual might have a specific number.
