Radion xr15 suggested intensity help

[Coralfornialiving]

My buddy gots a 42 gallon 29 1/2" x 18× 18 . He just recently got the xr15 and was asking me what intensity should be fine for it to prosper. He has corals in there that had kessil 360 on it. Any advice or recommendation for the level it should be set at.

With my xr30 gen 1's I started at 40%, using the acclimation mode went to 65%. With the tank being shallow, I would start at 35% and go to 55% over 3-4 weeks.
So, somewhere in that area is my suggestion.
