I have a 55G long 48X15X15. Only trying to light up 36X15X15 area. I have 2 Kessil 350W. Most of the corals I am concerned about are Acan, Zoas and Palys. Z and P are mostly located 1"-5" from the sand bed. Acans are mostly on the sand bed. My question is % on blues and whites? Time period they are on for? How high from the water? Thank you.
