I am starting this thread for all AI user to share their AI light setting, as i believe it would make it easily and useful for reefer to refer to, and adjust according to their tank need reducing the time to setup their lighting. Below is my setting for Hydra 52 , Hydra White : 65 % Blue : 80 % RB: 80% DB : 80 % Red: 30 % Green : 30% Violet : 30 % UV : 20 % Light is abut 18" above water level, and tank height is 18" . Ramp time 4 hour ( 11.30 - 3.30 pm ). Mostly SPS corals.
