I have 2 Nicrew 150w lights with the programmable controller. The lights ramp on at 7 am to 70 % blues at 10 am and then ramp down and a 5% minimum white spectrum so i can enjoy the tank in the evening. When the whites come on some corals , like my torch especially begin to withdraw.
Is it because the lights are nicrew amazon lights? Is this a normal reaction for the corals? I cant use any less white spectrum because 5% is the lowest.
