I am running Hydra 52's with all blue spectrums at 100 and white at 70. I have a lot of sps coral down low and a Maxima clam in the sand bed so need to maintain 300 par in the sand. I have some acros that are starting to fade in the areas exposed to the light. Specifically the picture of the "joe the coral" shows polyp extension on the areas somewhat shaded. There is no polyp extension in the areas directly exposed to the light. I have been contemplating cutting back the leds by half and suppmenting t5's instead. Would that help this problem?
