I think it is a bit more complicated. My knowledge is admittedly limited on the subject of color spectrum since I’ve always run halides, but my understanding is that blue light may be sufficient or even the preferred spectrum, but white light is still providing PAR. So turning down the whites may be fine if the blues are cranked up to compensate, but just turning down the whites alone would mean decreased PAR, and potentially lead to issues.He said he only turned down whites, corals don't usually care about that right?
