I read somewhere, cant remember where, that coral reaches a photo-inhibition period, where they have absorbed all their daily needs of light, after a span of 4-6 hours. So doing it this way, the coral has a 6 hour period of light and a 6 hour period of rest, twice a day. Effectively doubling the growth capacity...in theory. But seriously so far- puffiest, happiest, most PE showing SPS i've ever had in my 10 years of reefing.
Yup! thats correct. The morning "Bright White" is all levels at 100% so they are actually getting full spectrum, UV, Violet, RB, Blue, Red, Green, White. Then at night they are getting 100% UV, Violet, RB, Blue. So far so good!Interesting. So you’re doing 6hrs of bright “white” in the am, 6hr rest, and then 6 hrs of blues, 6 hr rest each day. Definitely interested to see how things progress for you.
