Beautiful Todd. Let me ask you if you noticed a difference when you added the Violets? Growth? colors? I personally think that 400-430 is very important
I also believe fully after a lot of research just how important the Violet spectrum is to both growth and Coral color (both fluoresced and reflected) and did indeed notice a positive change. Growth is/was hard to tell as many of my colonies are so large and grow so fast, the Rose Milli alone probably has 250-300 growth inches per month and I regularly frag the Birdsnest colonies otherwise get to be Basketball size. What information I did not add above is that from spreading out the emitters I get a very even PAR reading throughout most of the tank comparable to T5 consistency, 250-350 PAR for the most part for the entire upper half and 150-175 on bottom half even partially under tabling Acro's. As compared to most commercial fixtures I don't end up with 'Hot Spots' or 'shaded' areas.
Cheers, Todd
