I have PERFECT Lighting (For these SPS frags) BRS TV Video

Well some luck.

BRS TV just put out a investigative video on Ideal Lighting for Corals (Specifically some SPS details)

What is Absolutely Great is their Setup is almost exactly the same as my tank.

Two MH LIghts (250W), and Two T5's (Coral Plus and Blue Plus).
I do have the LED but it's more for accent/off peak our viewing.

What they show with their measurements is almost exactly the same as when I did my Par readings in my tank (shown in post above).

Their recommended PAR Target is around 250-350 PAR. Their measurements show some higher spots nearer the Lights and at the bottom where more reflection on glass occurs. (I didn't know about the lower spots having more reflection near the glass. Reflection Angle makes this happens)

I am running my lights at around 14" for more spread. Their experiement was done at 6 (to not spill light over tank, but I can spill for better even distribution, since my Lights over tank are in Sump Room, behind wall)".

Plus I am currently running my lights at 150W, but can go as high as 250W in the future with a flip of a dial on the Switchable ballast.

So things look very promising, and I need to stay on the low side, till these corals acclimatize and grow up.
