Details:

Mitras 6100HV running in High Efficiency mode with max output at 80% (brightness set to 70% in Light composer)
Initial PAR numbers:

~280 at water surface (9.5" from lights)
~150 9" down from water surface
~80 20" down from water surface in somewhat shade

Mitras 6100HV running in High Efficiency mode with max output at 100% (brightness set to 95% in Light composer)

~480 at water surface
~250 9" down from water surface
~120 20" down from water surface in somewhat shade
~150 on bottom of tank

So the important question is do you think bringing up the average PAR values by 50% is a bad idea? Seems a little drastic to me. I am thinking maybe dial them back to a 25% increase and see how things react and then go back to the 95% brightness. Suggestions, opinions, etc?

I went ahead and dropped total brightness down to 82%. That put the PAR numbers all ~25-30% higher than original. I will see what response that gets and then go up from there hopefully. The whole reason i want to go up is from the reading I have been doing on PAR values around some of the SPS I'd like to keep.

Things were looking pretty good before. Every time I tweak my mitras I bleach coral so I don't change it anymore. Good luck

How much would you tweak the brightness and still see bleaching? I wonder if I went too much even raising the PAR 25%?

[Scythanith]

Now I am second guessing myself.... I am going to go dial it down some more...
