I am running one hydra 26hd...I have my blues at about 75% white at about 35 and others around 10-15...

I am about to add a second 26hd for more even coverage.. would I need to lower the totals for both lights by a percentage? Or run acclimation mode or what?

I did. I run mine at 18-20k. With one I ran it at 100%. When I got the second 26HD, I started at 40% and did a weekly increase of 5%. At 70% thinga went bad. My anemone closed up and one ofor my sps corals tips turned white, still is. I'm sitting at 60% and will probably stay there.

Yea I think I'm gonna turn em down at least 25% or so... and see how that does... the light will move directly over some corals as where it now is off to the side
