You'll bleach everything in the tank if you go 100%. I have 4 Sol Blues on my 120 and they are incredible and extremely powerful so you will have to start very low and work your way up. I'm only running mine at 40% (tamk is 26"s deep) and find it to be plenty of light.
On another note, Apogee PAR meters are not measuring the blue spectrum of the light correctly (read an email correspondence on another forum from Apogee to the member) from the blue led's so the resulting PAR reading is actually much higher then indicated on their meter so proceed with caution as blue light penetrates the water better than white light so bleaching is still very possible if your settings are more towards the blue side.
What brand light fixtures are we talking about I want to take a look at them
It is correct a correct statement that the blue LEDs reach deeper into the tank than the whites. The whites usually aren't high enough intensity and balancing them out with the blue is a challenge for us reefers.
I found the AI Sols to be too blue for me.
PUR is a better way to talk about LEDs when it comes to coral propagation. Unfortunately very few manufacturers talk about this. It is what is important to our corals. Lots of light put out PAR but if there is very little PUR then our corals won't do well.
