What is the effect of true blues? I think there was a warning about the windex look with too many.

I have 18 nw and 38 rb all at 100% 750mA. I think when I first set it up I thought it was a little bluer than the Phoenix bulb I was running, but I'm used to it now so I can't tell.

True blue are suppose to bring out the orange colors of your corals, but you have to make sure they are on really low. Option 4 is decent, but I was thinking that with option 4 I should have more royal blues, because i'm using XM-L for my whites, at 2800 mA and most people use much less powerful natural whites with a 2:1 ratio to royal blues. So maybe keeping half of my cool whites and only 20 royal blues is a better idea?
