I agree. The most natural looking tanks to me were actinic/MH combos. However, a VERY close second is T5/LED with the blue being handled by the T5 and the LED more of a daylight setting.
By daylight settings do you mean mostly whites/green/red and little to no blue/UV atall? I never really played with my LEDs all that much and still don't so alot of the spectrum blending is still outside my ballpark so to speak.
