As far as spectrum goes, a mixture is what most people use with the ultimate goal being achieving the desired spectrum for growth and color. Blue=more color and less growth. White=more growth and more browns and greens with less coloration in corals.

Ok let's go with that which of those 3 bulbs are blue which is more white n lastly the other one must b for fresh water plant. Which is which do u know?
