what are the difference in the two types of bulbs 460nm actinic and a 420nm actinic
I have a 30gal with one 96watt 50/50 don't know what the actinic is 460 or 420
and a dual 130watt with a 1000K and a actinic both bulbs don't say what they are but they don't have the dark blue look and
my tank looks washed out it doesn't have the nice cool glow.
im looking to just swap my 96watt 50/50 out to help gain a little more blue and latter swap the actinic out in the dual with one
that is a liitle better.
