Marine animals absolutely need lots of blue (actinic) but an
excess is of no use at all for fresh water plants. Mind you
I haven't looked to see if they are of any use for fish, snails
or other animals in freshwater aquaria - they might be.

As long as you stick to conventional fluorescents, the so-called
colour temperature of the lamp makes very little difference to
the way plants grow - picking what you want to look at is fine
as far as I can tell.
