If you want me to point out all the misinformation in your original post i will.
After reading your #1, If i was an uninformed reefer with a 96w PC over my fuge, and little macro growth, i'd think.... Crap, i have too much light. I need to get a low light system. When, in fact, the 96W would probably be far superior to a 20w PC.
And by FAR, my favorite sentence in your original post........
"Usually lighter color comes from rapid growth or too intense lighting"
lol, this is basically what i said. Intense lighting causes rapid growth. Rapid growing chaeto is light green.
Think about that sentence of yours for a bit....
