Hi All, first nano, 36 gallon bow, 30×12x20 I'm using the viparspectra 165, the tank was just started, no livestock at all yet. I have done a lot of research on the lighting settings, this forum being the most help But one question- i see people using odd percentages if blues/whites, like 30%/3%...... in ky settings I'm only seeing 10% intervals. Am I misunderstanding something? Thanks Ryan
