120w LED settings

[TommyP]

Hey RC,

I have a 75g tank.

About 1-1.5yrs ago I purchased my LEDs from e-bay. They are the 120W Dimmable LEDs. aka Taotronics or Evergrows.

They have so many different ones now with reds and greens etc but I'm not fancy on that. Mine are just blue/white.

I just was curious to know what is the best setting (%) to have the blues and whites?

Right now I have recently turned the whites all the way down (10%) and blues are at 50%.

Let me know your opinions & advice.
