That does sound pretty white. I'm currently using
B+,B+,B+,P+ LED: blues/royal blues, C+,B+,B+,B+
My old set up had 4 ati true actinic I liked the pop but i replaced it with B+ because i was afraid of not having enough PAR. I forgot the exact readings when i tested the par but with the replaced Blue plus i had higher par spread in more places.
My LED are at 45% and i'm keeping it there because of some reports that higher intensity might bleach the corals.
