Recomended light for corals? 14k 18k 20k?

[TimaT]

I have a Radion LED light fixture.

recently added 2 corals. (coral tree and trumpet coral) been 2weeks they seem fine. will add more.

switched from 20k light to 14k light 2monh ago and my rocks (PURPLE coralline algae) bleached

Should i continue using 14k lighting? switch to 18k or go back to 20k?

whats better for corals?

14k will give faster growth IMO but you can run 20k if you like the look better.
