When I had colonies before I sold them due to moving, it didn’t matter. Grew the same up high or down low. High par colony (about 400) was a neonish pink/red and the lower par (about 175-200) was a deep red. Looking at the 2, you would not thing the same acro, except structure. The light intensity just excites specific zoo and that is where the color shift comes from.
Excellent! thanks again
