I was looking at my grafted monti today and I was wondering if there’s anyway to change or help persuade growth of different colors. You can see that a lot of my new growth is just red.
From what I've seen with grafted corals, one or the other will take over the color over time. I wouldn't mess with parameters for colors. I think maybe changing flow could change growth pattern, again I wouldn't mess with it, unless slowly. Also to not affect your other corals..
