I have seen that as well. Esp interested in battlecorals. He was why I got the breeders to begin with. This is leading me to think I should focus on chemistry vs lighting. I just wanted to get some insight.
What are your settings currently?
Do you have the v2?
Mine are at 100% white, blue, light blue, violet and 10% red and green.
I took out the lenses for maximum spread as they are only 4" above the water.
They grow SPS!
