Im not sure, I turned my carbon off to see if I see a difference in anything. I think its just because of it being a Mariecultured coral. All my other corals that arnt mariecultured look great and are growing really well and coloring up really nice. I have two mariecultured corals one that got the bad tips and the other one is fading color. I am trying to figure out what they both need and I really think that my lighting may just be to much for them. I moved my one that was fading out of as much light and its coloring back up now. We will see. The fact that all my other corals looked so good is was made me think that it has to be something wrong with just these two corals and couldnt be something wrong with the system itself.

Because during the same time my Green slimmer went from brown polyps to bright green and I knew this was a good thing.
