Thanks for the comments. My not sure what your talking about with the charcoal but I don't run that in my tank.
I had problems with my TS always shifting around blocking a different coral everyday...but those days are over becuase I has plenty of room now in the 90G.
I also have a green TS that is about 1/4 the size of my big one....it's growing fast though and I'm starting to think about how big it will get.:grinyes:
The thing that I love about my TS is that it has a different shape to it everyday. I would highly suggest getting one Grins becuase of their beauty.
