I have had this coral for some time. He has grown quite well over the last 6 months. I ensure he has high water flow and all parameters in my tank are normal. I actually havent tested magnesium yet but i will here soon. He is fading at the bottom in a way that is showing a slight blue to grayish color at the base of it nearest the rock he is mounted to. Is he dying? Please help.
Thanks
Paul
