With my briggs shell? I have had her a few months now and her shell looks so odd. The white part was like that when I got her. She actually had a large crack around the edge of the shell when I got her. Now the rest that's grown in looks different. I have hard water with high Ph, I feed calcium foods and tums here and there. She acts normal and eats normal. Just want to make sure I'm not doing something wrong. When i took these pictures they came out really dark. She's a blue brigg and is a little larger than a quarter in diameter.
