Can you help with this turtle shell? - white border blogspot

I saved a Red Turtle, one of my friends. It was a turtle in a container of 5 cm is too small, 10-20 liters, and the animal is even worse for the wear. Due to take my stupid MTS (Multi-tank syndrome) I have decided that this small and see if I can go out and rehab. Probably, I took a different animal:)

The turtle is eating well 36in. (the anachris ghost shrimp and a dozen day 3) and know when I'm not. Whenever I go means the tank room projection of the surface. It's funny, red, and everything I even surprised him swinging his claws into his thinking. Then, of course, healthy, with the exception of the shell of these subjects.

In any case, the dish is equally hard with the color in different forms in the bowl. The plastron seems unaffected. It is to be green, I think it is an alga of any kind, do not worry. There are black in color, most of which came with a soft toothbrush and seems to come from the borders of the shields. More worrisome is the color white looks like hard water stains.

Any ideas on diagnosis? I am sure that is the sign next boot it, but could not take care of 6 months, there's something I do in the meantime?
