http://redearslider.com/shell_conditions.html"It is normal if there is a small amount of algae on the shell, but it is not a necessary condition. It is usually seen on wild turtles or RES kept in outdoor ponds. Most captive RES that are kept indoors have little or none. Algae should be easy to remove if the area is wiped down with a towel or gently scrubbed with a toothbrush and water."
Are you sure it's algae? Take some pictures and let's be sure. If it's something else like fungi it would require a different treatment.
Out of every 100 men, ten shouldn't even be there. Eighty are just targets. Nine are the real fighters and we are lucky to have them, for they make the battle. Oh, but one, one is a warrior, and he will bring the others back. -Heraclitus of Ephesus
