It means you have Hardwater, i had the same problem with my yellow belly when i first got him and your local pet store should sell RO Water which is softwater, if not just simply buy a RO System and fill your tank with the softwater, he's now 2 and a half years old with a perfect shell.
He might have shell rot, If that's the problem you should go to your vet, But if your turtle has been out of water for a while it is probley just dryed out. Then you might want to put it in some water for a while , yellowbelly sliders must have water in their habitat. Hope this helped!
