I've been trying to find information about providing cuttlefish bones for aquatic turtles without much luck, so maybe you guys can help!

When I placed piece in with my slider, a few hours later it was all broken up into dust floating around in the water. I didn't know if you needed to prepare it a certain way, or if it might mean she's calcium deprived. (All other behavior is normal and she appears healthy)

Thanks for any help solving the mystery!
