Depending on the form of calcium used in the block, they may not be the best thing to give your turtle (some forms of calcium are more readily assimilated than others). And the turtle-shaped blocks often contain sulfa, which is a drug; continued use of a block containing sulfa may result in your turtle's developing a resistance to it (the sulfa).
I'd try the cuttlebone and flavor it as was suggested. Some of my turtles aren't interested in it once it sinks, but it's still good. You'll just have to try it and see. If you dry it out and put it back in the water, it will float, but once it's been waterlogged it won't float as long as it initially did.
