Good for you for removing the sulfa. The sulfa blocks are not good for the turtles. If the water is clean, you don't need sulfa (it's an antibiotic). If you use sulfa when it's not needed, the germs will develop a resistance and then, when the turtle is sick and really needs sulfa, it won't work.
By the way, there's another type of turtle block that looks similar to the sulfa blocks but it really is just calcium. These blocks are very effective, however. If you want to give your turtle calcium, go with a cuttlebone.
