Great product which slowly lets loose over time. Was lovely to see it break down and the turtle was happy with it in there. The little stream of air bubbles when placed in were a great experience too. Review: Turtle calcium block. - Thanks.

It is so bad for your turtle. Buy Cuttle Bone instead it leaves no cloud and is 100% healthy. Please don't buy this it's so toxic Nd can make your turtle seriously ill **Q: Do this go into the filter or tank?** A: Tank **Q: Is this suitable for tortoises ?** A: This isn't meant for tortoises and is meant for slow release in water for aquatic turtles/terrapins. My terrapin bit it to pieces quickly and probably consumed some too without harm. I would think a tortoise, especially a large one, would quickly destroy it too, and perhaps consume too much in one go. Zoo Med do a larger tortoise block which I have found excellent for my tortoises. It is bigger, more substantial, and therefore takes the tortoise much longer to consume the calcium and wear down its beak in the process. My Horsfield tortoise actually mounts the block so you could say its environment enrichment at the same time!! ## Customer Reviews ### ⭐⭐⭐⭐⭐ It breaks down slowly *by M***E on 15 May 2025* A little calcium turtle to put in a turtle tank to help our turtles shell.
