Calcium blocks nourish the water in the turtle tank, dissolving slowly and keeping the water clean and odour-free. This mineral is essential for the turtle, as a lack of calcium can lead to the premature death of the animal.

How do we know if our tortoise is suffering from a calcium deficiency?
When calcium levels are low, we can notice it in the yellowish tone of its shell and in the loss of its usual hardness. You will also notice it in their mood: lack of activity and apathetic attitude.
