Hello! I have been researching leopard geckos for a wile now because I plan on getting one in the near future, but I have a few questions on supplements. I know that you provide a dish with pure calcium at all times, but when it comes to dusting food with calcium, do you use pure calcium or calcium with D3? Also, if you provide calcium with D3 on the food, do the vitamins need to contain D3? Here are the items I have been looking at Pure calcium: Amazon.com : Zoo Med Calcium Without Vitamin D3 Reptile Food, 3-Ounce : Pet Supplements And Vitamins : Pet Supplies Calcium with D3: Amazon.com : Zoo Med Calcium With Vitamin D3 Reptile Food, 3-Ounce : Pet Nutritional Supplements : Pet Supplies Vitamins: Amazon.com : Zoo Med Reptivite, with Vitamin D3, 2-Ounce : Pet Supplements And Vitamins : Pet Supplies Any suggestions or help would be awesome!
