Black Pro-Calcium Terrarium Sand - 10 lbs - Natural Substrate for Reptile Habitats & Aquariums, Silica-Free & Mineral-Rich

The Reptile Sciences Terrarium Sand is a 10-pound bag of black sand designed for use in terrariums. It is advertised as having calcium and being suitable for reptiles. However, customer feedback suggests that this sand may not be the best choice for certain reptiles and other animals. Some customers have reported that the color of the sand is not as advertised. One customer mixed the black sand with other colors and found that it turned out to be a chocolate brown color instead of black. Another customer mentioned that the sand has a nice pearly color when mixed with other colors. While some customers have been satisfied with the sand and found it easy to clean, others have found it problematic. The sand is described as having bigger rocks than desired, which makes it difficult to sift and clean. Additionally, it tends to stick to everything and does not hold heat well. One customer mentioned using the sand in a fresh water fish tank, but it is worth noting that another customer advised against using it in a fish tank due to the extra vitamins in the sand that could disrupt the balance of the tank. Overall, the Reptile Sciences Terrarium Sand has mixed reviews. While some customers have had positive experiences with the product, others have found it to be problematic in terms of color, cleaning, and suitability for certain animals.
