Can you use masonry sand under your in ground pool?

Yes, you can use masonry sand under an in-ground pool, as it provides a stable base for the pool structure. However, it's important to ensure that the sand is well-graded and free of debris to prevent shifting or settling over time. Additionally, some pool installers recommend using a specifically designed pool base material, such as pool sand or crushed stone, for optimal drainage and support. Always consult with a professional for the best practices for your specific pool installation.
