The only sand that can be safely used from Home Depot is what used to be called
"Southdown" now called
Yardright\Oldcastle, it is argonite beach sand, and is same stuff LFS's sell for much more $$$ --- unfortunately it is not carried by most of the Home Depot outlets. You might be lucky. You could always request a special order.

Comments:
YardRight Tropical Play Sand is an aragonite sand. It is not mined and does not contain silica dust like many playsands do. Many playsands are made from crushed rock which is mined and filled with impurities that should not be in any crabitat.
Many playsands contain crystalline silica, also known as quartz. Exposure to crystalline silica dust can cause lung diseases such as silicosis. Crystalline silica is a colorless mineral, also called quartz. It is an ingredient in sand and flint, which are used in making glass, cement, and concrete.
While the playsand you find in ToysRUs and other places is a lot less expensive this is one case where quality of a product far outweighs the cost.
