I picked up 3 50 lb bags of the #20 mesh, what color is yours ? mine is a light brown
Mine is from canada and on the bags it says it is a processed silica sand and that it is dried & sterilized. it also says low dust.
Any pool filter sand should be fine.. just be sure to rinse, rinse and rinse it some more.
How do you rinse sand?
This pool filter sand says it is sterilized and has low dust, but i will rinse it big time anyway. I never heard of baking the sand until the above post mentioned it.
