You want something that is chemically neutral like silica sand. If it is sandstone or limestone sand it will probably be basic which you don't want. Look up the MSDS (Material Safety Data Sheet) on the manufacturer's website or ask the store for one for the product - it should say what the material is and maybe the pH.
Instead of asking for opinions, find out for yourself. Just put a spoonful of the sand into a cup of vinegar. If it fizzes don't use it. If there's no reaction, it's safe.
i got sand from petco thats a pretty good consistency, not too small, not too big... It's for aquariums and says it wont change the water chemistry so (im assuming) it could only be silica
The acid test can be misleading as some of the materials used in the grinding process (if any) can react with acids. That's why you should rinse construction sand and such. However since it claims to be "washed" it may not be necessary.
Im always trying to find that stuff when I go to home depot. I never can and the idiots who work there never know what the **** I'm talking about when I ask about silica sand or pool filter sand. I know exactly where it should be on the shelf too but its never there or anywhere
Is there more than one store in your town? Now most of the HD's carry it where I am, but for a time only one or two stores had it. Might want to check another local store. Or maybe ask if they could order you a bag or two. Stores rarely wish to turn away paying customers.
