Help identifying powders for pool

[CarlD]

I would not use them unless I was 100% certain of what they are. Powders could be DE, Baking Soda, Soda Ash, Borax, etc. Wet they could burn your hand.

[PoolDoc]

1. Does it dissolve?

2. How much does 1 cup weigh?

3. Assuming it dissolves, what is the pH of 1/4 tsp added to 1 cup of water?

4. Are you SURE it was a pool chemical?

5. Buy a box of borax, baking soda, and soda ash . . . and compare.


Be careful about throwing it away, till you know more.
