Thank you Hopinso for sharing.
After all the different possibilities what is good or bad, I am still using the prill beads to make water. There does not seem to be one right solution.
I was making the prill water with bought distilled water here in Florida, since I take minerals anyhow. But I realized that my dog I don't give minerals, so to-day I got spring water for him and then used the prill beads with that. He drank it right away so it looks he liked it.
