What are borates and why do you want them in your pool?

I have never heard that you want them in your pool,Nor have I ever had anyone want to add any, Although Borate or Borax (Na2B4O2(H2O)10) is a low-toxicity mineral with insecticidal, fungicidal, and herbicidal properties.But I would not suggest putting them in your pool. People do want them in their pools. Please see http://www.troublefreepool.com/so-you-want-to-add-borates-to-your-pool-why-and-how-t4921.html?hilit=BORATES
