Kent Liquid Reactor

I am probably a dummy, but upon reading that article, I really did not ascertain if that product is useful. The writer said he would tell us later in the article, but to me he did not really do so. I gleaned from the article that it might be useful to put some aragonite in the pail one uses for topup water, but really nothing more. Could someone tell me if I misread it?
