There was an interesting article on HC-110 called the unofficial HC-110 guide:(posted 8508 days ago)http://www.covingtoninnovations.com/hc110/
In one point in reading about the compsoed components of the solution, there is a chemical called pentetic acid which is a chelating agent in removing most of the physical minerals that may be in regular water. I'm wondering if anyone knows how much of an amount this chemical works in doing this type of job? This is an interesting article to read.
