When the pH in a body of water gets high, chlorine becomes ineffective. The effective chlorine in a body of water can be almost totally depleted in a few hours. Also, with the use of chlorine there is a significant increase in irritation of the eyes, ears, and skin. In conclusion, chlorine itself is not doing a satisfactory job in protecting the health of the public.
Ionization uses electronically produced copper and silver ions to purify a body of water.
The copper kills algae and the silver kills bacteria and viruses. The ions do not dissipate like chlorine and, remain very stable. The body of water will stay sanitized days or weeks with the system turned off, and no additional copper or silver ions being added. Copper and silver are not absorbed through the skin. In fact, a glass of EPA approved drinking water could have 5 times as much copper in it as a glass of water that has been processed with ionization.
