Yes, chlorine raises ORP (oxidation-reduction potential).
ORP is a measure of how good or bad the water quality is.
Chlorine helps improve water quality by raising the ORP level and killing off harmful bacteria and other microorganisms:
• Chlorine disinfects drinking water
• Chlorine kills disease-causing microbes in swimming pools
• Chlorine oxidizes organic compounds to make them less harmful to aquatic life.
By increasing the oxidation power of water, chlorine helps to raise ORP levels and improve overall water quality for humans and animals alike.
