Yes, chlorine is used with Pristine Blue.
Chlorine helps in:
• Killing bacteria and algae that can cause cloudy water and bad odors
• Breaking down organic materials such as sweat, suntan lotion and body oils to prevent them from forming into scum lines or foamy layers on the surface of your pool's water
• Balancing pH levels to make sure the water remains safe for swimming.
It also helps reduce chloramines which are formed by combining chlorine with other contaminants present in the pool water. This ensures healthy swimming conditions in your pool all season long!
