How do water clarifiers such as Leslie’s Ultra Bright work?
In simple terms, they work on the principles of opposites attract and size matters. Much of the dirt and other contaminants that enter the pool are too small to be filtered out by the filter medium (sand in the sand filter, cartridge, D.E.). When the clarifier is added to the pool, it combines with the contaminant and creates particles large enough either to be caught by the filter medium or to settle to the bottom of the pool and be vacuumed out.
