What is the difference between a clarifier and a flocculent? A clarifier is designed to be used with a filter system, so particles coagulate in the filter. A flocculent is NOT to be used with the filtration system as the filter may clog. Flocculants are formulated to drop particles to the bottom of the pool, so they can be vacuumed away.
