Both pool clarifiers and pool flocculants are used to prevent the pool from being cloudy. Pool clarifier combines tiny particles into small clumps so they can be removed by the pool filter. Effective yet time-consuming, may take days before it clears the pool water. Pool Flocculant (Pool Floc) combines debris into large clumps that sink to the bottom of the pool so they can be removed manually with a pool vacuum. Faster, but needs some extra work. Aquaneo stocks both pool clarifiers and pool flocculants at affordable prices.
