In The Swim Super Floc Out – Drop the Gunk, Ditch the Cloud, Dive Into Clear Water – 1 QuartBrand: In The Swim Features: In The Swim Super Floc Out swiftly clears cloudy pool water, working in hours rather than days like clarifiers. Our pool flocculant promotes coagulation, clumping tiny particles together, which then sink to the bottom for easy vacuuming. Flocculant doesn't work with cartridge filters unless you have custom plumbing for filter bypass during vacuuming. Removes silt, organic matter like leaves or insects, oils, and lotions.
