Flocking the pool is essentially the introduction of a certain chemical compound that binds with floating debris in pool water. This debris literally clouds up the water and can be anything from algae to dirt or any number of minute particles that are not captured by the filtering system.

What does flock do to a swimming pool?

What is Flocculant? Flocculant, or pool floc as it’s sometimes called, is a chemical that you add to your pool when other methods of clearing it up aren’t working. The flocculants clump together floating particles in the water that are too small and light to sink to the bottom to be vacuumed up.

Will floc clear a cloudy pool?

Pool floc binds particles (and dead algae) that are making your water cloudy together and sinks to the bottom of your pool so you can easily vacuum out the cloudy mess.
