6 Top-rated Pool Flocs

Iit’s the middle of summer, and you’ve planned a big pool party. But the pool is cloudy! No one’s going to swim in that! That's where pool flocculant comes in!

Pool flocculant is a chemical that when added to water clumps together particles sending them to the bottom of the pool where they can then be vacuumed.

It works by clumping together particles suspended in the pool water, which are too small to be caught in the filter. By clumping them together, it makes them big enough to fall out of suspension to the bottom of the pool. They can then be removed by manual vacuuming.

It’s ideal for sand and diatomaceous earth (DE) filters. Because those filters normally have multiport valves that include a “Waste” setting, it’s easy to bypass the filter when removing the clumped particles and the flocculant.
