Floc for making your pool water crystal clear

Flocculant or also called flocculant ensures that invisible dirt particles stick together to form larger particles that are stopped by the sand filter.

What types of pool flocculant are there?

Coagulation - flocculation

How does coagulation (flocculation) work?

When flocculating impurities in swimming pool water, aluminum-based flocculants are added. This can be in powder, stockings, liquid or tablets.

With powder and liquid flake product you get flakes in the pool itself. You must let these flakes settle to the bottom. You can then vacuum very carefully, with the 6-way tap in the "sewage" position. This way you will suddenly get rid of the impurities. If your 6-way tap is set to filter, you will quickly get through and the flakes will return to the pool.

SIMPLER is it with tablets or stockings like Flovil, Flovil Shock or Superfloc cartridges. With flake tablets and cartridges or pads you get flakes on the filter. Afterwards you only have to backwash the sand filter and the dirt is gone. A much simpler way to make your swimming pool water clear again. Backwash after about 2 days.
