Spa clarifiers

A clarifier groups micro-particles (oil, dust, cosmetics) too fine to be retained by the filter, into larger clusters that the cartridge can capture. The result: clearer water, reduced odors and more efficient filtration.

Cloudy/slightly turbid water despite OK parameters (pH 7.2–7.8, alkalinity 100–120 ppm, disinfectant in target).

After a long swim, rain or the addition of products that have stirred up impurities.

In support of shock treatment (after the shock, when the disinfectant has returned to the range).

Before a water change to help capture suspended dirt.

Yes, especially if your spa clouds easily (cosmetics, high traffic). In small weekly doses, the clarifier clumps micro-particles so that the filter cartridge can retain them more easily: the filtration works better, clogs less quickly, and the water stays clearer. Otherwise, use it as needed
