Plastic container filled with polyphosphate crystals for anti-scale water conditioning providing prevention form scale deposit and calcareous incrustation and protection from corrosion for water heaters, washing machines, pipes.


SLOPHOS products are a form of slowly soluble polyphosphate available in small, glassy beads. As their name implies, SLOW PHOS products dissolve at a controlled concentration to prevent scale formation and corrosion.


NSF Certified

SLOW PHOS has been Certified under ANSI/NSF Standard 42 Drinking Water Treatment Units – Aesthetic Effects, and ANSI/NSF Standard 60 Drinking Water Treatment Chemicals – Health Effects, for use in potable water systems at concentrations up to 10 ppm. Dissolution rate: 90-180 days.

Scale Prevention

Sequesters hardness, inhibiting precipitation and form-ation of deposits.

Corrosion Inhibition

Forms a protective coating on metal surfaces, providing corrosion protection against acidity, alkalinity, and many other mineral salts which may lead to the "rusting out" of water system pipes and equipment.

Iron Control

Sequesters dissolved iron up to 10 ppm and prevent the iron from precipitating, staining, discoloring, and distasteful flavor.
