4 gradesActivated glass mediaAFM® Activated (Glass) Filter Media, supplied in sealed bags. The range is graded by particle size — Grade 0 (0.25 – 0.50 mm), Grade 1 (0.5 – 1.0 mm), Grade 2 (1.0 – 2.0 mm) and Grade 3 (2.0 – 4.0 mm) — so the correct grade can be matched to the filter vessel and the media bed being built.

10 kgTablet saltWater softener salt tablets in a 10 kg bag function by dissolving in a water softener’s brine tank to create a concentrated saline solution used for resin regeneration, which removes hardness minerals like calcium and magnesium from your water.FeaturesIon Exchange Regeneration: As hard water passes through the softener’s resin bed, the beads trap calcium and magnesium ions, trading them for sodium.Recharging the Beads: Over time the resin beads become saturated and lose effectiveness. The salt solution flushes through the system, washing away the accumulated hardness minerals and reloading the resin with fresh sodium ions.Limescale Prevention: By keeping the resin active, the system continuously prevents limescale buildup in household pipes, water heaters and appliances.
