SLOW PHOS Slow Dissolving Phosphate Beads (5 Lb.) - Anti-Scale Filter Media

This is a 5-pound bag of SLOW PHOS slow-dissolving phosphate beads.

They're used in water filtration systems as a replacement media to fight scale buildup.

These beads slowly release food-grade polyphosphate into the water, which sequesters minerals like calcium and magnesium, preventing them from forming hard scale in pipes, water heaters, and boilers.

They're made in the USA.

If you have a system that uses this type of phosphate media, this bulk bag is a great way to refill it.

Model number is SLOWPHOS-5.

Keep your water system running clean and scale-free., description_length: 651
