About This
- 💧WHAT IS SILIPHOS: Siliphos (also known as Slow Phos) is a slow-dissolving, food-grade polyphosphate used for treating potable water. Ideal for scale and corrosion control. Each bead is approximately 3/4" (0.75") in diameter.
- 💧POWERFUL SCALE PREVENTION: Prevents scale buildup from calcium and magnesium in hard water. Helps protect pipes, faucets, water heaters, and home appliances for longer-lasting performance.
- 💧CORROSION & RUST PROTECTION: Forms a thin protective layer on metal surfaces, helping prevent corrosion caused by acidic or hard water. Ideal for extending the life of boilers, plumbing fixtures, and heating systems.
- 💧NOTE: Due to the nature of the material, Siliphos balls may crack into shards during shipping. Shards can still be used as normal, and may allow you to squeeze a bit more material into a filter housing.
- 💙 TRUSTED EXPERTISE: With over 15 years in the water filtration industry, Max Water has delivered effective solutions and exceptional customer service to millions of families. Choose Max Water for reliable, high-quality filtration solutions.
