Description Siliphos Water Crystal Balls are a highly efficient and economical water treatment media sold per kilogram (Kg). The Siliphos crystal balls act as a powerful anti-scale and corrosion inhibitor. They work to condition hard water, preventing the damaging effects of mineral deposits (limescale) and rust within your plumbing. These food-grade polyphosphate spheres are essential for protecting all water-using appliances and systems, from borehole to municipal water. Features : Anti−Scale Protection: Siliphos crystal balls prevent scale build-up and corrosion in your water pipes, boilers, heaters, and geysers. Cost Savings: The crystals save you expensive repairs or even replacement of your water pipes, boilers, heaters, and geysers. Energy Efficiency: Without scale build-up on your heating elements, it will save you money on your electricity bills by allowing appliances to run optimally. Refillable System: The crystals are designed to be easily placed in refillable housing or dedicated dispensers. Convenient Purchase: Sold per Kg, allowing you to purchase the exact quantity you need for your system. What does it do: Siliphos water crystal balls is a water conditioner that turns hard water into soft water (by sequestering/conditioning the minerals) and in doing that prevents scale build−up and corrosion in your water pipes. They introduce minute concentrations of polyphosphates into the water, which “sequester” Calcium and Magnesium to stop crystallization, while also forming a protective film on metal surfaces to inhibit rust. Good to know: Dosage: The crystals slowly dissolve over time as water flows over them, requiring periodic top-ups. Application: Ideal for protecting hot water systems like geysers and boilers where scale formation is most rapid. Safety: Siliphos is food–grade and safe for use in potable water systems Specifications: Category Scale Inhibitor  Water Treatment Media Active Compound  Sodium Hexametaphosphate / Polyphosphate-Silicate Form  Crystal Balls / Spheres Purity Food Grade (Safe for Potable Water) Purchase Unit  Per Kilogram (Kg) Warranty No (Consumable Media) Installation Used in Refillable Filter Housing/Dispenser Maintenance: Refill as Needed: The media needs to be replaced (topped up) when the balls in the cartridge or housing are approximately 1/3 dissolved.
