What is the siliphos ball and how does it work

What is the siliphos ball
Siliphos balls are a slow-released chemical agent made from food-grade sodium polyphosphate and calcium oxide smelted under high temperature (1200°C-1700°C). They are used as an economical product to prevent water systems from limescale and corrosion. Siliphos filter is a water treatment media filter housing that holds spheres of sodium polyphosphate. It is used to prevent rust and other corrosive substances from adsorbing on the metal surface and prevents scale formation in water. Siliphos spheres can be inserted into the center core of carbon block or sediment filters or dispensed through a separate filter housing installed in the water line

How does Siliphos work?
Siliphos works by releasing low levels of polyphosphates into the water which interfere with crystal growth, as well as by forming a protective layer of Iron-Calcium-Phosphates along the inner surfaces of pipes, water tanks, elements etc. which deters the deposition and formation of scale. Siliphos acts as a sequestering agent, coating the inside of pipes and making a thin protective layer on metal surfaces to prevent scaling, corrosion and brown or red water. Siliphos does not alter the taste of the water. It dissolves slowly into the water and acts by preventing the adhesion of minerals to metallic surfaces.
