POLYTRANS Spa Hot Tub Filter Mineral Sanitizer Stick for Spas and Hot Tubs(2-Sanitizers)

How does PolyTrans Spa Mineral Sanitizer Stick work?  The silver, copper (express & professional) and zinc (spa sticks) metals are attached to a ceramic substrate; due to its large surface area we are able to maximise surface exposure to the water. As water flows through the PolyTrans Spa Mineral Sanitizer, silver and copper particles are dissolved into the pool water. Silver has a natural (Saturation point). This means that the silver can only reach a certain level in the pool water. The cartridge will then stop releasing silver into the pool. Dissolved silver concentrations can only rise to 0.01 to 0.06ppm which has no risk of staining. Dissolved oxygen in the water attaches to bacteria. The dissolved oxygen laden with silver damages or destroys the bacteria. Copper is not stored in reserve in the PolyTrans Spa Mineral Sanitizer cartridge but is all released on start up. Copper levels cannot exceed the staining threshold of 0.2ppm, due to the fact that the cartridge only contains enough copper to raise the pool water to 0.02 to 0.06ppm.
