Magnetic Water Treatment K&J Magnetics Strong

Magnetic Water Treatment directs water to pass through a strong magnetic field. By placing two strong neodymium magnets on either side of the incoming pipe, all the water passes through a strong, uniform magnetic field. Magnetic water treatment does not remove any calcium from the water. Technically, it is still just as hard as before it passed
