Pool Info: Catalytic Sanitation
Nature 2 Mineral Sanitation
Celebrating over 20 years in the industry, Nature2 purifiers have become one of the greatest success stories, rivaled only by Polaris perhaps. Now owned by Zodiac, (who also owns Polaris) - Nature 2 has expanded their line of mineral purifiers for pools and spas, and also coupled the Nature2 technology of Cationic Sanitation with Salt Chlorine Generators.
Early use of metal ions for pool purification were electric devices, with plates of dissimilar metals, usually copper and silver. Applying electricity to these plates causes the charged metal ions to jump off towards an opposite charged plate, where it is swept away by the water current in the pipe. Use of such systems like Caribbean Clear do have sanitizing properties, but misuse by homeowners can lead to a staining problem. The cells also required maintenance, and the overall system was costly to install.
