Floatron Solar Ionization Floatron is the original portable and floating water purifier ~ combining solar electric power generation with ionization, resulting in the only solar ionizer manufactured today. The Floatron converts sunlight into electricity by the advanced technology photovoltaic panel, which energizes a specially alloyed mineral electrode below the waterline, causing the release of mineral ions into the surrounding water. Ionized (mineralized) water naturally and efficiently controls microorganism growth in your pool, while completely harmless to people. The Floatron is totally safe and nontoxic, with absolutely no danger of electrical shock. Water remains clear and stable for extended periods because the minerals do not evaporate. Unlike chlorine, hot summer conditions do not degrade the performance of the mineral ions; in fact, the hotter the weather, the better it works! Some pool contaminants such as dust, sunscreen, suntan lotion, body fluids, etc. are not affected by the mineral ions. An accumulation of these contaminants will tend to cloud the water. Therefore, a small amount of chlorine or other oxidizer is necessary to disolve them and maintain crystal clear conditions. However, with the Floatron, only small amounts of an oxidizer are necessary. Typically, Floatron users find an 80% reduction in chlorine usage. The Floatron is built to last! Made in the USA, it has no moving parts and is constructed with space-age polymers which are weather, sunlight, water and chemical resistant. The solar panel incorporates the most efficient photovoltaic cells available. The mineral electrode is alloyed from a special combination of ultra pure elemental metals. It costs virtually nothing to power and operate the Floatron. Assembly is simple and the only part which requires replacement is the sacrificial mineral electrode which will last approximately 1 - 3 swimming seasons. The electrode takes only a minute to change and replacement cost is minimal.
