| The question as it appears in the 02/05 edition of Specs & Techs from GlobalSpec: Tomas purchased a new swimming pool for his family. Unfortunately, after their first dip in the pool, they discovered their daughter, Juanita, was allergic to chlorine additions. Tomas tried using bromine and several other chemicals, but little Juanita also developed a rash from exposure to these harsh chemicals. She was unaffected by very low levels of the chemicals, but these would only clarify and adjust pH while leaving the algae and parasites alive. How can Tomas kill the algae and parasites and keep the pool clean without giving Juanita a rash? (Update: Feb 12, 8:54 AM EST) And the Answer is... Tomas should purchase a chemical free UV sterilization system for the pool. The UV water sterilization system should allow them to kill the algae and parasites and keep their pool clean with only residual levels of chlorination and pH control chemicals. Tomas will not get a rash because high levels of harsh chemicals are not required. Another benefit is Tomas will never have to add chemicals to the pool again. Industrially, UV Light Systems are useful for sterilization, curing, analysis, identification and sunlight simulation. -- Disclaimer - We are not selling these things nor are we in contact with the manufacturers.
