Types of Sanitizers
From the first day you fill your pool, the water must be maintained with a chemical sanitizer, also called a disinfectant. Enough sanitizer must be present in the water to kill bacteria and algae. Properly maintained pools normally do not have odors or cause eye irritation.
In addition, you must balance your pool water to the recommended pH and alkalinity levels and maintain them in the proper range. For chlorine, bromine, and PHMB sanitizers, maintaining the pool water pH between 7.2 and 7.8 and total alkalinity between 60 and 180 parts per million (ppm) will help ensure your sanitizer is effective.
In the pool industry, the generic word “chlorine” normally refers to any sanitizer that releases free available chlorine—also known as hypochlorous acid—when dissolved in water. Chlorine sanitizers are the most commonly used pool sanitizers. Chlorine is also a strong oxidizer.
Cal hypo (Calcium hypochlorite): This sanitizer is a white solid that quickly dissolves in water to produce free available chlorine. Cal hypo is available as a granular product and in various tablet shapes. Cal hypo has the highest chlorine content of all fast dissolving chlorine sanitizers.
Dichlor (Sodium dichloro-s-triazinetriones): This sanitizer is a white granular solid that quickly dissolves in water to produce free available chlorine. Dichlor contains a stabilizer that improves the chlorine stability in pool water that is exposed to sunlight. Dichlor has a minimal effect on pH and total alkalinity:
Sodium hypochlorite (or bleach, sometimes incorrectly called liquid chlorine). This sanitizer is a lightly colored liquid. Sodium hypochlorite has a relatively low chlorine content when compared to solid chlorine sanitizers.
Lithium hypochlorite: This sanitizer is a white granular solid that rapidly dissolves in water to produce free available chlorine.
Trichlor (Trichloro-s-triazinetrione): This sanitizer is a white solid that slowly dissolves in water to produce free available chlorine. Trichlor is most commonly available in various tablet shapes. Trichlor contains a stabilizer that improves the chlorine stability in pool water that is exposed to sunlight. Trichlor has the highest chlorine content of all solid chlorine sanitizers.
In the pool industry, the generic word “bromine” normally refers to any sanitizer that releases free available bromine—also known as hypobromous acid—when dissolved in water. Bromine is also a strong oxidizer.
Bromine Tablets: This sanitizer is a white solid that slowly dissolves in water to produce free available bromine. A chemical feeder is used to conveniently provide a steady addition of bromine to the pool.
Chlorine and bromine can cause a fire if contaminated with combustible organic materials, such as oils, gasoline, and paint thinners. These chemicals can produce toxic gas if contaminated with other materials.
Copper Ionization: Copper ionization was developed in 1967 for the Apollo Space Program to insure safe drinking water and to control scale in cooling systems during space missions. The ECOsmarte System incorporates this same technology. The copper ions created by the ECOsmarte System are safe and essential for humans, plants and animals, but are lethal to bacteria, algae and some viruses. By adding these ions to your pool or spa water, the ECOsmarte System basically kills bacteria, algae and certain viruses and prevents them from growing in the water.
Because both copper ionization and oxidation is natural, there will never be any chemical backwash. Making it safe for the environment to drain and backwash your pool.
Mineral Pac: This system controls bacteria using a combination of minerals and reduced chlorine levels. The end result is softer water that has an added sparkle. With minerals, chlorine use can be cut up to 50%* over standard water treatment programs. This is a very convenient way of reducing chlorine use and hassle.
Salt Systems: Salt Water Chlorine Generating Pool Systems are designed to produce sodium chloride (chlorine) on a daily basis thus purifying your pool/spa water during pool circulation mode. The salt water cell contains electrodes that are charged and utilize electrolysis to convert the salt in the pool water into sodium chloride (chlorine) at nominal amounts every day. These systems are designed to maintain a sodium chloride content of 2,500-3,500 part per million which aides in the balancing of your pool water. This will help achieve water chemistry balance and decrease the need to purchase or store vast amounts of chemicals.
