Free available chlorine kills bacteria in pool water fast, protecting swimmers from infection. Chlorine is available in many forms: granules, liquid, tablets, or via automatic chlorinators. There are other important variations as well.

Inorganic vs Organic Pool Sanitizer
Inorganic type chlorine comes in granules (calcium hypochlorite) and liquid bleach (sodium hypochlorite). The granules do not dissolve completely, leaving a residue that can cloud water and form scale. This could lead to expensive repairs, or worse, replacements of pool equipment.
Inorganic, unstabilized chlorine also raises pH (acid/alkaline balance) dramatically, affecting chlorine’s killing power and requires frequent dosing of acid to adjust the pH level to within acceptable pH parameters.
Non-stabilized chlorines are also vulnerable to sunlight, breaking down quickly and requiring frequent dosing and specific dosage timing, Needless to say, in the climatic conditions in various parts of the USA this is hardly any solution!
Stabilized Chlorine – The Effective Solution
Stabilized chlorine performs continuously, 24 hours a day, come rain or shine. Look out for the sun-protected symbol on all chlorines which protects against chlorine-evaporating ultraviolet rays.
Thanks to this improvement, stabilized chlorine can destroy bacteria continuously, maintaining water quality and making swimming pleasurable and healthy at all times.
You can also dose your pool at any time of the day or night – another pool sanitizer method of ensuring you hassle-free pool maintenance.
Three Easy Manual Chlorinating Methods
Pool sanitizer chemicals are now catering to every pool owner’s needs. Chlorine has been tailor-made to suit your particular maintenance routine. You now have a choice of dosing every alternate day with granular chlorine, weekly with the pill treatment, and even monthly with a new floating chlorine feeder.
1. Stabilized Granular Chlorine
Under normal conditions, a cupful of granular chlorine should be sprinkled directly into the weir every second day, depending on demand. More or less frequent dosing will be determined by bathing load and weather conditions.
2. The Pill
Two stabilized chlorine pills need to be dropped into the attractive floating chlorinator once a week and fortnightly testing will determine whether booster pills need to be added.
3. Month Mate
Some chemical manufacturers have a monthly tablet, this is the ideal method to chlorinate your pool while you’re away on vacation. It also caters to those of us who are lazy pool owners!
Once a month is all you need! The monthly dispenser is dropped into the pool after the required notches (depending on the size of your pool) have been cut and chlorine is released into the water at a steady, continuous rate to sanitize your pool
Floc and Super Chlorinate Swimmer Wastes and Chloramines
Soluble swimmer wastes like perspiration, suntan lotions, urine, hair sprays, and so on will build up after heavy pool use, rainstorms, and hot spells, resulting in cloudy water and promoting algae growth. This is why it’s essential to use an effective pool sanitizer.
Offensive chlorine smells may also result although this is not a result of excessive chlorine, rather too little chlorine. What happens is that chlorine combines with the nitrogen of swimmer wastes to form chloramines – odorous, irritating compounds. Use a pool shock to oxidize or “burn out” all nitrogenous compounds and chloramines.
So why is chlorine such a great pool sanitizer?
Swimming pool sanitation is the process of ensuring healthy conditions in swimming pools. Proper sanitation is needed to maintain the visual clarity of water and to prevent the transmission of infectious waterborne diseases.
Two distinct and separate methods are employed in the sanitation of a swimming pool. The filtration system removes organic waste on a daily basis by using the sieve baskets inside the skimmer and circulation pump and the sand unit with a backwash facility for easy removal of organic waste from the water circulation. Disinfection – normally in the form of hypochlorous acid (HClO) – kills infectious microorganisms. Alongside these two distinct measures within the pool owner’s jurisdiction, swimmer hygiene and cleanliness helps reduce organic waste build-up.An extract from https://en.wikipedia.org/wiki/Swimming_pool_sanitation
