Stabilised Chlorine Granules & Pool Water Sanitation

chlorine granules swimming pool house

Swimming pool water must be sanitised to ensure the safety of bathers when using the pool.  Chlorine is the most popular form of sanitation.  It is highly effective for destroying algae and potential germs. Bromine is an alternative particularly if you have sensitive skin.

Chlorine Granules is the most widely-used chemical for swimming pool sanitisation, through ease of use it has gained popularity. It kills bacteria by undergoing a simple chemical reaction where chlorine breaks down into hypochlorous acid and hypochlorite ions, which then oxidise bacteria until they are neutralised or destroyed.

Advantages of Chlorine Sanitation

  • Chlorine has a long shelf-life and can, therefore, be stored for long periods of time.
  • It is available to consumers in many different forms. Most common is liquid or chlorine granules.
  • Not only does it neutralise contaminants when it is first added to swimming pool water, but it also continues to neutralise long afterwards.

Disadvantages of Chlorine Sanitation

  • Chlorine are chloramines and trihalomethanes, which cause skin and eye irritation to swimmers.

How to use chlorine granules for the best pool sanitation

Your pool is constantly being polluted by the environment including pollen and leaves. Also, swimmers using sun creams and lotions.  So although your pool may look sparkling and clean in reality, it is not.  Your filter will remove a lot of these debris, but you will still need to sanitise the water on a regular basis to keep it clean. 

Recommended levels for your pool

Minimum:                    1ppm – 7.2 pH

Recommended:          2ppm – 7.4 pH

Maximum:                   3ppm – 7.6 pH

Based on a pool containing 1000 litres of water to adjust your pool water, you need to add 2 grams of chlorine to increase the free chlorine.  To reduce your pH, you must add 10grams per day of pH reducer until it lowers to 7.4.  If you need to increase your pH, you must add 10grams per day of pH increaser until your reading is 7.4 for pH.

Having got your pool chemical range in the correct parameters, you now need to maintain your algaecide levels for crystal clear water.  Add per 1000 litres of water initial dose 25ml, and then every two weeks afterwards add 2mls.

Caution never in any circumstances must you ever mix pool chemicals use a separate container for each of the chemicals and add to the water separately.  Always add granules to the water never water to the granules.                             

 After adding chemicals to your pool water, it is advisable to wait at least 30minutes before using your pool, before adding chemicals to your pool make sure your circulation pump is running. Never add chemicals to the water while the pool is in use.  Should you shock dose your pool with chlorine,  you must wait till the residual of chlorine has dropped to 5ppm or below before using again.

To test your pool, you can use either test strips or tablets.  Test strips are the easiest way to check the levels of your pool water as they will test for both pH and chlorine levels.  Tablets are a reliable way of testing your water; they are very accurate. Having tested your water, you will need to adjust your water accordingly.  It is a very good idea to keep a record of all your readings so you have something to refer back to.  Should you have problems, your local dealer should be able to test your water if you take in a pool sample.

Chlorine Granules How To Use

Chlorine Granules are a very effective way of disinfecting your swimming pool as this will destroy bacteria in your pool. Chlorine Granules How To Use? Is best dissolved in a bucket of warm water and distributed around the pool. It is important that it is completely dissolved before adding to the pool or it can bleach the liner and make it go brittle over a period of time.

How to use chlorine granules

Useful Information: Having a bucket with a lip makes it easier to add the chlorine granules.  Alternatively you can use chlorine tablets which come in measured doses, making it easier to administer the correct dose. The disadvantage is they take longer to dissolve in the pool water.  Another alternative is liquid chlorine which is much faster acting and can be either put in the skimmer or poured around the pool the pool while running the pump.

  3. Mix the chlorine granules into the warm water until completely dissolved using a plastic or wooden stirrer.
  4. Turn on the pimp so that the chlorine disperses around the pool rather than settling on the base of the pool. Pour the diluted chlorine around the pool taking care not to spill any on your clothes, as it will bleach them and cause them to go into holes.
  5. Let the pump circulate the chlorine around the pool for one to hours until fully dispersed before swimming in the pool. Test the pool chemical level before using to make sure that it is safe to swim in. If you add chlorine at the end of use for the day still circulate the pump for one to two hours.  Then leave overnight.  Then test the water the next day before use to make sure that it is safe to swim in.

 

Water quality is affected by the effect of pH, which is affected by the alkalinity. pH levels that are too high or too low can cause cloudy water and make scaly deposits. Water balancing chemicals have a crucial part to play as they prevent damage to your pool and poor sanitation.

Balancing water in your pool means to bring the water balance to the correct level for safe bathing.

  • When you have finished adding the chlorine, replace the skimmer cover correctly. Then continue to run the pump for approximately another one to two hours before testing to see if the chlorine is at the correct level for swimming.

Chemicals should always be diluted in a bucket of water stir until dissolved then add to swimming pool. Never add to pool without diluting as it will cause damage to the liner including colour loss and making it brittle. It will also have damaging effects on other types of pool finishes.
