Shock Chlorination for swimming pool and spa

Why shock chlorinate your pool?

Shock treatments are typically used to get rid of extra germs and any contamination in the pool after extended pool use, contamination occurrences, or to treat water with visible algae. Frequent shocks are the greatest approach to maintain a clear and clean poo. Using a solution that has between 65 and 70 percent hypochloride will help eliminate any bacteria and algae that may be present. Shock treated pool is not to be used for 24 hours after the process. While some uses this method to maintain a clean pool, some others may use it after a problem is in site, such as green pool, chlorine smell, or just when the pool gets very dirty. Although shocking the pool will clear the difficulty, it is always best to carry out these steps even before the issue occurs. The ideal free chlorine present in a pool water should be 1-3 PPM(parts per million). This can be determined using a tester. It is Important to test your pool regularly for its pH and Alkalinity level, as the alteration in these chemicals can easily lead to pool contamination.

Types of chlorine:

Stabilized chlorine:  has chemical links CYA (cyan uric Acid) that prevent it from degrading under sunshine. Allowing one  to modify the chlorine content less frequently.

Unstabilized chlorine: Unstabilized chlorine is just chemical chlorine with no additives. The common additive in stabilized chlorine, cyan uric acid, is not present in unstabilized chlorine. This means that if the pool gets exposed to direct sunlight, the chlorine inside will react to the sunlight and break down.


Forms of Chlorine for Shocking your pool:

  1. Liquid Chlorine

The most popular and most accessible form of chlorine for balancing your pool is liquid chlorine, sometimes known as bleach. The pH of your pool can be raised and balanced quickly with pH plus. Applying liquid chlorine is as easy as pouring some liquid in front of your pool's jets and letting it circulate around the pool. Most of the time, there is a management procedure for utilising liquid chlorine to balance your pool; alternatively, you can just pour the liquid around the margins with great caution.

  1. Chlorine Tablets

The tablets normally contain roughly 90% chlorine for balancing your pool, they are excellent for those searching for a lower maintenance approach to sanitation. Many pool owners choose the pills because they work well for long-term pool health maintenance. The best time to take the tablets is after the first shock has passed. Chlorine tablets are the favored option of many experts for those wishing to maintain an already balanced pool. The skimmer, chlorine floaters, or an automatic chlorine dispenser can all be employed to utilize them.

  1. Granulated Chlorine:

It is required to pre-dissolve the granulated chlorine before introducing it to the pool for best results, once done the concoction can be poured around the pool.

How Often should you shock your pool?

Below are the 7 scenarios for a chlorine shock treatment for your pool

  1. Use shock whenever the free chlorine level is off, or you detect chlorine odor. Use a tester to determine the level.
  2. When opening the pool after a break
  3. Weekly shocks for maintenance
  4. Shock the pool after excessive use, multiple swimmers, a party
  5. After a heavy rain, as the chemicals in water are bound to change.
  6. Shock when it's sunny or hot
  7. It is also best to shock your pool while shutting it close, this ensures that the pool is ready to use, when opened at a later time

Ensure checking the alkalinity and the pH level of the water before treating your pool with any chemicals for optimum results. It is best to have the chlorine shock carried out at night, as the sun will burn out the chlorine in the water.
