Shocking is also known as super chlorination. This is a way to keep your pool water safe and clean by adding 3-5 times more chlorine than usual or other chemical disinfectants to the water to dramatically raise chlorine levels in a short period of time. This will help remove ineffective chlorine, kill bacteria and life in the pool, and increase the availability of effective chlorine. Shocking your pool is an important regular maintenance step that every pool owner should be familiar with.

Steps

Method 1 of 3: Timing to Shock

1. 1 Shock the pool regularly. "Regularly" will depend on the number of swimmers using the pool and the temperature of the pool water. The best indicator is monitoring the results of chlorine tests for home use; When the test results show that the combination of available chlorine and free available chlorine is below the recommended ranges, it is time to shock the pool.
   • Pool experts recommend shocking a pool at least once a month. If the water is warm (for example, for spa pools), it is recommended to shock at least twice a month. However, some pool experts recommend shocking pools once a week, or more often if the pool is heavily used, after heavy rain or during extended periods of hot, sunny weather.
2. 2 Shock after sunset. This will prevent chlorine or other chemicals from being exposed to the sun's ultraviolet rays and ensure that most chemicals are available to shock the pool.

Method 2 of 3: Shocking Preliminary Preparation

1. 1 Dissolve shocking pool chemicals. This must be done before adding them to the pool. All forms of shock pool chemicals are granular and should dissolve relatively quickly.
   • Fill a 20 liter bucket with pool water.
   • Slowly add the granular pool shock to the bucket of water.
   • Never do not add water to the chemical; always add chemicals to water.
2. 2 Stir the contents of the bucket well. Stir the water for one minute or more to dissolve shocking pool chemicals.

Method 3 of 3: Adding Shocking Chemicals to the Pool

1. 1 Turn on the filtration system, gradually pour in a bucket of dissolved "shock" directly in front of the return line fit. You will see that the water is flowing into the pool with a stream coming from the return line.
   • Pour slowly enough so that all the water in the bucket enters the pool and does not end up at the bottom of the pool. Pouring slowly is also very important to prevent splashing onto your skin, clothing, and any surfaces that might hurt or stain, depending on where the splash goes.
   • Pour as close to the surface of the water as possible.
2. 2 Refill with water. When you pour the solution, and when you have about 1/4 of the dissolved shock water left in the bucket, refill the bucket with water.
   • Stir the contents of the bucket again for one minute or more to dissolve the remaining shock granules at the bottom of the bucket that did not dissolve the first time.
   • Continue pouring until you have used up all the contents of the bucket.
   • If undissolved granules reach the bottom of the pool, mix them with a pool cleaner.
3. 3 Test the water before returning it to the pool. Swimming in water with a high chlorine content is very dangerous. Wait until the water reading is 3 ppm or less.

Tips

• If your pool has vinyl liner, you cannot allow undissolved pool shock to settle to the floor because it can bleach or stain the pool liner.
• Shocking chemicals can also be applied with a floating chemical dispenser or mechanical dispenser rather than manually shocking. Mechanical feeding devices require very precise proportions and only chemicals from the manufacturer are suitable.
• Check the pH range before shocking. It must be within normal limits before being shocked, otherwise the extra chlorine can oxidize the copper parts in the pool. If this happens, black spots will appear on the surface of the water.
• Keep in mind that it is best to add shocking chemicals in small amounts in various locations throughout the pool, rather than dumping in large quantities in the hope that they are evenly distributed.

Warnings

• Always add chemicals to water. Not add water to chemicals.
• The manufacturers of shocking pool products suggest that you wear safety glasses and other safety equipment to prevent injury. Follow the manufacturer's instructions on the packaging.
