Never pour pool shock into the skimmer, pre-dissolve for use in vinyl liner pools. When broadcasting shock across the surface, be mindful of the wind direction. Brush the pool after shocking, and filter the water for at least 8 hours afterward.
Adding Pool Shock Through Your Skimmer
Combining calcium hypochlorite or dichlor pool shock and chlorine creates a deadly gas. If you have an automatic chlorinator attached to your filter system and you pour the shock into the skimmer, the two chemicals will combine in a very small space.
You can add chlorine in tablets and sticks directly to the skimmer, and they slowly dissolve into the pool water. Liquid chlorine comes in gallon containers. You can apply it by pouring the liquid into the skimmer or directly into the pool water.
The answer to whether you should add borates to the skimmer is yes and no. You should ideally mix at least half of your borates with pool water in a bucket and then pour it around the edges of the pool. What is this? Once that's done, then you can take the remainder of the dose and pour it into the skimmer basket.
Calculate the amount of shock you will need to mix. Refer to the amount indicated on the package of the shock chemical you plan to use. You can add some granular pool shock to your swimming pool directly, but most varieties need to be mixed with water before use.
Measure the dry chemical, pre-dissolve in a bucket, and pour around the perimeter of the pool (never into the skimmer directly). There are a few types of dry, granular chlorine. These are primarily used as a shock, because of how rapidly they dissolve in water.
So, are you looking for ways on how to add liquid chlorine to pool? You can either feed the liquid chlorine through your pool's mechanical chlorinator, or pour the solution directly into the pool. This is preferably done when the sun isn't out so that you achieve the best results.
The general recommendation is to use 1 pound of cal hypo shock for every 10,000 gallons of pool water, and 10 ounces of sodium hypo with around 12.5% chlorine to sanitize your pool. Make sure the pool water is at its normal level.
SKIMMER NOTES: No. Chlorine and shock are not the same thing.
Shock has a more intense chemical strength than the traditional chlorine sanitizers, and it also differs in how you should apply it to your swimming pool. Short answer: No.
Light Green or Teal Pool Water:
In this case, you should double shock your swimming pool water. To double shock, you will need to add 2 pounds for every 10,000 gallons of water. For instance, if you pool is 20,000 gallons, you will add 4 pounds of shock.
Shock-chlorination is an essential and effective method of cleaning the pool. But you need to have the pump circulating the water for this to be effective.
Pour the liquid chlorine into the pool with the jug as close to the water surface as possible in order to prevent splashing. Add the liquid chlorine to the deep end of the pool. After all of the liquid chlorine has been added, brush the walls and floor of the pool.
Do NOT use chlorine granules in a floater or feeder. When you're adding granules, broadcast them evenly over a wide area in the deepest part of the pool – NOT in the skimmer.
Unlike tablets, granules come in a significantly lower concentration which, along with their size, make them easy to dissolve in water. To add chlorine granules to the water, you simply sprinkle them around the surface instead of using a dispenser.
For every person who uses the pool each day, you will require a further 10 grams of chlorine. Example – A 50,000 litre pool will require up to 200 grams of chlorine and if 5 people use the pool a further 50 grams of chlorine is required = total of 250 grams per day.
Running your filter after shocking your pool is a must and is just as important to your pool as shocking it is. Be sure to run your filter for at least 6 hours, but shoot for 24 hours to several days, if your pool is particularly dirty or has algae, to properly circulate the chlorine and clean the water.
Let the pump run for about 6 hours or more and test the water. Don't use the pool right away – wait for the free chlorine levels to drop to 1 – 3 ppm before it is safe to swim.
Run the filtration system
While shocking your pool will help kill any germs any algae, it won't actually get rid of them; for that, you need your filter. So be sure to run your pool filter for at least 24 hours.
If using 6% liquid chlorine bleach, add 5 gallons per 10000 gallons. Add the Shock: With the filter system running, and the pH on the low side, 7.2-7.4, add the chlorine (granular or liquid) slowly to the pool, dispersing it around the pool edge, or broadcasting the pool shock over the surface.
