Broom the entirety of the pool. Run pool filtration for 24 hours (You will need turn your chlorinator off or down depending on make and model). Turn chlorinator back on to a suitable setting. Avoid swimming in the pool after Super Chlorination.
Superchlorination, also known as shocking or chlorine shocking, is the process of adding several times more chlorine to the pool than is normally needed so that the chlorine can "burn" through resistant compounds, chemicals, oils and strong types of algae.
DO NOT SWIM for at least 12 hours after superchlorinating your pool. Make sure to test the water before entering the pool to ensure the chlorine is between 1.0 - 3.0 ppm.
Let the pump run for at least eight hours after shocking, and wait for the chlorine level to fall below 5 ppm before anyone goes in the water.
Brush the pool vigorously, several times after shocking the pool. Do not use a solar blanket until chlorine and pH level are normal. If chlorine level drops to zero within 24 hours, Repeat the shock treatment. Improve filtration with a pool filter cleaner or filter aid like Jack's Filter Fiber.
A pool filter should be run for a minimum of 6 hours after shocking a swimming pool. This is to allow the filter to clean the water and give the shock enough time to fully mix with the pool water. Running the filter after shocking for 24 hours to 7 days is necessary if the pool has a large amount of algae.
Heavy shocking with granular chlorine will generally require 24-48 hours before the chlorine level has dropped to safe swimming levels (below 5 ppm). Lithium and Non-Chlorine shock labels typically allow immediate swimming, but check the package label, to be sure.
When you super-chlorinate your hot tub or pool (used interchangeably with 'super shock'), it needs to be done with chlorine or bromine. It, too, raises the chlorine levels. The difference is that when you super shock a pool, the amount of chlorine you add is nine times that of a shock treatment.
This will give you an idea of how much shock you need. 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.
Here's how it works: Salt is added to the pool, and then pumped through an electrolytic cell where it's converted to chlorine and then pumped back into the pool. The result is a clean, clear, luxuriously soft water that is less work and worry for you – and your wallet.
And how long do you have to wait before you can swim? You should wait one hour per pound of shock product added, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool.
This is why many pool experts recommend that you turn down, or shut off, your saltwater chlorine generator (SWG) while you're shocking your pool. Otherwise, you're running the risk of damaging the salt cell. And that could lead to it not generating enough chlorine after the shocking process finishes.
The ideal time to shock your pool is in the evening after all swimming is complete. In the evening because the sun will not be boiling the chlorine out of your pool, and after everyone is done swimming because shocking is going to bring the chlorine level up to a level that may be irritating to skin and eyes.
INITIAL STARTING DOSAGES :
Maintain chlorine at a minimum of 1.5 ppm and up to 3 ppm. The more swimmers you have and the warmer the water is, can double your pool's chlorine consumption. Add whatever amount of chlorine it takes to maintain a 1.5 ppm chlorine..
The IntelliChlor SCG is designed only to produce chlorine. The IntelliChlor SCG does not monitor or control chlorine levels in the pool or spa water. It is the pool ownerʼs responsibility for monitoring and maintaining free chlorine levels at the APSP recommended range of 2.0 to 4.0 parts per million (ppm).
Using baking soda will not actually lower your pool's chlorine level. If your ph is way too low it may. Prevent corrosion and damage to pool equipment; To raise your ph levels, it can be as simple as adding seven to nine pounds of baking soda to your pool water.
Diluting your pool water by draining and adding fresh water is a great option if you only need to lower your chlorine levels by 1-2 ppm. Remember that you're draining the other chemicals in your pool too, so make sure to do a pool water test when you're done.
Two different chemical agents that can reduce chlorine levels are Sodium Thiosulfate and Pool-Grade Hydrogen Peroxide (specific to pool treatment). Be sure to test your water after using one of these agents as they tend to impact pH, sometimes dramatically.
The size of your pool, the efficiency of your pump and filter, and how dirty your pool is are just some of the factors you need to consider. Nevertheless, most pool cleaning professionals would advise against running a pool pump for more than 8 hours a day.
In the industry it is recognized to have the pool run for 3 hours at a bare minimum up to 24 hours. 24 hours really is overkill but it'll ensure the water is completely mixed with the chemicals.
Pools can immediately turn green after shocking when they have metals like copper in the water. These metals oxidise when exposed to high levels of chlorine which makes the pool water turn green. Adding a metal control product such as Zodiac Metal Remover will help to restore the pool water.
It Should Not Be Done Together
This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM. Only then should you introduce algaecide to get the best results.
While green algae are endemic in salt water pools, they are the easiest to kill. Green algae tend to grow during summers when the temperatures can get high. They float freely in the pool, making the water green. You might even see them growing on the bottom of the pool, on the walls, or in the crevices.
Turn down the salt cell system. If you've reached the recommended chlorine level for your pool, the shock should last several days, so you can turn down your saltwater pool system—also called salt chlorinators or chlorine generators —for a while.
