When Should I Shock My Pool
The best time of day to shock your pool is in the evening after sunset so that the suns UV rays will not evaporate the shock from the water and will allow the shock to oxidize the water for a longer length of time.; Youll want to choose a time when your swimmers are finished and out of the pool for the day because you dont want anyone in the pool during this time.
Make sure to use protection when handling shock such as eyewear and gloves. Prepare the shock by following the manufacturers recommendations. Once you shock the pool run the filtration for 24 hours. Make sure to recheck your pool chemistry the next day and balance accordingly.
What Is Shocking A Pool And Why Should You Do It
Shocking a pool, also known as pool chlorination, is adding chlorine in swimming pool water to sanitize itgetting rid of chloramine , contaminants, bacteria, preventing algae, ammonia, and other living organisms from thriving in your pool.
Chlorinating a swimming pool is a very important and necessary part of pool maintenance.
Every pool owner should at least understand how to do it, how frequently, what amount of chlorine to add, and which chlorine shock to use in a pool.
Moreover, the cornerstone of keeping free chlorine active all the time is keeping it in proper balance with cyanuric acid.
The higher the cyanuric acid level in your water, the more your free chlorine will be ineffective, and the more chlorine you will use in your pool.
Confirm on Trouble Free Pool’s Chlorine/CYA Chart to know the correct amount of chlorine to add at a given level of cyanuric acid.
By regularly adding chlorine shock to your water, you completely avoid the hassle of SLAMing your pool to clear algae and ammonia.
To have a trouble-free pool throughout the summer, I always recommend the use of non-stabilized chlorine known as sodium hypochlorite with a 12.5% chlorine concentration for pool sanitization.
You can also use sodium hypochlorite with a 10% chlorine concentration, but not a regular household bleach that comes with low chlorine concentration of 8% and below.
Got My Shock But How Much Do I Need
As with any cleaning chemical, the amount of pool shock you use depends on the volume of your pool. Generally, the magic number is one pound per 10,000 gallons. This is especially easy to measure out when you buy pool shock conveniently packaged in one pound bags. Why not make your life easier?
Not sure how many gallons of water your pool contains? Simply multiply the length, width, and depth of your pool in feet, and then multiply that figure by 7.5 to convert the number to gallons. Its a quick calculation anyone can doeven if you never exactly aced geometry. And if you think better in formulas, that would be:
x x x 7.5 =
When opening your pool for the season, you should use double the amount of shock to really clear out any bacteria, algae, and who-knows-what thats built up in your water throughout the winter. That would be two pounds of pool shock per 10,000 gallons of water.

How To Shock The Pool
The moral of the story is that you have to test your pool to know when to shock. Shocking monthly or even weekly is overkill in many cases.
Why Shocking Is Important
Unfortunately for pool owners, you cant just fill up a pool with water and expect it to always be clean.
Due to outside influences, the state of pool water is constantly changing, becoming increasingly grimy with each passing second.
Even though pools have a constant sanitizing agent in the water, over time it breaks down and slowly becomes less effective. At this point you need to add more of it if you want the pool to remain clean.
The idea behind pool shocking is to quickly raise the free chlorine level in the pool, killing off bacteria, algae growth, chloramines, and other pathogens in the water. This can be done using either chlorinated or non-chlorine pool shock.
Chlorinated pool shock is the most common. It gives the pool a massive dose of chlorine, killing everything in its path.
Non-chlorine pool shock is an oxidizer that attacks organic contaminants in the water. By focusing strictly on those, it frees up the free chlorine in the pool so it can be more effective in sanitizing the water.

How Long After Shocking A Pool Can You Swim
After being shocked, your pool will temporarily have high levels of free chlorine . Swimming in highly chlorinated water can cause skin irritation and other harmful effects. The CDC recommends that pool owners maintain free chlorine levelsbetween 1-3 parts per million for safe swimming.
Depending on the treatment you used, it may take anywhere from an hour to 24 hours for your swimming pools FC levels to return to a safe range.

How Often Should You Shock Your Pool
The frequency of pool shocking isnt set in stone, and it really only needs to be done when your water starts going haywire.;
Some things youll be able to visually see , but most water pollutants will be invisible.
There are some pool owners who like to shock once a week to keep the water its cleanest, while others will do it on a 3-week or monthly cycle.;
Shocking frequency also depends on how much use the pool is getting, and what kind of weather its being subjected to.; Heavy rainfall and storms can disrupt the pool waters chemical makeup by introducing backyard debris and air pollutants like dust and pollen spores into the water.;
Likewise, an increase in the number of people using the pool will bring in more organic bacteria, resulting in a chlorine level decrease. If you have a pool party, youll most likely have to shock the pool once its over.
Youll also want to apply shock treatment when opening the pool, and closing it down for the season.
On opening, after youve balanced its pH level, shocking will sanitize and oxidize the pool, restoring its clear water. On closing, pool shock is used as a disinfectant to prepare the pool for the winter months.
Also of note, if you were wondering, you cant overshock a pool. The worst that will happen is the water has an abundance of chlorine for a few hours. Once the sun comes out, it will quickly destroy the chlorine and bring the pool back to a level that is safe for swimmers.

Add Shock To The Pool
If using dissolved granular shock, make your way around the perimeter of the pool and slowly pour the solution into the water. What this allows for is the power of the return jets to circulate it quickly. If using liquid chlorine, pour it around the perimeter of the deep end of the pool, and close to the surface to avoid it splashing up.
In some cases with granular shock, you may end up with undissolved granules on the walls of the pool, or at the waterline. Take out a pool brush and remove them pronto. These little granular buggers can damage the liner/finish if left to their own devices.
Also, make sure your pump and filter are running all night. This ensures the pool shock will be fully distributed in the water to destroy all contaminants.

What About For My Hot Tub Do I Need To Shock That Too
Congratulations, youre one of the fortunate among us with a hot tub. But calcium hypochlorite is not for you.

In detail, the process of pool shocking means adding chlorine or non-chlorine shock to your pool in order to raise the free chlorine level. The goal is to raise free chlorine levels to a point that destroys unwanted contaminants, such as algae, chloramines, and bacteria.;
A common term for using a pool shock to destroy combined chlorine is called breakpoint chlorination. Usually, reaching breakpoint chlorination will require adding 10 times the amount of combined chlorine present in parts per million .;
