Which Is The Best Chlorine Shock Sodium Hypochlorite Vs Calcium Hypochlorite
There are two common types of chlorine shockssodium hypochlorite and calcium hypochlorite and each is used for a different purpose. Apart from these two, there are also other types of special pool shocks including:
- potassium peroxymonosulphate
- lithium hypochlorite
- dichloroisocyanuric acid
However, all these special shocks, including calcium hypochlorite, are not recommended for regular pool sanitization. This is because their continued use introduces other compounds in your pool water, including calcium, pH, and cyanuric acid, leading to increased levels of these chemicals in your water.
This article is mainly about two common shocks: sodium hypochlorite for daily chlorination and calcium hypochlorite for fighting algae during algae breakout.
The type of pool shock to use in your pool will depend on what you need to achieve, which may include clearing cloudy water, killing germs/bacteria, or fighting pool algae.
How Long After Adding Liquid Chlorine Can You Swim
This usually not less than 8 hours for shock treatments done with chlorine. To gain entrance into the swimming pool to swim again, you will have to wait until the amount of time recommended on the packages instructions is reached.
You are advised not to enter the swimming pool until the chlorine levels have gone below 3 ppm.
Performing Chlorine Shock Treatment
If you want to enjoy your swimming pool for the first time or start up the pool again after the winter, you have to get the chlorine content up to the right level. N.B.: Before you do this, it is best to first check the pH and chlorine values.
If the chlorine value is 0, it is best to carry out chlorine shock treatment.
What is a chlorine shock?
A chlorine shock is the adding of an extra dose of chlorine to the swimming pool to get the chlorine content back to the right level.
When should you carry out chlorine shock treatment?
- When using a swimming pool for the very first time
- After the winter period
- After a holiday period in which the water quality has not been checked
- After a busy weekend of swimming with a lot of people in the pool.
The chlorine level in the swimming pool drops during these periods. In that case, you cannot increase the chlorine content by adding the normal dose of chlorine. The chlorine content will recover quickest by carrying out chlorine shock treatment.

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.
Does Liquid Chlorine Raise Ph
A: No. It does not raise pH. When dissolved in water, liquid chlorine enables Hypochlorous acid and Sodium hydroxide , which helps the level rise. However, when the Hypochlorous is deflated by UV, it births hydrochloric acid . The rate of this HCl is almost the same as the amount of NaOH therefore, any net effect on pH is nearly nothing or completely zero.

When Pool Water Temperature Rises
Bacteria and other organisms such as algae thrive in warm water. In addition, the amount of free chlorine decreases with rising temperatures.
Most pools are kept at a comfortable level of 86-88 °F. The temperature should be lowered to a range of 78-84 °F if there are a lot of swimmers or if the pool is used for athletic activities. You can use a pool thermometer to measure water temperature.
If the temperature rises above the recommended levels, you should shock your pool.

How Much Chlorine Should Be Used In A 15000 Gallon Pool
You need to achieve and maintain chlorine readings, from a test kit, of between 1.5 and 3.0 pH readings of between 7.4 & 7.8 total alkalinity readings of between 80 & 120 for best water quality chemically. Filtration is another factor in water quality. Add chlorine – liquid or granular – until you achieve those readings. It may take a few times of adding chemicals in order to know what your pool requires. There is no set amount for each and every pool. All pools react differently according to demand or use of the pool. Purchase a “Swimming Pools” book at your local big box hardware store for instructions for pool maintenance. And do it soon as pools are not forgiving if neglected. k

How Much Liquid Chlorine Must Be Added Daily
chem geek said:You can use rains to dilute the water even with the cover on — just feed the water from the top of the cover into the pool that then overflows to a drain . That’s what I do over the winter, mostly to keep salt levels in check. One has to be a little careful since the pool water can get dirty from what is pumped on the cover, but it’s not too bad .
chem geek said:Once you’ve killed off any nascent algae growth, then maintaining a minimum FC of around 11 ppm with the 150 ppm CYA would probably have a low chlorine usage losing only 15% or so per day so perhaps 1.6 ppm FC per day. The higher CYA level protects chlorine loss from sunlight even with the proportionately higher FC level. The main risk is if you ever have to SLAM the pool — it will take extraordinary levels of chlorine to do that. This is why we normally say that 80 ppm is a maximum CYA level.
How Often Should I Shock My Pool
How often you should shock your pool depends on how often the pool is used and how much exposure your pool is getting to sunlight. For general maintenance and upkeep, everyday to weekly shocking is ideal depending on the reading of free chlorine that should always be 3 ppm.
If you have lots of people swimming on a daily basis, you should test free chlorine and shock as required every single day and at least weekly when the pool is not very busy.

How Much Liquid Chlorine To Add To A Pool
First conduct a water test to determine the chlorine level. Water test kits are readily available at numerous stores and online, and come with detailed instructions to decipher how to read the results.
An important thing to mention here is that the chlorine that is measured is actually free chlorine, there is no differential.
To determine the amount of liquid chlorine you need to add, first consider the total water capacity of your pool. Most chlorine comes in packing suitable to be used per 1000 gallons of water. If the water capacity of your pool falls outside of that, there are chlorine calculators online to assist you in determining the correct quantity of chlorine to add.
It is recommended to keep chlorine levels maintained between 1 ppm and 3 ppm. Above 3 ppm concentration of chlorine in pool water can cause irritation to the eyes and skin of swimmers.
When adding chlorine, keep the pool pump running for proper dispersion and refrain from swimming until the level is below 3 ppm.
IMPORTANT NOTE! Liquid chlorine is an extremely harsh chemical and must be handled with precaution. It has a higher pH value than the powder form so it is highly likely the pH will need to be re-balanced after adding it. It is also highly corrosive and can cause burns or damage to pool equipment if not used correctly. Always handle any pool chemical with caution and wear protective clothing, gloves, and eye protection.

Using Sodium Hypochlorite In Your Pool
Sodium hypochlorite liquid chlorine is the best option to use in a saltwater pool system, especially when you need to boost law chlorine levels in your water. Use it in the treatment of water in swimming pools, spas, and hot tubs. When introduced into a swimming pool or hot tub, it is immediately available to destroy algae, bacteria, viruses, and other microorganisms due to its fast action.
To use Sodium Hypochlorite liquid chlorine effectively, measure the right amount for your pool and pour it evenly around.
Note that not all liquid chlorines come with sodium hypochlorite as the main ingredient, as some are made of calcium hypochlorite. You should take keen interest to know ingredients any liquid chlorine is made of.
For instance, Chlorox and In The Swim liquid chlorine are made of high percentage calcium hypochlorite, and you should not use them for regular chlorination, as this will raise calcium hardness, but can only be used when fighting green, black, and yellow algae in your pool.

Adjust sliders to calculate the amount of bleach or chlorine to raise free chlorine levels in the pool.
Chlorine is the most popular disinfectant for swimming pools. There are three main measurements for chlorine, Free Chlorine , Combined Chlorine , and Total Chlorine . Free Chlorine is most commonly tested because it represents the amount of chlorine free in the water for disinfecting. Chlorine is very effective at eliminating most microorganisms in the water that cause disease, bacteria, and algae. Some parasites such as Cryptosporidium and Giardia are resistant to chlorine and need to be treated with UV or Ozone.

More About Pool Chlorine
Swimming pool chlorine levels should be tested daily or every other day if a chlorine generator is used. Chlorine is constantly being consumed by sunlight and contaminates. It is important not to let the Free Chlorine levels reach zero. Once Free Chlorine is zero, there is nothing to protect the pool water from microorganisms and other contaminants.

Breakpoint chlorination is a level of chlorine at which point molecular bonds are broken apart. Conveniently, this is also the point at which chloramines, algae and pathogens are removed from the water.
For most situations, a level of 30 ppm of chlorine will reach the threshold of breakpoint chlorination and order will be restored.
Example: 20,000 gallon pool 7.8 lbs of Cal Hypo to reach 30 ppm
Heres a pool shock treatment chart to determine the amount of pool shock necessary to raise the chlorine level above the breakpoint threshold, which is usually around 30 ppm.
Not using enough chlorine to not quite reach breakpoint may not have the desired full effect.
Check for proper water balance, especially pH, in the range of 7.2-7.6, before adding the shock to the pool. High pH of 7.8-8.2 can render up to half of your pool shock completely inactive.
Proper filtration and circulation deserve some mention as well pool shock doesnt do it all alone. The pool water needs to be filtered to remove the microscopic remnants of organic matter that is destroyed.
