Liquid chlorine and granular shock have the same active chemical that sanitizes your pool, what changes is the strength and the way you use it. Liquid chlorine is less costly, unstabilized and comes in liquid form. Granular shock is stabilized and comes in a solid form that dissolves in your pool.
Powdered chlorine is the most typical form of chlorine used in a domestic pool environment. It is typically only slightly more expensive than liquid chlorine but it is much easier to use and has a lower pH, therefore has less impact on your pool's balance when used.
Liquid chlorine may be a good choice if you have a large pool, but the costs associated with it, and the available chlorine per pound could mean that chlorine granules are the better option. In the end, both liquid chlorine and chlorine granules will do their job and keep your pool clean and clear.
Liquid chlorine leaves no residue and can be up to 80% less expensive. Also, it's the most commonly used pool sanitation method. It's available in refillable containers, and it doesn't need dissolving as it's a liquid. On the other hand, powder shock is easier to carry and lasts longer.
Powder or granular chlorine is 65 percent to mid-90 percent. Liquid chlorine is basic or alkaline (high pH) and requires a conscientious effort for safe handling and storage. Although powder or granular packages offer greater convenience, they still require attention for transportation, storage and usage.

Liquid chlorine
They are identical in every way, with the exception of strength. Household bleach is usually a 6% concentration (although some of the cheaper stuff is 3%), while pool chlorine can typically be found in strength between 10% and 12%.
Are chlorine and shock the same thing? 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.
It is always best to shock the pool in the evening, when the sun if off the water. If not, the sun will suck it out as fast as you add it. You should use chlorine tabs in conjunction with shock. The slow dissolve tabs hold a chlorine residual in the water.
Pool chlorine shock is a high concentration of chlorine in a single dose. The idea behind shocking your pool is to quickly elevate the level of free chlorine in the pool, effectively killing all germs and contaminants.
Sodium hypochlorite (also known as liquid chlorine) is another frequently used option for shocking pool water. This is a common choice in pool shock because you can pour the solution directly into the pool without having to dissolve the chlorine in water beforehand.
All pool chemicals, aside from unstabilised liquid chlorine, are good for up to three to five years as long as they're stored in a cool and dark place away from sunlight and they're packed in air-tight containers.
It is recommended to wait at least 20 minutes to an hour after adding water balancing chemicals. You should wait 2-4 hours (or one full cycle through the filter) to swim from the moment you use calcium chloride in your pool. It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours.
Chlorinating Liquid is a popular choice among pool owners and can be used as a substitute when chlorinating tablets may be unavailable. Chlorinating liquid is not stabilized, which means it may require a chlorine stabilizer to help the chlorine last longer.
Using liquid chlorine raises the pH of the water.
When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH.
Dichlor is perhaps the most “best of all worlds” chlorine sanitizer. It is typically found in concentrations of 60-65%, which is comparable to cal-hypo. It is a powder sanitizer, which makes it easier to spread or broadcast around the pool than chlorine tablets.
Chlorine has a low pH level, and in order to maintain your pool water's clarity and balance, shocking weekly will allow you to quickly raise the chlorine level, which will rid the pool of contaminants, without lowering the water's pH levels.
Answer: It is true that pool chlorine is stronger than bleach. For bleach and water to be the same strength as pool chlorine and water, you would have to adjust the ratio, increasing the bleach and reducing the water. But no matter which chlorine you use, make sure to test a small area before doing the job.
Short answer: yes. Longer answer: it depends on the formulation. The label on every bleach bottle should tell you the ratio of sodium hypochlorite (and available chlorine) in the bottle to everything else. A higher percentage is generally better, as you'll need to use less bleach to treat your pool.
In theory, if you have a cloudy swimming pool, you can add chlorine to “shock it” and clear things up. Chlorine will get the job done. But, the amounts may vary and you may have to really pound the pool with chlorine to get the water totally clear.
How Often Should I Shock My Pool? Shocking your pool regularly will help to keep the water clean and free of contaminants. You should aim to shock your pool about once a week, with the additional shock after heavy use. Some tell-tale signs that your pool needs to be shocked are cloudy, foamy, green, or odourous water.
BUT, if you have to shock your pool during the day in broad daylight, you can still swim after adding shock. It's recommended that you wait one hour after adding shock with the filter running, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool.
While chlorine is an effective option for disinfecting swimming pool water, it's not without its challenges. In fact, chlorine can be harmful to your eyes, hair, nails, lungs, and yes, even your skin.
Having too much chlorine in your pool water can be dangerous. Exposure to high levels of chlorine can cause lung irritation, skin and eye damage, and provoke asthma. Not only is it bad for your health, but it can be bad for your pool due to the increase in chlorine.
