How Much Liquid Chlorine To Add To Pool & To Control Chlorine Level

How to add chlorine to your swimming pool

It is to optimize its oxidizing and disinfecting power, chlorine must be perfectly dosed. A too high may irritate the skin and eyes of bathers, while too low will not allow water to be sufficiently cleaned and then require the use of a clarifier or flocculant. This is your main answer to the question of how much liquid chlorine to add to pool?. But there is more.

Raising Chlorine With Dichlor Granules

Use dichlor chlorine for indoor pools and spas.

Dichlor, or Sodium Dichloroisocyanurate, is also popular, but is used more for above-ground pools and spas.

Some advantages of dichlor:

  • Fast dissolving. Great for times when a quick dose of chlorine is needed prior to using the pool.
  • Only a slight affect on pH, which is about 6.7, and is also good for spas where pH is notoriously hard to control.
  • Does not have any effect on total alkalinity.

A few disadvantages of using dichlor:

  • More expensive than trichlor.
  • Not recommended for chlorinators, feeders, or floaters as it dissolves too fast.

First Step: Prepare Pool Water For Shocking And Testing

Why is my pool still green after adding chlorine, and is it safe to swim in a pool with algae? Not necessarily. Issues such as bacterial infections and skin issues can occur if you swim in water with algae.

Algae will remain in your pool after shock if youve had insufficient chlorine and an overabundance of metal elements in the pool water. Therefore, to start the cleaning process. Remove all the debris from the pool with a leaf net and then let the smaller dirt fragments settle.

Is your pool still green after shock? A common DIY issue. Normally a pool cleaning service or the next step of DIY will tackle these next three things to take your pool back to its crystal clear shape: the filtration system, the correct chemicals, and patience. We recommend a professional to clean the pool or teach the techniques, especially when dealing with pool chemicals. Here are some guidelines for taking your pool from green to refreshing clear.

When Should You Add Chlorine To A Pool

How to add chemicals to your pool in 5 Easy steps

Preferably open the pack in the open air, but out of the wind. For chlorine shock treatment, 3 measuring cups of 40 grams of chlorine granules should be added per 10 m³ of water. Ideally, this should be added after swimming or in the evening to ensure that the product can spread well throughout the pool.

What Is Liquid Chlorine And What Is It Used For

Liquid chlorine is a form of chlorine where a very high level of chlorine gas is mixed with caustic soda to create a liquid product. The liquid chlorine is very highly concentrated because of the difference in the production of this product. Although some pool owners will use liquid chlorine at their homes, this pool sanitizer is used in commercial pools most of the time.

In a commercial pool, the liquid chlorination would come in large drums, and it would be administered to help keep chlorine levels stable in a large and high-use pool. Since it is a bit stronger, it can be smarter for a pool with higher bacteria levels.

What Is A Poolstabilizer And How Does It Work

Cyanuric acid , also known as pool conditioner orstabilizer, can be bought in liquid or powder. Without it, UV rays causechlorine to vaporize, thus making your pool susceptible to bacteria causingnumerous infections. In the simplest of terms, stabilizer enables your chlorineto kill microscopic organisms and remain in the water longer, by acting as asunscreen.

We will figure out how to add stabilizer to pool without skimmer in the following section:

How Much Liquid Chlorine To Add To Pool

How much liquid chlorine to add to Pool? With or without a stabilizer, the optimal chlorine level in a swimming pool is between 2 and 3 mg per liter of water.

In other words, 2 or 3 ppm . To correctly dose the chlorine in your pool, it is important to know the precise volume of your pool and to be patient to avoid overdosing. Proper water analysis is the key to a good chlorine dosage. So the question comes, how much liquid chlorine to add to pool?

Before starting with the question, how much liquid chlorine to add to pool?, you must know the characteristics of your water. Three parameters must be taken into account:

How To Add Chlorine Tablets To Your Swimming Pool


Finally, the most important part of this post how to add chlorine tablets to your swimming pool.

What do you mean how to add, why cant you just throw them in the water? Thats what theyre made for.

Great point. Yes, chlorine tablets are designed to go in your water. However, theyre not mean to be left dissolving on the floor of your pool.


Leaving chlorine tablets on the bottom of your pool can cause permanent staining and bleach liners. Its also the least effective way to use them.

Tablets sitting at the bottom of your pool are nowhere near your pools skimmer line. So they dissolve slower and release sanitizer unevenly. When you use chlorine tablets this way, most of the chlorine gets wasted, and you end up having to use even more.

So instead of doing that, here are 4 much better ways to add chlorine tablets to your swimming pool.

Youve probably seen this classic pool accessory a few times. You may already be using one now.

Theyre the small plastic containers that float on the surface of your water. Sometimes they have funny looking duck or animal on top, other times theyre blue and look like the one in the picture above.

The beauty of floating dispensers lies in their simplicity. They hold just a few tablets and keep them safely contained to gradually dissolve. As the dispenser floats across the surface of your pool, it releases chlorine into your water.

Why Is Raising Swimming Pool Chlorine Important

This Page at a Glance

If your pool at least partially relies on chlorine as a sanitizer and you find your chlorine level to be low, then it is critical you adjust the chlorine level up.

You generally want to maintain a level of 1 3 ppm of chlorine in your pool, although for commercial pools they generally need a level of 3 5 ppm. The low limit of 1 ppm is important, as levels less than 1 ppm are not effective at keeping the water sanitized. Because of this, experts often recommend you keep your residential chlorine level at 2-3 ppm. The diagram below shows where your home swimming pool chlorine level fits in a chlorine range of 0 10 ppm:

A visual guide to your swimming pool chlorine level.

It Should Not Be Done Together

While shocking and adding algaecide is effective in getting rid of algae, 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.

The Floating Chlorine Dispenser

If you grew up around pools, you most certainly remember swimming around this floaterand accidentally kicking it during your underwater flips. Unfortunately, nostalgia is where our warm feelings for floating chlorine dispensers should end. This low-maintenance and fairly inexpensive deviceyou can get one for as little as ten dollarsproves that sometimes you get what you pay for. Womp womp.

Whats the problem with floating chlorine dispensers? Well, theyre just not consistent. If they get caught in one placewhich they often dothey can release too much chlorine in one area of your pool . They release chlorine into more or less slow-moving waternot the water that flows directly through your pool filter as part of the circulation of your larger system. This means that the chlorine dispensed is not spread evenly throughout your swimming pool. And if its not dispensed evenly, its not effective. Skip this nostalgic device and read on.

How Much Chlorine Should You Add To Your Swimming Pool

Does Adding Chlorine To A Pool Make the pH rise?

Ideally, the chlorine concentration of your swimming pool should be at least 1 part per million , and not go above 3 ppm.

Staying within that range is the safe and smart way to balance protection against contaminants with the risks of having too much chlorine in the water, which can cause eye, nose, lung, and throat irritation.

To ensure your pool water has the right amount of sanitizer, regular pool water testing is essential. You can use test strips or test kits to determine the exact levels of chlorine and other chemicals, and then fine-tune them as necessary.

Adding Chlorine Granules Directly Into The Skimmer

  • Turn on the pump. Give it a few minutes to circulate and blow out the air that might be in the lines.

  • Put on goggles and gloves. Even though you are not mixing the granules with water, the fine grains can irritate skin and eyes.

  • Take off the skimmer cover. Open the container of chlorine and scoop out the granules. Manufacturers supply either a scoop or measuring cup.

  • Pour the chlorine into the skimmer, reaching down into the skimmer as you pour. Do this slowly so it doesn’t spill onto the pool tile.

  • Replace the skimmer cover. Let the pool run for one to two hours before swimming.

  • Things You Will Need

    Liquid Chlorine Vs Granular Shock

    Liquid chlorine and granular shock are both unstabilized. As we know from above, the unstabilized chlorine means that cyanuric acid levels in the chlorine or shock are not high. Essentially the products do not have any stabilizer in them.

    Both liquid chlorine and granular shock are known in the pool industry for having higher levels of available chlorine. Essentially you will need to chlorinate your pool daily, and then you will need to shock it from time to time. When you shock the pool, you must use a sanitizing product that raises the chlorine level quite high and then lowers it back down.

    Granular shock and liquid chlorine are known to kill all living microorganisms and bacteria in the pool. Essentially there is nothing that is going to escape what these chemicals can do. Therefore clearing cloudy pool water is much easier with liquid chlorine and granular shock. If you have an algae problem, this is one great way to fix it.

    However, liquid chlorine and granular shock are not the same product. The liquid chlorine tends to be quite a bit less expensive than granules. In addition, it is heavy to carry around and has a shorter shelf life. Although liquid chlorine tends to be one of the most popular options, some will like how easy the granules are to work with.

    Probably the most intimidating part of swimming pool maintenance is understanding chlorine. What follows is an overview written in plain english so you understand the difference between the three main types of chlorine used.

    Granular Chlorine

    The granular chlorine is used once a week to shock the pool or once a day as a daily dose of sanitizer. A pool shock involves raising the level of chlorine in the water so high that it kills bacteria and neutralizes organic material. The amount you will need depends on the amount of water contained in your pool. You can read the instructions on your chemical container or talk to your dealer for more details.

    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.

    Third Step: Shock The Pool

    Why is my pool still green, you are wondering? Well, its a chemical imbalance. So first, ensure the pool has a pH of 7, then shock the pool with chemicals. Take your liquid chlorine and disburse it around the pool evenly, and then turn on the filter.

    Let the entire liquid chlorine circulate in the pool for several hours before you brush the pool. Be thorough when brushing. You can also use a suitable quality algaecide to clean the pool. Always consult with a professional before handling and adding any amount of chemicals.

    Way #: Automatic Chlorinator

    An automatic chlorinator is a unit thats installed in the filter system, and its the best way to keep your pool water sanitized using chlorine tablets.

    The chlorinator gets filled up with tablets and chlorine is then slowly released, feeding the pool a steady stream at all times via the return jets.

    As mentioned earlier, there are both stabilized and unstabilized tablets you can choose from. Youll have to make sure the chlorinator you buy is compatible with the tablets youre using.

    Most trichlor tablets are 3 wide, and the chlorinators are built to this spec. However, some calcium hypochlorite tablets are only 1 wide, and will need the proper sized chlorinator, as theyll dissolve too quickly in a 3 model.

    Still, this is the best way to add chlorine to the pool, although admittedly, its a bit expensive, as units can cost anywhere from $50 to $300.
