One of the most commonly used chemicals across the globe is chlorine. Chlorine for pools is used for bleaching, disinfection of drinking water, and in swimming pools to help keep the water clean and healthy by destroying bacteria, germs, and algae, in addition to playing an important role in the manufacture of plastics and polymers.

Buying Guide for Best Chlorine For Pool in 2023

Chlorine for the pool is a chemical sanitizer that is usually purchased in the form of a tablet, powder, or liquid, which is then prepared and applied to your swimming pool to keep the water clean and safe to swim in.

Chlorine is effective against a wide range of microorganisms that cause diseases like cholera, hepatitis A, and dysentery; Other people’s feces, pee, sweat, spit, and dirt in the pool; Dirt and waste from the outside world; Algae growth and spread are unavoidable.

It is best to chlorinate your pool in order to keep the water safe and your family healthy. It is one of the most effective methods for eliminating all bacteria, viruses, and protozoa from stagnant water. The most effective way to apply this chemical to the water in your swimming pool is by pool chlorine tablets.

Chlorine tablets essentially prevent the growth of algae, keep the pool walls and floor clear of stains, and eliminate any odor that may otherwise develop in your pool. This guide will assist you in choosing the right chlorine for pool that you can use for your pool. We’ve covered all of the important considerations in the guide to help you make the best possible purchasing decision.

Features of the Best Chlorine For Pool in 2023

Types of Chlorine For Pool:

Pool chlorine comes in two varieties

  • Tablet Chlorine:

To avoid peaks and valleys in your chlorine levels, use a slow-dissolving tablet for daily chlorination. Chlorine tablets are often stabilized, – this means they are shielded from the sun’s UV rays. Because of its nearly neutral pH, tablets or sticks gradually release chlorine without dust or binders, which helps to regulate your pH levels.

  • Pool Shock:

The second form of chlorine to discuss is shock chlorine for pool shock treatment and/or algae removal. These chlorine forms sanitize the water by killing bacteria, breaking down toxins, and preventing algae development. They also break down chloramine bonds, resulting in a very strong chlorine odor in the water.

Determine what is best for you while choosing a chlorine product to use. Bear in mind the location of the pool as well as the need to maintain a chlorine level of 1-3 ppm. Maintaining this amount will ensure that your pool remains clean and safe to swim in.

There are several reasons why chlorine tablets are preferable to other types of chlorine, such as liquid or powder.  It is considered to be the best chlorine tablet for swimming pools because of its superior cleaning abilities, which keep your pool free of dirt and germs. Chlorine tablets are significantly less expensive and come in big packets. It’s also really easy to use. You can easily calculate how much your pool would take.

Calculate Chlorine Demand

The first thing we’ll do is figure out how to calculate the chlorine demand. The amount of chlorine needed to keep your swimming pool clean is known as chlorine demand. Bacteria and algae will not be eradicated if you use too little chlorine.

Adding a lot of liquid chlorine for pools to your pool will boost your costs and leave your pool water murky. Extremely high chlorine levels in the pool water can also damage the delicate pool circulation equipment. It’s important to know how much chlorine you can apply to your pool. The pool’s shape and size are important, but the amount of water in the pool is the most important factor.

The chlorine demand formula can be calculated in a variety of ways. The best thing you can do is invest in a high-quality automated meter that will give you an exact reading so you can make sure you have the correct amount of chlorine.

Stabilized vs. Unstabilized Chlorine

On the market, there are two types of chlorine: stabilized and unstabilized. The stabilized chlorine lasts for longer and dissolves more slowly than regular chlorine. Even when exposed to UV rays from sunlight, some will last a long time. Since stabilized chlorine can work better in the sun, they are better suited for outdoor pools. They’re equally effective for both above-ground and in-ground pools.

When chlorinating small pools or hot tubs, unstabilized chlorine are ideal. They’re also perfect for indoor pools that aren’t exposed to the elements. This chlorine dissolves a lot faster because they are unstabilized, and they will lose their effectiveness if they are exposed to UV rays in sunlight.

Tablet Size

Chlorine tablets are usually only available in two types. 1-inch and 3-inch variations are available. The amount of tablets you’ll need to treat your water is determined by the size of your pool and the type of dispenser you’re using. The floating chlorine feeder may only carry one chlorine tablet, whereas larger models may hold multiple tablets.

It’s simple to figure out how many tablets you’ll need for your pool. There will be a guide on the label that explains how many of their tablets are needed per 10,000 gallons of water. It’s usually just one or two, but it’s still a good idea to double-check. To make sure your pool gets the right amount of chlorine, follow the directions.


Chlorine is made up of a variety of chemicals, but the most important thing is that they contain at least 90% chlorine. It is suggested to purchase stabilized chlorine, which won’t dissolve as quickly in the light. Trichloro-s-triazinetrione is the primary ingredient in most chlorine for pools on the market.

Most manufacturers, of course, add a variety of other chemicals to the trichloro-s-triazinetrione in order to extend the chlorine’s useful life. The chlorine for the swimming pools would be most effective at destroying algae, bacteria, yeast, fungi, viruses, and any other nasties lurking in the water at these concentrations.

The chemical mixture is intended to extend life by slowing the rate at which they dissolve. Some of these reduce the rate of chlorine release to such an extent that their overall efficacy falls well short of what you want. This means you will need to use more amount of chlorine to achieve the desired chlorine levels.

It’s not easy to find out just what balance you need to hold. Consider it this way to make it easier to comprehend: If your pool is mostly clear, you can use chlorine with a high trichloro-s-triazinetrione concentration. If your pool is vulnerable to algae growth and other problems, chlorine with a higher concentration of algae-fighting additive chemicals should be used.

Dissolve Speed

One of the most significant considerations is the rate at which a chlorine tablet dissolves. If you do it too soon, you risk “shocking” your pool with a huge amount of chlorine in a short amount of time. If the chlorine dissipates, the water is unpleasant to swim in.

If you go too slowly, you risk not getting enough chlorine in your pool to hold the chemicals in check, causing your pool to turn an unsightly shade of green. You’ll need the perfect dissolve speed, which takes about 7 to 10 days for chlorine to dissolve.


It’s crucial to think about the packaging. Most businesses, particularly those with large containers, will individually wrap their chlorine tablets. This prevents them from splitting up, but it can be a little messy because each one must be unwrapped before being used.

Since chlorine is such a powerful chemical, you’ll need gloves, possibly goggles, and a mask to complete this fiddly job safely. Since pool chlorine tablets are fragile and can break if dropped or mistreated, the package size will also play a part.

When tablets are split, they dissolve more quickly, which isn’t ideal because you’ll need more tablets to maintain the same chemical equilibrium in your tub. Smaller box sizes are preferred since larger ones are more likely to be lost and damaged during delivery.

Available Prices

The majority of chlorine tablets on the market are fairly priced. Of course, the total cost of pool maintenance can be very high. The explanation for this is that there are so many factors that come together to ensure that your pool is well-kept and clean. If you can save even a few bucks, it’s a good idea.

As a result, the net cost of maintaining your pool will be reduced. The cost varies between Rs 160 and Rs 500 per kilogram. It is suggested that you purchase chlorine for the pool according to your preferences.

FAQs of the Best Chlorine For Pool in 2023

What is the most important component of chlorine tablets?

Calcium hypochlorite is the main ingredient in these products, which is commonly used to clean water in swimming pools. Since the tabs contain cyanuric acid, make sure to verify the levels before purchasing them.

What characteristics distinguish a healthy chlorine tablet?

There are a few interconnected features to think about when choosing the chlorine tablets for swimming pool. They have to do with absorption rates (how quickly it dissolves), bacteria-killing and algae prevention, and tab breakability.

What Is the Right Amount of Chlorine for Using?

The amount of chlorine for the pool required is determined by the size of the pool, the amount of debris in the pool, and the type of pool. The amount of chlorine tablets you need is usually determined by the number of gallons your pool will accommodate. The general rule is that a single tablet can chlorinate 5,000 gallons of water.

When adding the chlorine tablets, you can still round off the number of gallons you’re adding to the next 5,000. For example, if your pool holds 16,000 gallons, add four tablets (or the equivalent amount for 20,000 gallons) to it. Add three tablets if the tank capacity is 15,000 gallons. You would not have less chlorine per gallon in the pool if you do it this way.

When can Chlorine Tablets be used?

The chlorine for swimming pool is a common choice among swimmers and pool owners who understand their value. It is recommended for those concerned about the safety and purity of their pool.

These tablets function well with Jacuzzis as well as swimming pools, so if you own a hotel and want to present clean and transparent Jacuzzis to your guests, these tablets are for you.

When is the right time to chlorinate your pool?

Chlorinating the pool is better done in the evening or at night. The primary explanation for this is that chlorine would have enough time to do its job and remove bacteria and algae from the pool. If liquid chlorine for pools is added during the day, the sun can interfere with it, causing the tablet to dissolve more quickly.

This means it would not have the time it needs to do a good job. If you have an enclosed pool that is not exposed to UV rays, you can add chlorine tablets at any time of day.

What is the best chlorine for pools?

Video Transcript:

Initially, I’m going to go over the different kind of sanitizers you can use for your pool otherwise known as chlorine types I’ll be going over the benefits and drawbacks of each type of chlorine and I’ll let you know which one is the best to use for your pool let me start off with what I think is the best chlorine type for your pool which is liquid chlorine or the equivalent of this would be your household bleach it has the same active ingredient just in a smaller percentage what I like about the liquid chlorine is per volume it has 12.5% of chlorine which is about equivalent to one pound bag of shock.

Since it’s measured in a liquid form and on a dry form it’s hard to correlate it but if you just break it down you’ll see the liquid chlorine has much active chlorine you would find in again a one-pound bag of shock at your local pool store another thing that I like about looking fluorine is that it’s fast-acting and it’s safe for all pool types and it’s very easy to use the liquid forms keep it stored into the pool and liquid chlorine doesn’t really affect the ph so as I move the ph up or down in your pool and liquid chlorine doesn’t contain any other elements like conditioner or cye and one of the drawbacks of liquid chlorine is has a very short shelf life if you purchase it from the store.

It doesn’t rotate its stock or if you keep it in your backyard for a long period of time it will get weaker over time and the next type of chlorine is a bag of shock like this right here this is a trial or shawl they also have Dyncorp shock and I’ll show you the cow hypo in a moment shock is a convenient way to sanitize your pool has a really long shelf life also about one or two years just a convenient way to carry chlorine back to your pool the only problem with the trial or shock it also does have conditioner in it so it’ll raise your conditioner level in your pool it also has a very strong smell to it.

When you add it to the pool and if you use large amounts of the Trico shock it will lower the ph in your pool next up is Kal hypo or calcium hypochlorite there are a couple of drawbacks of using Calla hypo in a pool it’ll cloud the water when you pour it indirectly also it’ll raise the calcium level in your pool it does have a higher ph or to raise your ph if we use large amounts of it towel hypo doesn’t include any conditioner or cyanuric acid it was a great alternative using a shock cyanuric acid in it and they also make Kal hypo tablets which is really convenient they don’t have any sign Erik acid in them.

So they won’t raise the level of your conditioner in your pool one caution however if you’re gonna switch over from trial or tablets to Kal hypo you don’t want to use the same feeder that you’re using for the trial or tablets you want to get a whole new feeder for the cow hypo tablets otherwise it could cause a chemical reaction or explosion the next type of chlorine is dike or this is a granular form of chlorine cycler is a convenient way to add chlorine to your pool one of the nice things.

About Dyke lore is that it’s ph neutral so won’t raise or lower the ph in your pool the Dyke lure is a granular type of chlorine they also sell decor in a powdered form or shock form I wouldn’t recommend that one that one has a lot of other ingredients that could really cloud up your water but the granular dichloro is fine and the safe for all pool surface types and one of the drawbacks to dichloro is about half of the weight of dichloro is conditioner our sign Erik acid so if you add a five-pound bucket of decor to your pool you’re adding about 2 pounds of sayonara acid also the next type of chlorine is trying color.

You have the tablet form like this here note that I’m using tablets in your pool that half of the weight of the tablet is cyanuric acid or conditioner so this will also raise your conditioner level in your pool if you is a 50-pound bucket during the season about 20 pounds of that sign Erik acid you’re adding 20 pounds of sign Erica acid to your pool and track Laura is a strong as chlorine on the market most tablets are 90 to 99 percent trial or one of the drawbacks to trial or disasters that have so much cyanuric acid it also can stain your pool surface so be very careful when using the trial or in a pool skip a fiberglass or vinyl pool I don’t recommend using the trial or is it in fact most fiberglass pools warranties will be voided if you use try flooring it if the strike laura has so much cyanuric acid.

In it also lowers the ph in your pool you put large amounts of trial or in your pool they also sell a granular form a trial or to fight algae this is the hosta algae ban it’s the one that I used in my pool route this is 99% active trial or the granular try clothes great for pools of black algae or stubborn mustard algae one caution is that it could stain the surface of your pool so only use the trial or and a white plaster pool can use it in a color plan your pool at the color plasterer is really old.

And has a lot of modeling I would not use trial or in a fiberglass vinyl or pebble tech pool but the granular trial or is highly effective against algae one caution about high sign Erik acid levels or conditioner levels in the pool you want to keep your sign Erik acid level between thirty and fifty parts-per-million you have a saltwater pool and go as high as 80 parts per million we let the sign air castle level get too high in your pool but make the coin a lot less effective you’re gonna find algae blooms with high chlorine levels you’re gonna have to keep your chlorine level much higher than normal to keep chlorine in your pool besides the sanitizers.

That I show you here in this video another great way to add chlorine to your pool is with a saltwater generator a saltwater system and a saltwater system will convert the salt into a gas form of chlorine so it’s a great effective way to add chlorine to your pool that’s a look at the different type of sanitizers or chlorines that you can use for your pool in your pools comm is a proud sponsor of swimming pool tips and have been helping owners find the right pool parts of 2001 with over 50,000 pool parts in stock order online today and have your parts delivered right to your door.

What precautions should I take while utilizing chlorine for a pool?

Since chlorine for the pool contains a number of chemicals, it must be handled and treated with care.

Keep the tablets cool, dry, and well-ventilated. Remember that exposing chlorine to bleach or even liquid chlorine for pools will result in the release of harmful gases, including the possibility of an explosion.

Action with moisture or dirt of the pool water can also reduce the effectiveness of chlorine tablets. Chlorine for the pool is safe to use as long as it is properly packaged and stored. Here are some additional safety precautions to consider like:

  • Keep pets and children out of control.
  • Do not eat chlorine tablets because they can be toxic.
  • If you see chlorine fumes coming from your tablets, take them outside to avoid breathing them in.
  • To handle some kind of chlorine, wear gloves.
  • Do not combine with other chemicals.
  • Mixing with other forms of chlorine is not a good idea.

How much chlorine do I add to my pool?

Video Transcript:

How much chlorine do I need to add to my swimming pool this is such a straightforward question but it’s in actuality it’s totally a loaded question there are so many ways to answer that and it’s really hard to quantify something definitive for you like put in one gallon of this or one cup of that the first thing that I need you to appreciate is that when you’re talking about how much chlorine your pool needs to have are we starting from the point where there’s zero you tested and there’s zero chlorine and to you that sounds really straightforward but in actuality, there’s some sort of negative number happening here there’s bacteria and organic debris in the water and you could put in a small amount of chlorine.

Enough that it should build one part per million of free chlorine in a 10,000 gallon body of water and yet it doesn’t so what happened there well it’s because there’s a buildup of things that the chlorine needs to kill and so you actually need to add more than the number that you need and you’re compensating for this unknown number of bacteria currently in the pool bacteria and organic debris so when you’re saying well how much just tell me how much I need to add I don’t know nobody knows how much bacteria is in your pool all we know is that there’s zero chlorine a very straightforward question would be I’m at one part per million free chlorine I have a 10,000 gallon.

Body of water I want to go up one part per million of free chlorine that’s really easy because we’ve already established the baseline of one it’s not an unknown quantity at this point when you have zero chlorine in your water we there’s an unknown quantity we don’t know how much there is and that’s the hard part to definitively articulate to new pool owners is I don’t know how much to add you don’t know how much dad you have to keep adding it until such time as you overcome this bacteria and organic debris load in the water and you start to be able to register and hold a free chlorine level and that’s something that I’ve explained before and I often get a lot of comments.

From people that say yeah okay I get it, there’s, we don’t know how much but like seriously just how much stuff do I need to add I don’t know are you talking like a cup of something or gallons of something else and so that’s what I wanted to kind of clarify with this video and I’m gonna go over a lot of numbers here and you don’t need to remember these at all these are something that I’m going to reference and then I’m gonna hold them up at the end of this video so you can see for yourself and you can back up and go over the numbers again and I’m going to be comparing.

All of these values to a 10,000-gallon body of water or 40,000 liters but 10,000 gallons and the idea there is that you can then take these numbers and apply them to your pool whether it be smaller than 10,000 or you have 20,000 or 30,000 or 40,000 gallons so you can still use these numbers to determine how much physically how much chlorine product do I need to add to this water and so I guess we’ll start with liquid chlorine that’s the one that I like to recommend a lot of people to use it doesn’t have cyanuric acid in it so when you add the liquid chlorine to the water.

R you’re not continually building up your cya levels to the extent that one day you’re gonna have to partially drain and refill with fresh water so that’s one of the reasons reasons I like liquid chlorine is it’s not stabilized so it’s something that you can add to the water readily without building up this residual value of something that you’re gonna have to deal with later with you know a drain and refill in some areas draining and refilling pools is getting really expensive in some areas it’s just not allowed at all so you definitely need to be aware of the chlorine you’re using and that’s one of the reasons why I like to look to liquid chlorine so it’s readily available it’s cheap pretty much everybody has access to it how much do you need to add well let’s say that you needed to go up one part per million of free chlorine in a 10,000 gallon body of water you would need 10 point 7 fluid ounces of liquid chlorine and to convert that to metric for some people 330 milliliters is how much you need and that would be to go up one part per million now let’s say you needed to go up five parts per million in that same 10,000 gallon body of water that would be 1 point 7 quarts or 1.3 6 liters to go up 5 parts per million of free.

Chlorine now some other useful conversions here because these numbers still might not be useful for you eight fluid ounces is equal to one cup four quarts is equal to one gallon so that might help you to figure it out so let’s just work with these numbers for a second you’ve got I’ve got 10,000 gallons to go up one part per million well let’s say you’ve got a 30,000 gallon pool you want to go up one part per million so then you would take these numbers and even times them by three so you know approximately 33 fluid ounces something like that approximately 990 milliliters or one liter approximately to go up one part per million in a 30,000 gallon.

A pool that’s how these numbers work and how you start to work with them to determine physically how much chlorine product do I need to add and just to conclude on the liquid chlorine there that’s assuming a 12% concentration of liquid chlorine so let’s talk about another chlorine option because not everybody uses that maybe that’s not what you’ve got maybe you’ve got something called Kal hypo and I’m gonna use a sixty-seven percent strength Cal hype was the example although it does range from 47 to 78 for this example at 67% so again we’re gonna work with a 10,000 gallon.

Body of water we need to go up one part per million in chlorine that’s two ounces of Cal hypo and that 63 grams in metric so the at 67% if we needed to go up to five parts per million instead of one part per million again this is 10,000 gallons of water we’re going up five parts per million with a 67% Cal – product that’s going to be ten ounces of Cal hypo or approximately 315 grams now dichlorine trial or chlorine I’m just gonna go over the Daikeler numbers which are essentially the same as the Cal hypo numbers I went over the Daikeler concentration that I’m talking about is 62%.

So to go up one part per million in 10,000 gallons of water is 2.1 ounces of dye Korsak’s t two percent and that’s 65 grams if wanted to go up to five parts per million in a 10,000 gallon body of water that’s going to be ten point seven five ounces or approximately 320 grams of the Dyke lore and I just want to say when I’m talking about Dyke lore and trial or these are stabilized forms of chlorine they have cyanuric acid in it every time that you add that product to your pool you’re increasing the cyanuric acid level by a lot, not a little and the range you need are 30 to 50 parts per million of cyanuric acid and that helps to prevent the chlorine in your pool from burning off every day in the Sun when those levels exceed 50 exceed 80 and definitely when they exceed 100 it becomes difficult for your chlorine to be effective in the water and so I strongly encourage all pool owners.

Who is asking this question you know how much chlorine do I need to add to my water you first need to consider choosing an unstabilized form of chlorine-like liquid chlorine would be a great example you can use dichloro or try color but be aware that they’re stabilized and you are adding cya to the water every time you use them so I would encourage you not to but I hope that I’ve been able to quantify in some way for people how much do I need to add to my pool to increase the chlorine level first we need to determine that you have some chlorine so that that is you keep adding it until such time as you can achieve at least something other than zero/

So now we know that we’ve overcome the organic debris load that was existing in the water and you can start to use these values that I’ve talked about to dial in on physically how much chlorine product you need to add and I’m going to show you these numbers now if you found this information helpful please be sure to like this video and subscribe to my youtube channel and you can check out my website swimming pool Steve calm.

How does chlorine in a pool work?

When chlorine is applied to water, it creates a new material called ‘hydrochloric acid,’ which combines with harmful bacteria, viruses, and other microscopic threats to render them harmless. Chloramine is another name for combined chlorine.

And don’t worry: the concentrations of hydrochloric acid discussed here are much less toxic to humans than allowing those microscopic nasties to live and breed freely in your tub.

Finally, since this reaction works best under the right pH conditions, you’ll want to keep an eye on your chlorine levels if you’re using it. Sunlight speeds up the process, so if your pool is constantly in the sun, you’ll burn through more chlorine.

How to add chlorine to the pool?

Video Transcript:

Oh, youtube just want to show you how to add chlorine this is my new full setup so this is the machine that controls and filters the water so it’s currently running right now and we gonna add more chlorine to this chlorinator so I have this automatic chlorine container the chlorine is inside here and we can use this dial here to adjust the level of I guess the saturation or amount that the chlorine gets put into the poll so let’s get started I’m going to stop the machine first and there you go to make sure that the pump is stopped because if I don’t do that when I opened this is actually gonna spurt out water.

And on my face and it’s not gonna be good because it’s gonna have chlorine in it and chlorine is actually a poison so it’s not going to be good anyway so we are going to fill it up as you can see it’s about halfway full and there are actually a little bit smaller I’m pretty sure on the inside than the new one so we’re just gonna make a new one and you’re gonna have to make sure that the water is not full when you drop the tablet because you don’t want it to be splashing on your face so there you go I usually just keep it filled up all the way like that well not all the way on the top but you know leave a little bit of space.

And then just get the cap back on and then screw it in and that’s it make sure this is just hand tight by the way and then I’m just gonna turn the pump back on making sure that it is running Schedule C right now it says priming I’m gonna wait until it’s completely primed and it’s still priming okay you see how it says run scheduled running schedule no no actually says running speed three I wanna yeah you see that it says running schedule just for a short period of time that’s what I want I want to make sure that it’s running schedule so that it goes with my regular schedule.

And otherwise when I just turn it on is going to keep it on all the time and I usually keep my chlorine at about four and a half or so and right now my chlorine is actually kind of low so you can put a tablet or two inside the skimmer and I’m gonna show you how to do that so you just gonna take a tablet-like this and let’s go through the skimmer and put it in okay so typically if you don’t have a chlorinator like I do you can actually just chlorinate the pool by dropping the tablet.

Or two inside the skimmer and this is going to do the same thing basically when you have a chlorinator obviously you don’t have to do this but my pool chlorine level is kind of low so I’m gonna shock the pool basically put a little bit more chlorine than normal to make sure that the chlorine level gets up to speed faster so I’m gonna put one tablet in a skimmer and I already loaded my chlorinator so this is gonna get my pool chlorinated really fast in probably the next a few hours.


You can keep your swimming pool water crystal clean without wasting a lot of money if you use the best pool chlorine tablets in the right amount and at the right time. Make sure you aren’t chlorinating the pool too much. Match the amount of chlorine you add to your pool’s recommended chlorine demand.

Last but not least, make sure you use chlorine for the swimming pools safely and only for the purposes intended. Take all of the safety measures, and keep it out of the hands of pets and children. Hope this guide of ours will provide you with all of the best chlorine for pool information you’ll need to keep your pool water in tip-top shape.
