How To Choose The Right Chlorine Tablets For Your Pool

Clear Water Maintenance for Small Pools up to 5,000 Gallons: Clorox Pool& Spa

Chlorine tablets come in one-inch and three-inch sizes. We recommend the three-inch tablets because theyre easier to handle and, depending on their popularity in your area, might even be less expensive than the one-inch version.

We also recommend the three-inch chlorine tablets because they provide sanitation for 5,000 gallons of water per tablet, meaning you can use fewer of them, which can also save you money.

To know how many tablets to use, youll need to know your pools volume. If you dont already know how much water your pool holds, use this pool calculator to quickly and easily figure it out.

To use the right number of tablets, always round your pool volume up to the nearest unit of 5,000 gallons. For instance, your pool has a capacity of 20,000 gallons, you would add four chlorine tablets. But if your pool holds just 16,000 gallons, youd still use four, three-inch chlorine tablets. Its that easy.

It implies that whether for a 20000-gallon pool, for 15000-gallon pool, or a 10000-gallon pool, you will be required to have chlorine of about 0.00013 ounces per gallon of pool water.

Adding chlorine calcium hypochlorite, sodium hypochloriteto your swimming pool in the evening, instead of the morning can reduce cut your chemical costs BY 50%.

How Much Chlorine For 1000 Gallon Pool

To know the amount of chlorine to add to your pool volume, you need to always round up the pool volume to the nearest 5000 gallons of water. But a thousand gallons of water since its not up to 5000, will consume 3 oz. of chlorine. Add this quantity to your pool while the filter is running. This quantity of water will raise your pools chlorine level to 3 ppm.

Dpd Powder Chlorine Test

There are a number of ways to test your water chlorine levels including test strips and dropper bottles, however the more accurate and the way I recommend testing it is with a DPD powder test kit.

When you use this testing method, you will be able to get your chlorine level accuracy within .5 or .2 ppm depending on the amount of water used during the test. It is much more difficult to get that accurate of a reading when trying to depend on the human eye to match colors in determining the levels.

Chlorine Application Frequently Asked Questions

How Much Chlorine To Add To Pool Per Gallon

How Should I Apply Chlorine To My Pool?

You can either feed the liquid chlorine through your pools mechanical chlorinator, or pour the solution directly into the pool preferably while the pools filter is running.

When Is The Best Time To Apply Chlorine?

The first thing you should take note of, in regard to chlorine application is sunlight. Before any application, make sure theres no sunlight, which leaves early mornings and evening as the best time to apply chlorine in your pool.

How Much Chlorine Should I Add To My Pool?

That depends on a few things. If you add chlorine to the pool while the filter is running , you may get a slightly different concentrate than if the filter isnt running. The most important factor though is the size of the pool. Youll need about 52-104 oz of liquid chlorine per 10,000 gallons of water. This amount should get the chlorine level to between 5 and 10 ppm.

Whats the Active Ingredient In Chlorine?

Sodium Hypochlorite

Whats the pH Level?

Between 12.3 and 12.9

Whats The Right Quantity Of Chlorine To Add When Winterizing?

If the water is clean and clear, then add about 3 oz of liquid chlorine per 1000 gallons of water while the pool filter is running. This should give you a chlorine level of about 3 ppm.

Weekly Chlorine Dose For The Swimming Pool

Once the chlorine value is at the right level, you can keep it at that level with chlorine tablets. Chlorine tablets are better than chlorine granules because the tablets dissolve slowly and keep the chlorine value constant.

Unfortunately, it is not easy to say how many chlorine tablets you should add to the swimming pool or how often you need to add them. The chlorine tablet dosage does not depend solely on the volume of the swimming pool. A lot of other things also play a role, such as:

  • The number of hours of sunshine and the UV valueThe reason being that the chlorine value is degraded by the UV rays of the sun.
  • Leaves and insects in the swimming poolLeaves, insects and other dirt cause the active chlorine to become exhausted
  • The number of hours swum per dayThe more swimming there is, the quicker the chlorine degrades
  • If the swimming pool isnt used much, be sure to check the water quality once a week using a water tester. If the pool is used more than 2 days a week, the water quality needs to be checked 2 to 3 times a week.

    If the pH value is good, check whether the chlorine tablet has completely dissolved or not. Once the chlorine tablet has dissolved, it is best to add 1 chlorine tablet per skimmer. Use these chlorine tablets for this. For a small inflatable pool, it is best to use these 20 gram mini-chlorine tablets. You can add one of these per 3 m³ of water.

    How Do I Add The Bleach To My Pool

    This is a question that most people require answers to because lots of pool stores do not suggest the use of simple chlorine. They recommend different products to sell their market. There are different forms of chlorine people add to their pool water. There are tablet chlorine and liquid bleach.

    The tablet chlorine works perfectly with other stabilizing agents to make the effect of the chlorine last longer in your pools. You can also use liquid bleach to clarify your pool water but you need to add a little amount of stabilizer to keep sunlight from killing the bleach molecules from your pool.

    Considering this, how much chlorine do you put in a pool per gallon?

    Whether you have a round ring-top pool or an in-ground pool, maintaining the chlorine balance in the pool prevents bacteria from growing in the water. The basic balance of chlorine to water is between 1 and 3 ppm, or 0.00013 ounces of chlorine per gallon of water.

    Furthermore, how much chlorine does a 3000 gallon pool need? 75 ounces per 3,000 gallons every week. Initially you will need stabilizer to protect the chlorine from the sun. This is added at a rate of one pound per 3,000 gallons of water.

    Likewise, how much chlorine do I put in a 1000 gallon pool?

    In our case, we choose a 1000 gallons pool. When shocking your 1000 gallons pool, you need to use 0.05 gallons of bleach to take the chlorine level to 5 PPM.After getting the volume, then multiply the volume by:

  • 7.5 for a rectangular pool.
  • 6.7 for an oval pool.
  • 5.9 for a-round pool.
  • Can you add too much chlorine to a pool?

    You‘ve put too much chlorine in your pool. Of course, too much chlorine in pool water can be dangerous. Exposure to over-chlorination can provoke asthma, lung irritation, and potentially skin and eye irritation. As well as being potentially bad for you, it’s bad for your pool.

    How Do I Add Bleach To The Pool Water

    1000 Gallon Pool Maintenance

    Most pool stores do not suggest using simple chlorine as a bleaching agent. They want you to use their products for adding bleach to the water. Most pool specialty stores will sell slow dissolving tablets of chlorine that when combined with other ingredients, stabilize the chlorine, so it releases slower, thus making it last longer. Although this may seem like the easier solution, stabilizing bleach greatly reduces the effectiveness it has on killing the microbes that need to be removed from your pool.

    The chemicals that are used in these tablets, such as dichlor, break down very slowly and difficultly and overall you cannot control how much of it is going into the water. Therefore, the new chlorine that is added via tablet will attack the dichlor and immediately be stabilized and will not attack the bacteria that you are trying to eliminate.

    The tablet is rendered effectively useless, and in a few weeks, the result will be a cloudy pool. More than likely, you will be stuck in a situation where the pool store will sell you additional expensive products that will not fix your problem. This is a costly mistake.

    Do not forget, however, when you add liquid bleach to a pool, you still have to add a small amount of stabilizer, so the sunlight doesnt eliminate the bleach molecules immediately. This step should not be too difficult since you are controlling the amount of stabilizer you should be able to prevent over stabilization.

    Perform A Cya Test Monthly

    A CYA test is very easy to do if you have the proper testing kit which including Cyanuric Acid Reagent. You will also need a tube that has a black dot on the bottom that you can see when water is added to the tube.

  • Fill the tube provided with water to the 7 ml line.
  • In the same tube add the cyanuric reagant until it reaches the 14 ml line.
  • Close the lid and shake the tube well for about 1 minute.
  • After shaken, pour the mixed tube into the other tube provided that contains the black dot little by little looking through the top of the tube. Once you can no longer see the black dot stop filling the tube. The current water level will have a number on the side and that is your CYA levels.
  • Monitoring your CYA levels monthly and your chlorine levels daily is key to maintaining a healthy and clear swimming pool when using bleach as your primary chlorinating method.

    What About Hydrogen Peroxide Can I Use Peroxide Instead Of Chlorine

    You might wonder if peroxide can be used instead of chlorine to sanitize your storage tank but this wont work.

    You can use hydrogen peroxide on cuts or abrasions to kill germs but it is not a good disinfectant for drinking water. Hydrogen peroxide is rarely used in drinking water as a stand-alone treatment process. Its a very weak biocide compared to chlorine or ozone.

    Its not approved by the EPA and other health authorities as a stand-alone disinfection treatment process. Hydrogen peroxide is great for removing odors and making water taste better but it is not useful for the disinfection of storage tanks.

    Sanitizing A Wading Pool With Chlorine

    Try to maintain a free chlorine level of 4.0 parts per million in a wading pool. This is a higher level than you would maintain in a larger private pool, but with no filter to help remove debris, you need a higher sanitizer level to handle the bather load and organic material.

    In a clean, freshly filled 500 gallon wading pool, add a quarter cup of unscented household liquid chlorine bleach to the water. Then, at the end of each day, test the water and add an additional 1/8 to 1/4 cup, depending on the reading. As it sits overnight, the chlorine will sanitize the water and breakdown organic compounds. Test the water the next morning before letting the kids use the pool to make sure it is in the safe range–at least 1.0 ppm, but not above 6.0 ppm. You can always lower a high chlorine level by adding more water.

    The easiest way to test the sanitizer level is with DPD test strips, available at any pool supply store and many hardware and building supply stores. Dip a strip into the pool and compare the color on the strip to the color chart provided with the strips.

    Gallons How Much Powder Ultra Shock To Use

    55 Gal. Drum

    Finally got a larger pool then we’ve ever had, but it’s still small. 475 gallons. Has a 300 gallon pump/ filter that came with it. I have no clue how to take care of anything like this without completely draining it, scrubbing it and re filling it every time and that’s a huge job with a bigger pool like this. I just want it to stay as clean as possible without having to completely drain the darn thing….while also being safe for my 3 kids under 7 years old. I went to a pool supply store and the lady sold me a $5 1lb bag of “Ultra Shock” powder. She said to get this kind because it is 97% chlorine instead of having added shellfish fillers that cloud the water. Anyway, it’s like trying to find a needle in a haystack getting an answer to this question, I guess because everyone else has bigger pools. This bag of chlorine powder has no directions on it for small pools and the lady said to use 1/2 pound for my pool. Does this sound right? I am really scared that I will over chlorinate and don’t want to poison my kids. I have no idea what I’m doing. HELP. Thanks guys

    Why Do You Need Chlorine For Your Hot Tub

    A hot tub can quickly become a cesspool of germs, bacteria, and other waterborne pathogens. This can be especially dangerous if more than one person uses the hot tub. Any water body that you use on a regular or even semi-regular basis needs to be kept clean at all times.

    Chlorine is a chemical that is made of hydrogen, sodium hydroxide, and ordinary table salt. It is used in swimming pools, jacuzzis, hot tubs, and other water bodies to sanitize and keep it bacteria and germ-free.

    One of the most important things to keep in mind when using chlorine is to use the correct quantity and not mix it with other chemicals. When this is taken care of, chlorine can be one of the most effective and safe disinfectants.

    So, how much chlorine do you need to put in your hot tub at home?

    Quick Dip: How To Shock Your Swimming Pool Using Liquid Chlorine

    Shocking your pool water is one of the keys to keeping your pool sparkling and ready to swim in. Failing to shock your pool water can lead to algae and bacteria build-up. This creates a swimming pool that is not only uninviting, but hazardous to pool patrons as well. Just because your water is clear, does not mean it is safe to swim in! This is why a high-quality pool testing set from LaMotte or Taylor is an essential part of every pool operators kit!

    Shocking a pool with liquid chlorine or a granular pool shock kills or inactivates pathogens and algae. Shocking will also oxidize other unwanted materials inhabiting the pool water. By raising the chlorine level in the pool to the correct level, and holding it there for the prescribed amount of time, this effectively disinfects the water. This article covers shocking your pool with two of the most popular shock products on the market today sodium hypochlorite and calcium hypochlorite .

    Preparing to Shock Your Pool

  • Know how many gallons of water your pool holds. Need assistance with this? Pentair has a handy online calculator that can tell you the volume of your pool.
  • Using your pool testing kit, check your current chlorine level. This is important if you are attempting to bring your chlorine level up to an exact level.

    In our case, we already know the volume of water our pool holds. And since our pools hold up to 10000 gallons of water, you will need to use ½ gallon of bleach which would raise the chlorine level by 5 ppm. If you want to raise the chlorine level of your pool by 2.5 ppm, you would need to use a quarter gallon of bleach for 10000 gallons of water. You can follow this same calculation to determine the level of ppm to raise your pool water but always ensure you test your water while carrying out this experiment.

    What Should You Do If You Add Too Much Chlorine

    To err is human! Maybe you added just a little too much chlorine to the hot tub, and now youre wondering how to fix it. Well, its relatively simple here is what you need to do:

  • Use A Chlorine Neutralizer
  • If you need to use the hot tub right away, consider adding a chlorine neutralizer. As the name suggests, it will neutralize the chlorine level in the hot tub, allowing you to use it without worrying about any side effects.

    Keep in mind that too much chlorine can be potentially harmful to the skin, eyes, and hair. Moreover, it is hazardous if ingested.

  • Add More Spa Water
  • This one sounds obvious, but it works. If you think youve added too much chlorine in the hot tub, add more spa water to neutralize it. You can drain some water from the hot tub first, adding more water once at least half the original quantity is drained.

  • Let It Reduce Naturally
  • Check the chlorine levels in the hot tub first. If you observe that the levels are higher than 3 ppm, but you dont plan on using the hot tub anytime soon, do nothing. The chlorine levels will stabilize naturally within a few days.

    Of course, if you plan on using the hot tub before that, it is best to opt for any of the other methods mentioned above.
