12 best chlorine tablets

Chlorine tablets are commonly used in the context of swimming pools and hot tubs for water treatment and maintenance. These tablets are a convenient way to sanitize pool and spa water, ensuring it remains safe and clear for swimmers. Here's some information about chlorine tablets:

  1. Sanitization: Chlorine tablets primarily serve as a sanitizer for pool and hot tub water. Chlorine effectively kills harmful microorganisms like bacteria and algae, preventing the water from becoming a breeding ground for diseases.

  2. Types of Chlorine Tablets: There are typically two types of chlorine tablets available: stabilized and non-stabilized. Stabilized tablets contain cyanuric acid, which helps protect the chlorine from being broken down by UV rays from the sun. Non-stabilized tablets are used when cyanuric acid levels are already sufficient.

  3. Dosage: Proper dosage is essential for effective water treatment. The amount of chlorine tablets needed depends on the size of the pool or hot tub and the water's condition. It's crucial to follow manufacturer instructions and use a reliable chemical dispenser to control the release of chlorine.

  4. Storage: Chlorine tablets should be stored in a cool, dry place away from direct sunlight and moisture.Proper storage ensures the tablets remain effective and safe to handle.

  5. Safety: Handling chlorine tablets requires care. They are chemicals and can be hazardous if not used correctly. Always follow safety guidelines, such as wearing gloves and goggles when handling tablets, and keep them out of reach of children and pets.

  6. Regular Maintenance: Maintaining the proper chlorine levels in your pool or hot tub is an ongoing process. Regular testing of the water is essential to ensure that chlorine levels are within the recommended range. You can use test kits or electronic testers for this purpose.

  7. Water Testing Products: In addition to chlorine tablets, various water testing products are available to monitor pH levels, alkalinity, and other parameters to keep your pool or hot tub water balanced and safe for use.

  8. Cleaning Tools and Chemicals: Maintaining the cleanliness of your pool or hot tub often requires additional cleaning tools and chemicals. These may include pool brushes, vacuum cleaners, shock treatments, and algaecides to address specific water issues.

  9. Pools and Hot Tubs Supplies: The pool and hot tub industry offers a wide range of supplies and accessories to enhance the enjoyment and maintenance of these recreational features. This includes pool covers, heaters, filters, and more.

  10. Patio Lawn and Garden: Chlorine tablets and related products are commonly found in the "Patio, Lawn, and Garden" section of stores, as they are essential for the proper care and maintenance of outdoor pools and hot tubs, ensuring a safe and enjoyable experience for users.

Remember that proper pool and hot tub maintenance is crucial for safety and water quality. Always follow the manufacturer's instructions and consider seeking advice from professionals if you are unsure about any aspect of water treatment or maintenance.

User questions & answers

Question: Why would these cleaning tablets be recommended for a 14x36 pool that only holds 2,400 gallons
Answer: We are the manufacturer of HTH Super 3" Chlorinating Tablets and these are for pools of 10,000 gallons or more. For a 2,400 gallon pool we would recommend our HTH 1" Chlorinating Tablets. If you have any questions please contact us at 866-484-7665.
Question: Is this gonna blow up if I take it out of the pool, ppm is off the scale >10 and manufacturer is not answering their phone
Answer: No, the tablets do not 'blow up' when removed from water. If you're getting a high ppm reading you may be using too many tablets for your pool's size. Our pool is approximately 28,000 gallons, and we use two tablets in a floating container/distributor. We augment the tablets with once-a-week shock. If we have to add water (we live in the Florida Keys), or get a lot of rain we'll adjust the chemicals accordingly. Also, be sure you're running your pump and filter at least 8 hours a day for dispersal of chemicals.
Question: We just bought a 15 ft, 33 inch fast set pool. What would be the best to use
Answer: We are the manufacturer of HTH Super 3" Chlorinating Tablets and one of these tablets is for 10,000 gallons of water. For your size pool we recommend our HTH 1" Chlorinating Tablets. If you have any more questions please call us at 866-484-7665.
Question: My chlorine is really low, the ph and alkaline are high. What do I add
Answer: We are the manufacturer of HTH Super 3" chlorinating tablets. If your alkalinity and pH are too high you will need to adjust those by using HTH pH Down or Decreaser. For more information please call us at 866-484-7665 and we will be happy to help.

Question: How tall is the bucket
Answer: Your question seemed odd but did get me to measure the bucket! Exactly 18 3/8". Hope that helps. BTW, it is a fine product.
Question: were do you put the tablets
Answer: Just a comment, I'm no expert, but I have had my 39x22 foot in ground pool for 25 years this year. My skimmer became brittle after about 20 years of use putting 3-4, 3 inch tablets in the skimmer, hardly anything to worry about after 20 years. Also, I get that the chlorine sitting there when the pump is not running can concentrate the chlorine and yes the water does go into your pool filter but the initial corrosive water is not sitting in the filter it gets pumped right back out into the pool and less chlorinated water is coming in behind it. I have had the same pool filter and pumps since my pool was built 25 years ago and have no problems putting 3 inch chlorine tabs in the skimmer basket. I have only replaced the inside of the filter once because some of the sections were ripped, replaced the skimmer basket once after 20 years, and I just had it re-plastered 3 years ago. Like I said before, I'm no expert this is just my experience. Now if someone can tell me how to get rid of the pool.....
Question: is there an expiration date for these tablets
Answer: no expiration ,just keep closed tight and dry. work better than other brands i have used .
Question: How many tablets are in this bucket
Answer: The description says that there are approximately 114 tablets per bucket.

These industry-leading chlorine tabs have 90% available stabilized chlorine for long lasting sanitizing power. floaters or automatic feeders. These industry-leading chlorine tabs have 90% available stabilized chlorine for long lasting sanitizing power.

How to use chlorine tablets:

Add 1-2 chlorine tablets to every 10,000 gallons of pool water.

For best results, we recommend testing the chlorine level once per week.

Increase dosage after heavy use, rain or warm temperatures.

Pool Care and Maintenance

It is important to maintain your pool/spa to keep it clean and healthy all year round. Good habits, such as cleaning your filter or emptying your skimmer basket, will ensure that your investment is protected for years to come. But most importantly, you and your family will be able to enjoy the swimming pool or spa each season.

Water Testing

Testing the water weekly or bi-weekly, depending on use and outside variables, helps keep your pool/spa water healthy. Utilizing a DPD or OTO reagent-based water test kit, test strips, or digital testing will help you monitor the pool or spa water chemistry.

Adjusting and Balancing

Adjusting and balancing your pool or spa water chemistry ensures that you will get the most out of the swimming season. The benefit of having good pH and Alkalinity levels is that it will increase the ability of your main sanitizer to kill bacteria. Balanced pool water chemistry will also reduce chemical and maintenance costs. Balanced pH and alkalinity help prevent corrosion and scale formation on the interior pool surface and surrounding equipment.

Sanitizing

There are many different types of sanitizers used in various pool and spa environments. Clean and healthy water starts by establishing a proper residual chlorine level with shock or concentrated granular chlorine. The most common way to maintain a proper chlorine level is by using trichlor chlorine tablets in either a floater or chemical feeder. Applying these steps to your normal maintenance plan will ensure the elimination of non-living organic contaminants, bacteria, micro organisms, and algae making your water safe to enjoy.

Pool Fun and Safety

Now that the water is properly balanced and sanitized, it’s time to get in there and have some fun! We recommend enhancing your outdoor living environment with games, floats or loungers, toys, and accessories. Get creative!

Safety is of the utmost importance, and there are many ways to help make your pool/spa safer. Having a life ring buoy, a shepherd's hook, depth markers, coast guard-approved life preservers, door and water alarms and having your local aquatic environment safety regulations on-hand will ensure a fun and safe environment for your family.

Treatment

Even after all your preparation, sometimes life happens and your pool or spa can get away from you. In those moments, we need to start back from the beginning with testing of the water. Now that you have a clear idea of the current readings, your next steps will depend on the type of symptoms your water is presenting. This may include an issue such as algae (green, yellow, black, etc.), cloudiness, living organics, debris, and other water conditions.

User questions & answers

Question: Are these good for saltwater pool
Answer: Yes, they can be helpful. Saltwater pools use a chlorine generator but in my case there is insufficient chlorine generated (even though it's near 100% capacity). I had two or three tablets to the skimmer every few weeks and it helps maintain a good disinfectant level.
Question: Do they work in a automatic chlorine dispenser
Answer: Yes
Question: Pool nOOb here. I have a saltwater pool with automatic chorine generator. Is this the stabilizer I need to add to skimmer baskets
Answer: Cyanuric acid is the stabilizer you're thinking of. This has it but there are other products available that are just cyanuric acid without the chlorine.
Question: I have always used sticks because they won't dissolve unless water is flowing over them. Do these work the same way
Answer: I have used 3” tabs in my floating duck chlorinater and my levels are always consistent. The tabs dissolve faster during the summer months never have had a problem with them

User questions & answers

Question: Is the contents just chlorine or does it contain an algacide too
Answer: It is just chlorine.
Question: Does it have an expiration date
Answer: Not that I could find. Store in a dry, cool dark place. I bought 2 pounds originally and now my remaining must be well over 2 and 1/2 years old and they are perfect. A good product, good price. I have a small spa and it sparkles. Good luck, Lyn
Question: how many tablets does this container have
Answer: There are exactly 150 Tablets per four-pound bottle. I took a new bottle outside, poured it out into a box and counted. There were 149 whole ones, and one mostly pulverized, whose powder required that the box be thrown away in a sealed trash bag. I do not recommend any further studies be conducted in a similar manner. The odor was staggering, and burned the airways of all nearby. For those interested in using these tablets as refills for the Fluidmaster 8302 cartridges, at $16.39 per two-pack of Fluidmaster 8302 refills, this is equal to $409.75 worth of Fluidmaster refills as of 6/18/2017. Plus, you get the virtuous feeling of having recycled the cartridges. However, if you are at all odor sensitive, be aware that the refilled cartridges smell MUCH stronger than the original bleach cartridges. We could not tolerate the smell, and had to throw the refilled cartridges away.
Question: How many tablets come in this 4 lb container? And how many tablets and how often would I use them in an 8X30 Intex above ground pool
Answer: I'm not sure how many tablets are in the container, but plenty. I use 3-4 tablets in my pool every other day but I have a 20' x 48" pool.One container lasts me about 3 months. It also depends on the weather, cooler I don't seem to need as much. Just trial and error. Seems to keep the chlorine levels just about right. Hope this helps.

User questions & answers

Question: how many tabs in the 8 lb. bucket
Answer: A lot, packed in individual clear plastic bags of about 10 each.
Question: Can these be used in a kiddie pool which holds 125 gallons
Answer: I use it in a small hot tub and the coloring us very strong. I personally wouldn’t use it in a kiddie pool as I wouldn’t want that to use such a strong chemical with small children.
Question: How many tablets are in the bucket
Answer: They come in individual baggies with about 59 tablets in a baggie, I don't remember how many I've used already so there is about 25-30 baggies in the bucket. It's 100 pounds I like the individual baggies (they don't take much extra space) because I've bought chlorine before where you have to scoop it out this is much more easier. I think it's a good deal.

User questions & answers

Question: Every week I have to add acid to my pool to decease the pH. Will these tablets keep the pH from increasing
Answer: It is 86% baking soda, which will increase you pH. I would discontinue using a chemical that reduces your pH unless you are trying to raise pH. Pools only need three chemicals: Chlorine, Clorine stabilizer (CYA) NO more then 30ppm, and muriatic acid. Boric acid can be used to stabilize your pH as well, which will raise you pH, but as it is an acid not as much as baking soda will.
Question: Can i just drop the tablets in my pool or do i have to use a dispenser? i only have one dispenser that i put the cholorine tabs in. we have an 18x
Answer: It's baking soda. It's technically one of the chemicals that is fine to drop in the pool. I would just assist it with a brush maybe.
Question: Can you use this with a saltwater system
Answer: The directions on the container say "use with your chlorine"... That being said, I don't know if they are compatible/useful in a saltwater system.
Question: Is this jut baking soda
Answer: The product is mostly baking soda with water clarifier added in. The product does 3 things: increases pH, increases Alkalinity and adds clarifier to your pool water. I use this product with my outdoor pool which holds about 28,000 gallon and have been very happy with it. I add about 1 tablet of this per 4 tablets of 3 inch chlorine tablets that I put into my chlorinator. If you monitor your pool chemistry you could also periodically just add a tablet(s) when your pH and Alkalinity levels get low in your pool.

Answer: We are the manufacturer of HTH Super 3" Chlorinating Tablets. It would be unsafe to break the tablets. For more information please call us at 866-484-7665 and we will be happy to help.
Question: Why is shipping so long
Answer: Shipping has been updated
Question: Is this safw to use for small kiddie poola
Answer: These are way too large and strong for a kiddie pool. Buy a 1” floater and 1” tablets instead and only put 1 or 2 of them in it and check your chlorine levels daily. Also, the person who said you need a filtration system for these to work is right. These are way overkill for a kiddie pool!! If yours doesn’t have a filtration system, I would just stick to dumping it and refilling every couple days. Hope this helps.

Kills Algae and Bacteria

Algae can turn pool water green. HTH Super 3" Chlorinating Tablets destroy algae and bacteria to keep the water looking blue.

1 Tablet Works for up to 1 Week

This easy-to-use chlorine tablet dissolves slowly and effectively to sanitize your pool. One tablet keeps working for up to one week per 10,000 gallons.

Formulated to Prevent Chlorine Loss

HTH Super 3" Chlorinating Tablets are formulated with cyanuric acid (CYA) to help protect against chlorine loss, and they contain built-in algae protection and clarifier.

1. Test and Balance pH Levels

First, make sure the pH of the water is balanced. If the pH is too high or too low, the chlorine sanitizer won’t work as effectively. The ideal pH range is between 7.2 and 7.8.

2. Proper Sanitization Requires Circulation

HTH Super 3" Chlorinating Tablets release chlorine slowly. Run your pump at least 8 hours per day (or night) to ensure your water is properly sanitized.

3. Apply to Feeder, Floater or Skimmer

Place one tablet in pool feeder, floater or skimmer per 10,000 gallons of water every week or as often as needed to maintain a chlorine residual of 1-4 ppm. Do not add directly to the pool as this can cause damage to pool surfaces.
