13 best 3 inch chlorine tablets

3-inch chlorine tablets are a common chemical product used in the maintenance of swimming pools and hot tubs. They are a convenient and effective way to sanitize and disinfect pool water. Here is some information about 3-inch chlorine tablets:

  1. Chlorine Tablets: 3-inch chlorine tablets are solid, slow-dissolving tablets that contain a stabilized form of chlorine known as trichloroisocyanuric acid. This chemical is commonly used in pool maintenance because it releases chlorine into the water gradually, helping to maintain a consistent level of sanitation.

  2. Sanitizing Pools: The primary purpose of 3-inch chlorine tablets is to sanitize pool water by killing harmful bacteria, viruses, and algae. This helps ensure that the water is safe for swimmers and free from contaminants.

  3. Slow Dissolving: These tablets are designed to dissolve slowly over time, releasing chlorine into the pool water gradually. This slow-release feature makes them ideal for use in automatic chlorinators or floating dispensers.

  4. Stabilized Chlorine: The chlorine in these tablets is stabilized, which means it is less affected by the sun's ultraviolet (UV) rays.This allows the chlorine to remain active in the pool for a longer period, reducing the need for frequent reapplication.

  5. pH and Alkalinity: It's important to monitor the pH and alkalinity levels of pool water when using chlorine tablets. Chlorine can affect the pH balance of the water, so adjustments may be necessary to maintain the desired pH range for pool water (usually around 7.2 to 7.6).

  6. Dosage: The dosage of 3-inch chlorine tablets depends on the size of the pool and the current water conditions. Manufacturers typically provide guidelines on the product packaging for the recommended dosage.

  7. Safety Precautions: When handling chlorine tablets, it's essential to follow safety precautions. These tablets can be caustic, and direct contact with the skin or eyes should be avoided. Additionally, they should be stored in a cool, dry place away from other chemicals.

  8. Regulation: The use of chlorine tablets in pools is regulated in many regions to ensure safe water quality standards. Pool owners should be aware of and comply with local regulations regarding pool sanitation.

  9. Alternatives: While 3-inch chlorine tablets are a popular choice for pool sanitation, there are other chlorine products available, including granular chlorine and liquid chlorine. Each type has its advantages and may be chosen based on specific pool maintenance needs.

3-inch chlorine tablets are a convenient and effective solution for maintaining proper water quality in swimming pools and hot tubs. Proper usage and monitoring of chlorine levels are essential to ensure a safe and enjoyable swimming experience.

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.

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.

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.

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: Does this Work with salt water pool
Answer: I thought the idea of a salt water pool was that you didn’t need to use chlorine. So, I do not think that this is a necessary item.
Question: What is percentage of chlorine in each tab. Some brands have fillers
Answer: I do not know. I use a copper infusion solar device that puts copper ions in the pool and I use 2/3 less chlorine because algae can not grow in then copper environment.
Question: Is this 6 in 1 same label as pictured
Answer: Yes it is. We love this product I think you will too.
Question: Will my CYA levels rise with prolonged use
Answer: I used a floatron that puts copper ions to prevent algae growth, reduces the amount of chlorine usage by up to 75% and never worried about CYA levels. The copper probe also collects calcium and lowers hardness instead of changing or adding water when levels get too high.

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.

User questions & answers

Question: Can it be broken into halves
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.

Each 3" 8 oz. tab is individually wrapped for easier and safer handling, stabilized to prevent burn-off, and are slow dissolving to maintain a proper free chlorine level. Built-in clarifier produces crystal-clear water. Stain-inhibitor prevents and removes stains caused by metals and minerals.

Because your sanitizer has these additional chemicals built in, you will spend less money on pool supplies. For use in feeders or floaters - kills bacteria and controls algae, clarifies, prevents metal staining and corrosion, and reduces scale formation. Important notes: Shock your pool every week and also after heavy rain or heavy use to help keep your pool water properly maintained. Sunlight, rainfall, temperature, number of swimmers and frequency of pool use affect the rate of chlorine residual loss. Adjust cleaning and chemical maintenance accordingly. Use this product in an automatic feeder or floater designed for this product. Do not add other chemicals into the feeder or floater where this product is in use as a fire or explosion may occur. To avoid damage to pool surface or materials do not allow product to come in direct contact with these materials. Do not throw tablets directly into pool. Before using this product ensure all pool equipment is working properly. Adjust stabilizer levels to 40-100 ppm with a Stabilizer. Test the water’s pH, alkalinity, and calcium hardness and adjust to the correct level. Adjust pH to 7.4 - 7.6. Be sure to follow label directions when using other products as outlined in directions for this product. Check the free available chlorine level and adjust to 2-4 ppm by adding a granular chlorinating product. Start up and initial treatment directions: If water is cloudy or green, super-chlorinate pool with appropriate shock product until pool is clear. Add 16 ounces of this product (two tablets) per 10,000 gallons of pool water to feeder or floater and then test for the free available chlorine level (allow water to circulate at least 4 hours before testing). Adjust the feeder or floater following manufacturer’s instructions to establish a free available chlorine level between 2-4 ppm. When free available chlorine level is adjusted to 2-4 ppm, add an algaecide appropriate to your needs. For routine maintenance: Add 16 ounces of this product per 10,000 gallons of pool water per week, or as often as needed, to the feeder or floater to maintain a constant free available chlorine level of 2-4 ppm. Sunlight, rainfall, temperature, number of swimmers and frequency of pool use affect the rate of chlorine residual loss so check the feeder or floater often and refill as needed. Robelle 5-In-1 Swimming Pool Multi-Purpose 3" Chlorinating Tabs will kill bacteria, control algae, clarify water, prevent metal staining and corrosion, and reduce scale formation.

User questions & answers

Question: Do you still have to shock ur pool and use something for ph
Answer: Shock like normal, and I didn't have to use anything else for ph levels. Hope this helps.
Question: Hello i just started to use these tablets but the water is getting green. what will be the cause? do you have any idea? thanks a lot
Answer: It will turn green if you previously used the Baquacil brand of non-chlorine sanitizer or oxidizer.
Question: Are the tablets individually wrapped
Answer: Yes, individually wrapped.
Question: My alk and ph is low, will using these tabs help? or should i shock my pool and use these tabs
Answer: Neither these tabs or shock will have much impact on low ph and alkalinity. You should use ph up and alkalinity up treatments for those. These tabs are great at controlling the issues they are meant to be used for, though.
