Boost Chlorine

Chlorine sanitizes your pool to remove bacteria and other hazardous contaminants to keep water clean. Use HTH Super Shock! Treatment to restore chlorine levels that have been depleted by the sun, rain and heavy use.

Kill Bacteria & Algae

Low chlorine levels, poor water circulation and warm weather can encourage bacteria and algae growth. Rid your pool of black algae, mustard algae and green algae and prevent regrowth by shocking your pool once a week. Don’t forget to brush the floor and walls of the pool.

Keep Water Clear

The fast-dissolving formula found in HTH shock treatments acts quickly to restore clarity to your water so you can be back in the swimming pool within 24 hours. Plus, the treatment won’t overstabilize your pool or fade your liners.

Test pH Levels

Dip an HTH Multi-purpose 6-Way Test Strip (sold separately) into the water to measure total alkalinity, pH, free available chlorine (FAC), calcium hardness, and cyanuric acid (CYA) or stabilizer. Balance water, and adjust alkalinity and pH levels, where applicable.

2. Apply Directly to Water

Before handling any chemicals, put on protective gloves and goggles. During evening hours and with the pump running, broadcast the HTH Super Shock! Treatment evenly over a wide area in the deepest part of your pool.

3. Wait & Test Chlorine Levels

If granules settle along the bottom of the pool, use a brush to disperse until granules are dissolved. Once free available chlorine levels are between 1 and 4 parts per million, your pool is ready to use again.

In The Swim Pool Shock Treatment

Swimming pool shock treatments are an essential aspect of spring pool opening but can also be used to give your pool a quick chlorine boost. Pool Shock is our most popular and versatile pool shock treatment, used to kill algae and bacteria and remove micro-contaminants that make pool water cloudy.

Use our Pool Shock to kill visible algae blooms and invisible bacteria, which could cause illness to swimmers. Your daily chlorination of the pool will kill most pathogenic bacteria, viruses and microbes, however to be sure that the water is sanitary, it is good practice to 'shock the pool', or super-chlorinate the pool every few weeks, to oxidize everything in the water, especially the invisible germs that may be harboring in the water.

Reliable & Easy to Use

In The Swim Pool Shock is our most economical chlorine shock treatment for pools, sold in convenient 1 lb. bags. Powerful formula contains 99% calcium hypochlorite in a powerful 68% available chlorine formula. Granular chlorine Pool Shock is used for a variety of purposes to sanitize and disinfect pools, spas and fountains. Easy to use Pool Shock effectively treats 10,000 gallons of pool water per bag.

Kills Algae & Bacteria

Use our Pool Shock to kill visible algae blooms and invisible bacteria, which could cause illness to swimmers. Your daily chlorination of the pool will kill most pathogenic bacteria, viruses and microbes, however to be sure that the water is sanitary, it is good practice to 'shock the pool', or super-chlorinate the pool every few weeks, to oxidize everything in the water, especially the invisible germs that may be harboring in the water.

Super Chlorinate

One pound of In The Swim Pool Shock will raise free chlorine levels in a clean and balanced pool to 9 ppm, per 10,000 gallons of pool water. Pools with excessive debris, algae, suspended particles or heavy sunlight will need a proportionally higher dose of pool shock, to compensate for such factors. A double or triple dose is often required for poor water conditions such as spring openings, bacteria contamination, or severe algae blooms.

User questions & answers

Question:	Is it ok to use this everyday to maintain our swim spa's (2500 gallons) chlorine level? I have to add about 2-3 ozs/day
Answer:	3" dia. by about 1.5"thick. the amount in a 50 lb. bucket I never thought about....I would say at least 100 of them...plus or minus...
Question:	I feel dumb, but I can't figure out how to open this bucket. I've tried jostling the red tab and turning but to no avail. Any tips
Answer:	Yes, i use it in my salt water pool, one bag a week
Question:	Haven't ordered this in awhile. Do I have it right that the price for a single 50-lb tub has doubled in the last 6-8 months
Answer:	I just sprinkle around pool
Question:	How large are the tabs (3 inch or smaller) and how many tabs in each 50 lb bucket
Answer:	Good question: I reviewed several sources and found the answers to be complicated. My opinion is that Granular calcium hypochlorite contains 65 percent of available chlorine. Therefore, if you are currently using sodium hypochlorite (12%), then you can make an equivalent stock solution by mixing 1.5 pounds of granular calcium hypochlorite to each gallon of water in the stock solution tank. Source of information http://www.eng-tips.com/viewthread.cfm?qid=93148 The solid form (Calcium Hypochlorite) seems easier to use which is why I purchase that one. Additionally, the cost per unit of chlorine from the calcium hypochlorite seems to be less expensive. Again, sources of information show differing numbers including the amount of free chlorine released from each unit. It may be a good idea to try each one then test the resultant solution for the amount of available Chlorine.

In The Swim Cal-Chlor Chlorine Granular

Swimming pool shock treatments are an essential aspect of spring pool opening but can also be used to give your pool a quick chlorine boost. Cal-Chlor Chlorine Granular is a strong pool shock treatment which is used to kill algae and bacteria as well as other harmful water contaminants. It is also a great shock to use for Spring pool openings.

Use our Cal-Chlor Chlorine Granular to kill visible algae blooms and invisible bacteria, which could cause illness to swimmers. Your daily chlorination of the pool will kill most bacteria and other contaminants. To be sure that the water is completely sanitary, it is best to super chlorinate by shocking the pool every few weeks. Doing this also allows you to oxidize everything in the water, especially the various contaminants that may exist in the water.

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.

Answer:	It’s dichorine which is better
Question:	How fine are the granules? Some products are almost dust like and blow in my face when putting it into my level spa. Sand like would be fine
Answer:	I looks like granules are sand like but it also looks like there is dust in the bucket as well. If you're worried about it blowing back in your face I'd say it seems possible

Answer:	If this product contains ACL? It in then name itself. Yes it does.
Question:	Do you recommend using a floater or throwing straight into pool water will be ok
Answer:	I use this for my hot tub and it dissolves fast I would suppose it will be fine in your pool
Question:	How long will 50lbs last

Answer:	Every bucket I have purchased had a measuring scoop in it. Very convenient

Swimming pool shock treatments are an essential aspect of spring pool opening but should also be used to give your pool a quick chlorine boost. Super Shock is the most popular and versatile pool shock treatment available that is used to kill algae and bacteria and remove micro-contaminants that make pool water cloudy. Use Super Shock to kill visible algae blooms and invisible bacteria, which could cause illness to swimmers. Your daily chlorination of the pool will kill most pathogenic bacteria, viruses and microbes, however to be sure that the water is sanitary, it is good practice to 'shock the pool', or super-chlorinate the pool every week. Shocking your pool eliminates any contaminants in the water, especially the invisible germs that may be harboring in the water. It is also smart to "Oxidize" your pool water on a weekly basis with Oxidizing shock. "Oxidizing" your pool water on a weekly basis burns off "chloramines" - or spent chlorine cells - allowing the newly introduced chlorine to work at 100% efficiency. It also eliminates all of the contaminants that your chlorine and chlorine based shock have killed in the pool water - helping ensure a safe, clear pool!

• Powerful chlorine shock treatment that is great for regular maintenance
• Quickly eliminates algae, bacteria, and other harmful contaminants from your pool water

User questions & answers

Question:	Where are the shocks made

Question:	What is the shelf life of this product
Answer:	all pool shocks shelf life is normally one hear; then slowly their strength decreases. at what rate, dont know. however, i never had any issues using 2-3 year old shock.

• CLEAR WATER FOR SAFE SWIMMING - Swimming in crystal clear water does not mean your skin has to suffer. The granular chlorine is 99% sodium diclor making a relaxing swim not as harsh.
• LONG LASTING - Dichlor resists UV light, lasting longer than other types of chlorinating supplies due to built in stabilizer for your swimming pool, hot tub, or spa.
• DISSOLVES QUICKLY - Add 1 oz of this cleaning chemical to your pool for every 5,000 gallons your pool contains, daily for the best quick water treatment maintenance.
• FEWER CHEMICALS NEEDED - Our dichlor is pH neutral, meaning less chemical adjustments to be made by you! This pool chlorinator acts as a sanitizer, pool algaecide, and disinfectant. This granular chlorine dissolves in a 4-foot column, so there is no need to worry about bleach damage on your pool liner as with chlorine tablets.
• TRUSTED POOL SUPPLIES - Rx Clear is the best choice for swimming pool accessories and pool chemicals and supplies.

User questions & answers

Question:	I used this product and my cya level went so high that i had to replace my pool water. i assume this is stabilized chlorine? if so how much
Answer:	The ant trap creates a moat of water that ants cannot crawl/swim through to get to the feeder...gnats fly so they would still be able to get to the feeder. As an ant barrier, this product works great for my hummingbird feeders and oriole feeder. I have 6 of these traps! Would highly recommend for ants and other crawling bugs. Good luck with the gnats!
Question:	Is it fast dissolving so I can scatter it directly in the pool
Answer:	Because vendors are hoping you won't be paying attention
Question:	can it be used to shock the pool?how
Answer:	I spray mine before each season. Only reason I bought nee units because the color had faded after 8+ years of use.
Question:	So I can use this instead of chlorine correct
Answer:	I regret that I am not able to confidently answer your question. I'd have to disassemble the unit and I don't have an old one to examine. It could be that you could soak ithe unit in the Permethrine. Good luck!

User questions & answers

Question:	how long ship
Answer:	My only problem with shipping is that you have to be present for delivery. We wound up having to pick it up at our local warehouse for fedex.
Question:	Can I use this for waste water treatment
Answer:	I am no chemist, but it does clear up the pool when it turns green. So I suppose that you could, but I really do not know. Best of luck.
Question:	Does it contain stabilizer, or is it not stabilized
Answer:	I bought this product because calcium is not supposed to have stabilizer, but after five applications, my CYA reading is increasing. I am not happy.
Question:	Is it a loose product and if so dose it come with a measuring cup for the required 1lb add
Answer:	It is granular and comes with a measuring cup. I can't vouch for the accuracy of the cup as I assume it measures volume rather than weight but it could account for that.
Question:	Can this be used in salt water pools
Answer:	Yes, i use it in my salt water pool, one bag a week
Question:	Does this really need to be diluted in water before adding it to your pool or can you just sprinkle directly into pool water (all around of course
Answer:	I just sprinkle around pool
Question:	So what's the difference between sodium and calcium hypochlorite ? Is 1pack of this is stronger than a bottle of 12.5pc sodium
Answer:	Good question: I reviewed several sources and found the answers to be complicated. My opinion is that Granular calcium hypochlorite contains 65 percent of available chlorine. Therefore, if you are currently using sodium hypochlorite (12%), then you can make an equivalent stock solution by mixing 1.5 pounds of granular calcium hypochlorite to each gallon of water in the stock solution tank. Source of information http://www.eng-tips.com/viewthread.cfm?qid=93148 The solid form (Calcium Hypochlorite) seems easier to use which is why I purchase that one. Additionally, the cost per unit of chlorine from the calcium hypochlorite seems to be less expensive. Again, sources of information show differing numbers including the amount of free chlorine released from each unit. It may be a good idea to try each one then test the resultant solution for the amount of available Chlorine.
Question:	Is this safe for vinyl pools
Answer:	buy a floating dispensor for 3 inch tabs,buysome tabs. next the important thing,a test kit,a simple 2 test kit will do for what you have.just test chlorine and ph, ph takes a week or so to settle down to a good reading.don't even need to test for first week. after you get some good reading then tell me what they are and I will help you to adjust it. its simple with a pool your size. run filter 6-8 hours a day.most important and don't forget this!!! have fun!!!!! depending on how your ph goes will determind what chlorine to use,there is no straight chlorine,it is all bonded to another element ,which element you want depends on your ph reading.

In The Swim Pool Shock Treatment

Swimming pool shock treatments are an essential aspect of spring pool opening but can also be used to give your pool a quick chlorine boost. Pool Shock is our most popular and versatile pool shock treatment, used to kill algae and bacteria and remove micro-contaminants that make pool water cloudy.

Use our Pool Shock to kill visible algae blooms and invisible bacteria, which could cause illness to swimmers. Your daily chlorination of the pool will kill most pathogenic bacteria, viruses and microbes, however to be sure that the water is sanitary, it is good practice to 'shock the pool', or super-chlorinate the pool every few weeks, to oxidize everything in the water, especially the invisible germs that may be harboring in the water.

Reliable & Easy to Use

In The Swim Pool Shock is our most economical chlorine shock treatment for pools, sold in convenient 1 lb. bags. Powerful formula contains 99% calcium hypochlorite in a powerful 68% available chlorine formula. Granular chlorine Pool Shock is used for a variety of purposes to sanitize and disinfect pools, spas and fountains. Easy to use Pool Shock effectively treats 10,000 gallons of pool water per bag.

Kills Algae & Bacteria

Use our Pool Shock to kill visible algae blooms and invisible bacteria, which could cause illness to swimmers.

Super Chlorinate

One pound of In The Swim Pool Shock will raise free chlorine levels in a clean and balanced pool to 9 ppm, per 10,000 gallons of pool water. Pools with excessive debris, algae, suspended particles or heavy sunlight will need a proportionally higher dose of pool shock, to compensate for such factors. A double or triple dose is often required for poor water conditions such as spring openings, bacteria contamination, or severe algae blooms.
