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.

1. 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:	does it turn the water BLUE,,, that is what I wont in my pool,,,Blue water
Answer:	it clears the water of any cloudiness. it does not turn the water blue. pool water will always reflect the color of your liner.
Question:	Will this work without shocking first
Answer:	Yes
Question:	Exactly what chemicals are in this product? Do I use it in addition to shock, muriatic acid, algecide.... or instead of
Answer:	This is not a product that replaces ANY pool chemical treatment. You still need your chlorine or other sanitizer, muriatic acid, CYA, Borax, algaecide, shock, etc. as usual. This enhances your usual maintenance chemicals. It does a great job of what I call clumping up small dust/dirt particles making it easier for the filter to remove them. It will not “turn you water blue,” but it does make the water crystal clear, and makes it sparkle. If you happen to have a liner with lots of blue in the pattern, it will make the water “appear” to be bluer, but all it does is remove fine particles, & makes the water crystal clear. I use it once a week, and dose after heavy rains. I’ve used it for 20 years, have tried others, but always come back to this.
Question:	I have an Intex Metal Frame Pool with a Saltwater Pump and Filter System. Will this product work with that type of set up
Answer:	Yes it stated on the bottle that it will work salt, and all types of filters/pumps.

Question:	Is it safe to ise in an inflatable pool without a pump system
Answer:	Yes for an indoor or covered spa. If it gets sun you want a stabilized product.
Question:	Is this safe for Vinyl Pools
Answer:	I had this issue the first time as well. Examine the red lock tab to see how it locks into place by falling into those holes. You need to pull up on that. Thing is, mine had already been pulled up. So instead of concentrating my energy on that I stood up, grabbed the top of the bucket with both hands and turned it left in order to open it. Simply grabbing it from the side with one hand was not enough the first time so you'll need both hands and grab from the top. Have another person hold the red tab up at the same time and it should open easily.
Question:	is this ideal to open an above ground pool for the season
Answer:	Yes, prices have changed (a lot )specially during summer.

"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!

In The Swim Chlorine-Free Oxidizing Pool Shock

Oxidizing swimming pool shock treatments are an essential aspect of opening and closing your pool. Oxidizing shock can also be used for weekly maintenance to help enhance your chlorine’s sanitizing efficiency. Chlorine-Free Pool Shock is one of the most versatile shock treatments on the market. It provides many benefits for virtually every swimming application.

Chlorine-Free Pool Shock will help eliminate chloramines (non-sanitizing chlorine) and allow the sanitizing chlorine to be more effective. Chlorine-Free Pool Shock is not only for routine maintenance, but is also great to use before and after you are expecting a heavy bather load.

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

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.

Adjusting and Balancing

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:	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.

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.

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.

1. 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.

User questions & answers

Question:	What is the active ingredient in the second part (the flocking agent
Answer:	If you’re dimensions are 18 ft. Diameter round pool that is 52 inches deep calculate the volume. But to get rid of the Green the box should be enough for two treatments. 2 bags of Shock, 1 bag of the flocculant. I think your volume would be under 8000 gallons.
Question:	Super green to blue has caused mine to be cloudy and green. What to do
Answer:	Yes. The sauna is (light weight) conveniently easy to fold down/dismantle and store away; when not in use. Fyi.. I have a large bathroom - and utilize my sauna on a daily basis since i purchased it; space is not a problem for me. Hope this helps.
Question:	What color is the powder supposed to be? Mine is brown
Answer:	This is a Far Infrared Sauna unit. Far infrared is better in many ways than full spectrum ones, and is the form most absorbable by the body. Far infrared are the same ones used in baby incubators in hospitals.
Question:	The box comes with 4 shock bags , how many bags do I need to add to my 18x52 inch pool
Answer:	Hi dear, you can put essential oils or herbs in the herbal box to physiotherapy, which can not be put in the steam pot. And the herbal box can be used to make steam spread broadly ( Note: Keep all the blowhole of the herbal box open then start using it. To avoid high temperature burns. Do not touch the herbal box when using ).
