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.

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. 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.
