    Pool Shock

    1. 4 weeks ago
      Easy and effective.
      Our pool was clear all summer with this shock. When we opened it this spring the water was perfectly clear. It is the best shock I have ever used!

      Bought to help in the management of our salt system pool after having the same recommended by the pool supply where a water sample was taken which is about 29 miles one way.

      Di Zap pool shock
      I have my packages of shock delivered right to my door don't have to run to pool store. My pool stays crystal clear and I have recommended to all my friends never have cloudy water again.

      Great results!
      This is our first year in our new house, and the pool had been poorly taken care of by the previous owners. The water was cloudy even after an almost complete water change and balancing. Then it turned green. Yuck! The pool shock we bought from our local pool store was not cutting it. Saw this online and figured it was worth trying. So happy we did! This in combination with Super Floc Out cleared the water right up. Now we use Super Pool Shock once a week to prevent new algae growth. I won't use anything else!

      Now that the summer has passed and I have some experience with this product I feel I can give an honest assessment. It works. The fine granules dissolve much better than other formulations at 68% or less available chlorine, and it has killed and oxidized anything I've ever found in my pool. Figuring the cost per unit of available chlorine shows that this product is cheaper even though it's priced higher. And you use less of it. Recommend that for maximum effect, powder shock should be broadcast ... read more into the pool after the sun goes down.

      Clear Water !!
      All of the products, especially the chemicals, are high quality and work great. My pool has been crystal clear for years. In fact, I replaced the pool this Spring and the start up kit brought the pH, alkalinity and chlorine levels right to where I needed them. Stop paying too much !! This company is fabulous.

      Great Product
      I love the fact that this product works so well with no fuss and muss, You dump the appropriate amount into the skimmer basket and let your filter do the rest. I have no problem maintaining the proper chlorine level and the filter does all the work. If you do run into any algae growth, a heavier dose of this product works well to kill it. No wasting money on costly algaecides. Reccomended doses for weekly shock are on the container too. I also love the safety lid. I have used many that are just ... read more so hard to open, this one just has you squeeze the tab and rotate. No more fighting the lid just to get to the chemical.

      Great product
      This is the same chlorine I use from our pool supply store. It works great and is really less expensive. Its a plus that it is delivered right to my door.

      Excellent Product
      I tried the instant chlorine and it works great. I put in my pool every eight days and the water is clean and a nice blue. I like it better then the liquid chlorine due to the fact that the containers always leek when I buy them at the hardware store.

      I LOVE THIS LITTLE BOTTLE
      AT FIRST I WAS SKEPTICAL ABOUT THIS POWDERED INSTANT LIQUID -- I NORMALLY BUY THE LIQUID CHLORINE TO ADD TO MY POOL, SO AT FIRST WHEN I OPEN THIS BOTTLE AND SAW IT WAS GRANULAR I THOUGHT WHY WOULD THEY CALL THIS "INSTANT LIQUID CHLORINE" BUT I HAD NO CHOICE AT THE MOMENT AND USED IT AFTER A LARGE POOL PARTY AND BOY WAS I PLEASANTLY SURPRISED...IT MADE MY POOL CRYSTAL CLEAR AND I'VE HAD TO USE SO LITTLE TO MAINTAIN ON A WEEKLY BASIS...SO I LOVE THAT I'M ACTUALLY SAVING MONEY. THANKS IN THE SWIM!

      A Must have for the hot summer months
      This product will clear out the nastiest water. In the south we get tropical showers that will require a lot of chlorine. This product is wonderful and gets the job done.

      Pool Opening
      I bought chlorine granules, shock and pool perfect. After the first initial shock, for the remainder of the year all I use in our pool is the granules and the pool perfect. It is crystal clear.

      Keeps pool sparkling
      The granulated shock is easy to use and dissolves quickly. We prefer this to the packaged shock. It works just as well and leaves less waste (plastic packaging). It's effective at keeping our pool water clear and sparkling. It looks so inviting!! We live out of the 1 day delivery zone, but we still received our order very quickly, which is important to me. I've ordered this product from In the Swim for several years now and have been very pleased, both with the product and the service.

      Fast accting
      I used many other pool shock products and was disappointed,some left residue that forced me to vacuum entire pool, then I had to wait for chlorine count to come down -usually 24 hours,when I switched to chlorine free shock I don't have to worry about these issues, this product does what it supposed to do with no "side effects" could enter the clear water in my pool several minutes after application

      Excellent chlorine free shock
      Excellent chlorine shock at a reasonable price.I like to use a non chlorine shock about every other week

      Great Product
      This is a great product.. I use to use chlorine shock and I would have to mix it in a bucket of water before adding it to the pool and it still made the water cloudy...After switching to the Chlorine-Free Pool Shock I don't have to waste my time mixing I just pour it directly into the deep end of the pool and walk away... My water stays perfectly clear and the kids can jump right in..

    In The Swim Knowledge Pool: Swimming Pool Shock

    In The Swim's Dr. Pool

    Shock Treatments for Swimming Pools

    Granular chlorine is a convenient way to sanitize and disinfect pool water. Used in small amounts, swimming pool shock can raise chlorine levels quickly for a pool found to be lacking. In larger amounts it will easily super-chlorinate or hyper-chlorinate pools for removal of cloudy water, chloramines, and disinfectant by-products. Most importantly, swimming pool shock quickly destroys pathogenic bacteria, viruses and microbes found in pool water. 


    The Many Types of Pool Oxidizers

    •  - Di-Zap Multi Shock is stabilized, and can be used daily in pools, spas and fountains without calcium build-up.
    •  - Pool Shock and Super Pool Shock from In The Swim is suitable for all purposes, sold in bags and buckets.
    •  - Non-Chlorine pool shock does everything that pool shock does, with exception to killing heavy algae blooms.
       

    The Many Uses of Pool Oxidizers

    •  - Restores clarity to cloudy pool water
    •  - Kills pool algae strains of all types
    •  - Sanitizes to destory bacteria of all types
    •  - Removes chloramines and other chlorine byproducts
    •  - Breaks down organic and non-organic matter, and bather waste
    •  - Raises chlorine levels quickly when found to be near zero
    •  - Removes stains on plaster, pebble and fiberglass pools
       

    How To Shock a Pool

    •  1. Clean the pool of debris before shocking a pool
    •  2. Balance the water chemistry and adjust pH to 7.2-7.4
    •  3. Each pound of pool shock can deliver between 7-9 PPM, per 10,000 gallons of pool water
    •  4. Add enough to reach a target threshold of 10, 20 or 30 PPM, depending on water condition
    •  5. Brush the pool, and run pool filter for 6-8 hours following super-chlorination
    •  6. Keep solar covers safely stored off the pool until high chlorine level subsides
    •  7. Check chemistry levels within 24 hours and adjust as needed, if chlorine is found to be zero, repeat shock treatment
       

    Pool Shock Treatment Tips

    •  - Always add chlorine to water, Never add water to chlorine
    •  - Always use the entire bag, Never store half-used bags of shock
    •  - Distribute the chemical around the pool, Never pour into the skimmer
    •  - Always adjust pH level to the low side, 7.2-7.4, where chlorine is more potent
    •  - Brush the pool after shocking, with a stiff pool brush, or a stainless steel bristled algae brush
    •  - Vinyl pools should pre-dissolve pool shock. Pour into a bucket of clean water and stir until dissolved
    •  - Sweep up any spills immediately, and add directly to the pool.
    •  - Never mix chlorine granules with any other type of chemical, or anything except water.
