    Pool Shock

    1. 2 years ago
      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!

      Cloudier than other brands
      By chance I had a few bags of ITS Super Shock and a few bags of Ultra Shock made by N. Jones Company. I noticed when putting them in the pool the ITS shock made the pool cloudy and the other did not. I have no idea why, but I would prefer the other shock.

      Easy to use
      The best thing about this product is that you can add it directly into the water! the last shock I had you had to mix it and then pour it in. I love in the swim!!

      Great Dissolving Qualities
      In The Swim granular chlorine is the only one we will use in our pool. Coupled with occasional Super Pool Shock treatments throughout the season, the pool stays crystal clear. A great combination, and one that we have counted on for over ten years.

      exactly what I needed
      I had a to treat my pool for white water mold several times of the last 3 years which required multiple applications of high amounts chlorine based shock. The chlorine shock that I used was stabilized and the end result included my pool water registering a high level of stabilizer. I needed to find a chlorine product that did not include a stabilizer and this product was EXACTLY what I needed.

      Great product
      My CYA was getting high so I needed something to add chlorine/shock my pool that wouldn’t increase it. This is exactly what I needed! It works well and my pool is very clear.

      Hreat Stuff!
      We have been getting all of our pool products from In The Swim for several years. Everything does exactly what they are supposed to do. The Shock and this product are awesome. We have a 44k gal inground pool. Its a struggle to keep the levels up due to size and sun. This product gets the water back in shape over night!! Thank you In The Swim.

      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..

      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

      Great for smaller pools
      I've been using this product for years in a vinyl lined 9,700 gal. pool. Regular chlorine shock runs the chlorine level up too high for swimming for over 24 hours, but with this product we can swim the next day. (I usually shock late in the evening.) Also, it doesn't bleach the liner. But if the pool gets infected with algae, you need chlorine shock.

      Great purchase! I used it to shock the pool and the next day all the algae were gone

      Eliminated My Yellow Algae
      We have a 15,000 gallon 16 year old concrete pool that needs to be refinished because it has corroded over the years from chemical use which creates the perfect environment for algae growth. We had mustard algea pretty much everywhere with a concentration on the sides and steps. The Super Algeacide and Super Shock totally eliminated it! It took a lot of elbow grease (brushing and vacuuming), but after a couple days and almost the entire bottle of Super Algeacide over the course of thee days, it ... read more is gone and has remained gone! Last summer I spent much more $ at our local pool supply store buying products to eliminate the mustard algea. Great product and great price!

      Good Only When Needed
      I only use a 68% calcium chloride when opening my pool and after adding water when back washing my sand filter to keep the hardness in check. My local pool store sells bags of this for $0.99/lb. Works great as a shock but even after mixing and pouring in front of returns, the water remains cloudy. Muriatic acid brings the PH back in line and removes the cloudy look. The acid adds to the expense and its another chemical I don't like to store with young children. If you test your water regularly ... read more and keep everything balanced there is no need to use a shock. During the summer I only add 6% liquid chlorine that the local pool store sells for $0.99/gallon. Liquid chlorine will not cloud the water and has no other ingredients to upset my pools chemistry.

      Pool shock
      This pool shock worked okay I use it for opening my pool in spring for some reason that no one can tell me why it takes cases and cases of liquid shock to get the water to read any chorine on the test strip so this year I mixed the shock some liquid some granular it still took a whole lot of shock

    Shock Treatments for Swimming Pools

    Granular pool shock treatments are a convenient way to sanitize and disinfect pool water. Used in small amounts, our pool shock can raise chlorine levels quickly for a pool found to be lacking. In larger amounts, pool shock will easily super-chlorinate or hyper-chlorinate pools for removal of cloudy water, chloramines, disinfectant by-products, and all types of bacteria, virus and microbes found in pool water. 


    The Many Types of Pool Shock

    •  - 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 for Pool Shock

    •  - 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

    Where's the Lithium Shock?

    Lithium pool shock is no longer available, due to a worldwide shortage of the raw element Lithium. Lithium prices have risen steadily over the past ten years, driven by high demand for Lithium, used in Lithium Ion batteries from everything from wrist watches to electric vehicles. The price increases in 2016 finally reached a tipping point, where manufacturers stopped producing Lithium Hypochlorite. The best substitute for Lithium pool shock is non-chlorine pool shock, in terms of having the most similar features. Calcium Hypochlorite can also be used in place of Lithium Hypo as well, however it does not dissolve as rapidly; pre-dissolving is recommended for vinyl pools.


    Should I Pre-Dissolve Pool Shock?

    When using chlorine pool shock in a Vinyl pool, it is recommended to pre-dissolve the granules in a bucket of water before adding to the pool. Plaster, pebble and fiberglass pools can pour or broadcast directly into the pool, using a pool brush afterwards to help distribute the granules. To Pre-Dissolve pool shock, pour 1 or 2 bags into a clean 5-gal bucket that has been 3/4 filled with pool water. Stir for 60-90 seconds until completely dissolved, and then pour along the edge of the pool. If any remaining granules fall into the pool, use a pool brush to help them dissolve. 


    How Do I Shock My 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 will deliver between 7-9 PPM, per 10,000 gallons of pool water
    •  4. Add enough shock 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 shock treatment
    •  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 shock to water, Never add water to pool shock
    •  - Always use the entire bag, Never store half-used bags of shock
    •  - Always distribute the shock around the pool, Never pour into the skimmer
    •  - Always shock a pool with a pH level on the low side, 7.2-7.4, where chlorine is more potent
    •  - Always brush the pool after shocking, with a stiff pool brush, or a stainless steel bristled algae brush
    •  - Always rinse out your shock bags in the pool, and allow them to dry before disposing in the trash
    •  - Always sweep up any shock spills immediately, and pour into the pool. Never mix chlorine types.
