    Pool Shock

    1. 2 months ago
      So far, so good
      Had too much CYA from “stabilized chlorine” and needed to lower, this product gave me chlorine without CYA, and I’ve had seen my CYA lowering since using it (have had to pump pool few times due to rain) but I use about 6-8oz every other day for 20k gallons, and have had no issues. Was worried about price paid and thought of it not lasting long, however, I’ve hardly put a dent in the bucket, and probably could make a full season last from one bucket at the rate I’m using currently

      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.

      Great value, even better when on sale!
      I have a 60,000 gal in-ground in the middle of the woods in the northeast... constant debris, wildlife, etc. making its way into the pool on a daily basis makes keeping the chemistry balanced and inhibiting algae growth a constant struggle. Previously I was running to the local pool store and picking up liquid chlorine 15 gals at a shot to balance and shock the pool in conjunction with my In The Swim Tri-Chlor tablets in my 2 chlorinators. I decided to give the Calcium Hypochlorite ... read more Sanitizing Granules a shot when I saw the 50# container on a great sale price while reordering my Tri-Chlor tabs. My first shock treatment only took 6# of granules, where as I typically would need 10-15 gallons to reach the same effect. Cost to product ratio was far better with the Granules, plus I can store the 50# much safer in a smaller space than the equivalent in liquids with fewer trips. Not to mention I'm far less likely to get a chemical burn from splashback or accidental spillage with the granules. From my initial experience, I estimate that I will continue this method over liquid chlorine from now on.

      Just what I was searching for!
      I had been buying this type product locally but for some reason every place stopped carrying the non chlorine shock. It is what I need for our salt system from time to time depending on weather and the location of our pool. This was the perfect buy for us.

      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 on my skin
      I have a fair skin complexion making me highly susceptible to chlorine. I originally thought I could get by with just using this and not using Chlorine in my pool. Nope don’t make that mistake, that was a rookie move I had made many years ago until I found my pool having mustard algae and a huge chlorine demand. Wound up forking out a lot of money to bring my chlorine levels back up to par, but I paid for the lesson. So while you still need chlorine to effectively balance your pool, this is ... read more great for weekly shock treatments and upkeep which is easier on my skin then standard chlorine treatments.

      Clouds Water
      This product worked better than the HTH shock that I also purchased however they both do not dissolve like they claim to and they also make the water cloudy. Will probably not order again. I prefer the In The Swim Super Shock...never had a cloudy issue with that product.

      Best shock thay I have ever used.
      I got a box of 12 bags & I'm glad I did. It does more than shock. I have a fibreglass pool and had trouble with staining when I shocked with a different brand, it also dissolves quickly

      ALGAE GONE
      I started to get Algae on the walls of my pool due to excessive heat and rain - after I used the Algecide - I put three of these Dizap packets in and shocked the sht out of my pool - its crystal clear now!

      Excellent and quick-acting!
      Excellent and quick-acting! It's amazing and quite miraculous how fast this stuff counters a pool suffering from algae and any level of greenness.
    2. 2 months ago
      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!!

      Just What I ordered
      Just what I ordered. I like using calcium based shock to help PH control. Good price.

      Great Value and results
      Bought the Shock cheaper than i can find anywhere else. Also purchased the Algecide. Pool has been CRYSTAL clear ever since.

      Best I've found!
      We have used In the Swim Shock for many years now. It's always the best value, and works every time.

      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.

      Excellent product
      I have had great results with this product. Well worth the money.
    3. 1 year ago
      Excellent product
      Great product for quick clorine adjustments. I use it in combination of float with 3 in tablets.
    1. 4 years ago
      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.

      Liquid Chlorine No More
      I have been using Liquid Chlorine from In The Swim for several years. The 5 gallon liquid chlorine started feeling heavier and heavier. This is a great (and lighter) replacement. Works just as well.
    3. 6 years ago
      Won't switch back!
      I ALWAYS use liquid chlorine and would pick it up with my groceries while at my local Wal-Mart. The huge bottles took up most of my cart not to mention mixing with groceries never set right with me. I saw this product online and with the free shipping thought, why not. When I first received the package, I thought something was wrong because the box was so small. The bottles were really little which really worried me. I can't believe how well they work. One of these little bottles works better ... read more and lasts longer then a whole gallon jug of the other stuff I used to buy. It dissolves quickly and does not leave a powder residue on the bottom of the pool floor. A little more expensive then what I was paying before but I use less and it gets delivered right to my door. So worth it!

    In The Swim Knowledge Pool: Pool Shock

    In The Swim's Dr. Pool

    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.
