      HTH shock and swim
      All i have to do is sprinkle the powder around the pool and it does the rest.I am not good at balancing the chemicals.And since i started using shock and swim,it makes life alot easier.We don't have to worry about getting in the pool too soon after treatment. Its great! And the water is crystal clear!

      Keeps water clear especially with varying weather
      I use HTH Shock-N-Swim especially during those "short rain - hot sun - might rain again days". I can add the Shock-N-Swim to pool with the first rain. If the day clears up I can swim right away without worrying about the time. Also great if someone decides to swim or use the hot tub after I just used shock. No waiting, no worrying.

      My first source for everything for my pool
      I have a somewhat unique situation. I made my own mini-pool and waterfall. The challanges of keeping it safe and clean change often, but I can rely on In-The-Swim to solve my problems, and have the needed supplies here quickly and at a great price. I feel confident in In-The-Swim as my resource for all my needs.

      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.

      Great Products & Reasonable Price
      I have used In the Swim for many years. I have purchased solar covers, winter covers, filter assemblies, and most all of my chemicals. These folks have always operated in a first class manner. I had one issue with an order, but customer service went above and beyon to correct the problem. A pleasure to do business with them.

      Excellent Product!!
      I love this product and used in conjunction with my Perma Salt System and the opening and closing kits from In The Swim, my pool is AWESOME!!!!! I just opened my pool today and it is CRYSTAL CLEAR!!!! My pool company actually saved me money on the mineral ionization system by using this shock weekly and only monitoring pH, Calcium, Alk and copper levels. This is worth it!!! Thanks In The Swim for awesome products!!!!!! Great sales too allowed me to stock up!!!!

      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.

      Excellent Compliment for Chlorine Users
      I learned this from several pool chemistry experts, plus through use over years. If you use chlorine to general purpose sanitize your pool, this is an excellent complimentary shock treatment. It disperses well and you will not have any where near as long of a wait time as super-shocking with chlorine to keep the kids/guests out of the pool. Individual packets are a plus, but it is more costly than chlorine. It's worth it as an alternative shock.

      Best shock ever
      I started using this shock a couple of years ago due to it being the highest chlorine content I can find any where. Price is very good, and as usual u get what u pay for. This is money well spent.

      Like this much better than regular shock!
      I like the super pool shock much better than the regular pool shock. The super pool shock dissolves much more quickly and does not require mixing prior to adding to the pool. Also, since a bag of this treats 15k gallons vs. 10k gallons for regular pool shock, I can treat my 30k gallon pool with 2 bags of super pool shock instead of 3 of regular shock. Keep that in mind when you are pricing them out.

      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.

      Excellent product
      I have use this Lithium pool shock since I purchased the pool 8 years ago. I use it as shock and daily clorination. My liner still looks great. I know others who had the pools for less time and bleached their liners with cheaper product.This product disolves very quickly clears any cloudy water fast. Once again shipping fast & free.

      Thanks for Reviews.
      Had pool over 15 years. Liner. In ground. Used standard shock. I read reviews and all said "Worth the extra money" could not have said it better. I will not go back. Total positive noticeable difference from first bag.

      As a "Super Shock" user for 9 years, I must admit I had no idea anything could be better...but this is it. I hesitated on the price at first but gave it a whirl based on other reviews.It will end up costing much less because I use half compared to the shock. In the nine years I've own the pool I have never seen water so clear..mirror finish! I'm hooked! Algae after rain on a hot day was normal...no more...perfect!
