      super shock
      Was having trouble maintaining a chlorine level due to locked up chlorine. After adding 2 bags of super shock,I immediately saw improvement.

      Used on new pool
      I had a brand new pool that had been filled for five days, and didn't have any circulation or filtration. Things were starting to get cloudy and a little green (quick). Once I had the filtration system online, I dosed the water according to instructions, and the water cleared up quick.

      We openned our pool this year without knowing our cover had small holes in it. Needless to say, first time we had openned the pool with problems. I ordered this product and 2 applications brought the wster back to crystal clear!

      I have ordered from in the Swim for years now and I always get exactly what I order and it arrives the next day most of the time. All of their products work great and are fresh, never clumpy.

      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.

      HTH Shock
      Great shock - you can use in the morning before swimmers arrive and it will dissolve and is ready to go before lunch. Great product and great service from In The Swim as always.

      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.

      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!

      Great Product
      I was told by a local pool salesman that lithium based powder shock was better than the liquid non lithium based shock I was using but my problem was no one sells it around me SO In the Swim to the rescue once again! I found it here, got the delivery quickly and used the proper amount to shock my pool and overnight my pool was crystal clear!! Thank you IN THE SWIM!

      get more years out of your liner...
      lithium based shocks are the CLEANEST and PUREST forms of chlorine available for pools. When u use lithium shock u dont get that white cloud that u get with calcium shock and u dont have to worry about bleaching your liner.... ever!! just sprinkle it around the deep end with the filter running and your done..... its a little more money... but have u priced a new liner??? :)

      We left our pool off for a week accidentally and here in the south that means algae!! We cleared most of it out, but it still needed super chlorination! This product worked perfectly!! We had sparkling pool water in 2 days! Thank you for making quality products at affordable prices!!! Would buy again and recommend!!

      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.

      Super Pool Shock
      I was having trouble getting my pool open this year and couldn't knock out the algae for some reason. I ordered the Super Pool Shock from In The Swim, treated it twice, and the algae cleared up!
