    Pool Shock

    1. 7 years ago
      Great shock
      This is the 4th summer that we've had our in ground pool. We have a local pool supply store right here locally. I've used their supplies as well as the local Wal-Mart. This is the first summer that I've strictly used In the Swim and also the first summer that my pool has been crystal clear. Every other year I have battled my pool turning green, but not this year. I will continue to use In the Swim. Their products are AWESOME and you can't beat the price.

      Great product
      After searching the internet for the best prices on different pool chemicals I found in the swim. Their prices are always cheaper than other companies selling the same product. I haven't purchased anything from them that hasn't turned out to be a great product! I also know that I can order the product and it will be at my door the next day. So if I am having a problem with my pool its just as convient to order from you guys as it is to visit my local pool store. Thanks!!

      very good product
      I had a new liner put in a couple years ago. My last liner bleached out to almost white... shocking with chlorine. My pool is only 16,000 gallons and I use 3 inch chlorine tablets using a inline chlorine canister. I use 1 1/2 packages this product every week and a half for shocking. I do this for 3 or 4 cycles till combined chlorine goes up, then I use liquid chlorine to break that. I try to keep chlorine levels 6-10 PPM when I do this, so it does not bleach liner. I am old school with ... read more chemicals. I have switched from in the swim 3 inch tablets to SAMS because they do not have cyanic acid stabilizer in it. I think I pay a little more for this. They say to keep this level lower now, than the old standards used to be....

      Best Non Chlorine Shock!
      I have been using this shock since I got my AG pool for 3 years strong. I use the mineral or power ionization to keep my pool clean. It has never failed me! People remark how clean my pool is! In The Swim is FAB! Fast shipping! Their openining and closing kits are SUPERB too! My pool is crystal clear EVERY spring! I am in it within a week once it warms up with the solar cover I also got oh and the filter system too as the one failed from the pool company after the start of my second season! In ... read more The Swim...YOU ROCK! Thanks!!

      A Great Product
      I have been using this product as a supplemental pool shock for 16 years. I have lots of grand kids and like to keep my chlorine level at 3ppm. After heavy swim usage I shock with chlorine-free shock to sanitize with out raising the chlorine level. As a retired Pool Store employee I have recommended this type of shock many times to customers who have had high chlorine levels but needed additional water sanitation.

      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.

      Amazing!
      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've never had to balance the water in our pool or open it in the spring. My husband always did that. Then he died unexpectedly and I had to do the pool. I didn't have a clue what to do or how to do it and no one to ask. The first two years it took me a month to balance the water and allot of reading and allot of chemicals. Then I read about Lithium Shock. I cleaned all the debris out, added the Lithium, waited four days, added some regular shock, waited a couple of days, added an ... read more algaecide, then shocked again. After that I used the chorine tablets in the skimmer and it's clean!! I vacuumed every day but this has been the least money I've spent on chemicals and fastest, easiest balancing I've ever done. The only problem was the ph was really high so I added ph reducer and borax and that seemed to solve the problem. I love this product!! I only used half of the order of Lithium shock ($25 worth) and six bags of regular chorine shock so I'm way ahead of the game money wise.

      Shocking Results!
      This is the best pool shock I've found! Just follow the directions and your pool will sparkle all summer long. I love the ease of ordering and the fast to my door delivery. I generally order enough for the summer as the box(es) fit well on the shelf in my poolhouse for easy access. The only qualm I have is the lack of easy opening as the bags require the use of scissors or some other sharp tool to open them. But the 1 pound size is handy to use and easy to handle. I love In The Swim products and ... read more you know they are working when your neighbor says "Your pool always looks so clear and clean! How do you do it??" Thank You In The Swim for making my life easier and my pool look great!!

      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!

      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.

      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!

      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.
