      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??? :)

      Keeps me from hiring poolman
      I am a 57 year olf female and I got tired of the 2 1/2 gallon chlorine shock bottles from the pool store. This is a great source of unstablized chlorine. I use 2 bags to shock my 18 x 36 liner pool once per week and when my stablizer reading starts getting high from the 3 inch stablized chlorine tablets I put in my feeder then I use this as a source of unstablized chlorine and cut back on the tablets. The cost is a little high but the altermate is dumping a lot of water from the pool to reduce ... read more stailizer level. I never close my pool.

      Best Product We Ever Used!!!!!
      We have an in-ground pool and been having problems with under our liner algae, we put in the lithium shock ran the pool filter over night and the next day it was all gone, let me also add we have been fighting this since we opened it in the spring, I wish we would have used this sooner!!! GREAT PRODUCT!!!!

      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.

      Simply the best and most convenient to use!
      I order about 3 cases of this every season and it is so easy to use. No measuring; 1 1lb. package for every 10,000 gallons of water. I have used other brands from the local pool store and did not have the same results as I get with this shock. Will never ever run out of it again! Order on the phone or over the net and I have the next day or day after and they even deliver on SATURDAYS! Oh and by the way.......customer service....simply the best when I have questions over the phone! 5 GOLD STARS for them!

      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!!

      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.

      Chlorine Free Pool Shock
      I have ordered Chlorine Free Pool Shock a view times now and they are working like a charm and are much, much cheaper than purchasing them at the local store. My water stays crystal clear, even if I don't add 2 bags every week ( Have a very large above ground pool). It seems like before you can even hit your send button on the computer the items arrive. I have already recommended In The Swim to my friends with pools. Not only this product is excellent but others I had ordered in the past. Great ... read more company to deal with.

      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!!

      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.

      Unbelievable Quick Results
      For whatever reason, my water had taken on various problems. As I followed a number of suggestions, nothing was working. I ordered and used, for the first time,Assure MultiShock. Within reasonable time, my water was clear and had a much smoother feel to the skin.

      Best shock I've used in 27 years!
      I tried Assure for the first time a few weeks ago and was very impressed by how fast it works to raise the chlorine level in the pool. Also, the effects of the shock treatment last longer than products I've used in the past. While it is at the high range of pricing for shock treatments, it requires less product to achieve these results.

      Great Product
      Have always been happy with these products and how quickly I receive them after I order. Love to read the reviews and it has helped me more than the local pool stores. Ordered a salt generator from here and it saved me hundreds of dollars.

      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.

      the only shock i'll ever buy
      pool was green for weeks. kept dumping shock from wal mart and other local stores in and might as well have been throwing my money in the pool because if anything it was just getting greener. relative told me about in the swim super shock and in 2 days we were swimming in a clear pool, i was amazed! It was delivered amazingly fast too. i am a skeptic by nature and was skeptical about this too, but now i will never buy another shock. i have referred several friends who feel the same way too. ... read more amazed there are 2 bad reviews on this stuff.

      Great Shock
      I live in Oklahoma. Our summers are VERY hot. I use Pristine Blue products in my pool which I wish you carried at In The Swim. However, the non-chlorine shock that is recommended for use with Pristine Blue doesn't work well enough in the 100 degree heat. So I use this great shock weekly along with my Pristine Blue products. I have been doing this for the past 3 summers and my pool water is always BEAUTIFUL!! I also used this shock during the opening of my pool and I couldn't believe how fast the ... read more water went from green-black to blue! I also love the convenience of overnight delivery.
