      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.

      Cann't say enough good things about this product. We had to drain out 56,000 gallon pool twice in 2 months because of chemicals bought at a discount store. After talking with the great staff at INTHESWIM we ordered this and put it in every week as instucted and our 6 grandchildren haven't missed a day of swimming. It's everything it says it is and along with the clorine tablets our pool has maintain balance for the first time all summer. Finally we can just enjoy!!!!!! Thank you INTHESWIM

      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!!

      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.

      works as expected
      I have a 30000 gallon pool that was nasty green with turtles and frogs living in it. I put 8 bags in the first time and in 2 days most of the green was gone. Checked the chlorine level and was 0. Put 5 more bags in and the green went away. Now just cloudy and needs vacuuming. This works as it should I will buy more.

      It Works
      After years of variable results trying to control algae with my epoxy in-ground pool I've settled on (1) maintaining an inexpensive copper-based algicide, and (2) shocking with this product whenever I see green starting to come back. Epoxy doesn't tolerate long-term high chlorine concentration, but a short-term blast (2 x 1-lb packets in an 18,000 gal pool) doesn't seem to do much damage, and keeps the algae within reason..I don't use tabs or floaters anymore. Just sprinkle shock granules evenly ... read more around the surface and stir them in with my net.

      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.

      Good Product
      I only use chlorine free shock because I use a copper ionization water purification system for my pool. No chlorine, no salt and no smell. JUST PURE H2o. I have bought pool supplies from IN THE SWIM for 12to15 years. I have had no problems what so ever. Thank you, ITS, Hillbilly Paul

      Satified customer for 20 years !!
      We have been very satified IN THE SWIM customers for 20 years, yes 20 years. We buy all our pool chemicals through your company. The Lithium Pool Shock is ESPECIALLY AWESOME as it dissolves very quickly, does not leave any residue and is vinyl liner friendly. I have & will continue to recommend all IN THE SWIM PRODUCTS to any & all that ask just where we shop for our pool chemicals as IN THE SWIM products keep our pool sparkling clear.

      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.
