    Pool Shock

    1. 2 months ago
      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.

      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!!

      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.

      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!!!!

      Does the job
      I bought the hth Super-In-Swim to try it and I very pleased with it. It does a better job than what I had been using for several years. The cost is a little more but it is worth it. Here in Georgia, it does get very hot and humid so the chlorine does not remain in the water very long, however this stuff holds up a little longer.

      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!
