      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!

      Great dissolving product
      This is my first year of using In the Swim products. I found it difficult to find my local pool store open at a time convenient for ME. I was dissatisfied with the products from my local mass discount store even though their hours suited me perfectly. Ah, the great solution-an internet pool store. I have been pleased with the way the products, especially the shock works in our pool. I like the way it dissolves. (Not all shocks do this!) And who can beat the convenience? Order one day and receive ... read more my order usually the next day, right at my door. No lugging everything home. Thanks In the Swim!

      Bought to help in the management of our salt system pool after having the same recommended by the pool supply where a water sample was taken which is about 29 miles one way.

      Great Product
      I purchased this product after reading all of the other reviews. I'm glad I made the decision to purchase the Lithium Pool Shock. This is the first year my husband and I have owned a pool and we've spent a great deal of money on chemicals to clear up our cloudy pool. This product cleared up our pool within 2 hours. You will spend less money overall if you start out with this product first. No cloudy residue; dissolves quickly; fast acting;

      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!!!!

      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??? :)

      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.

      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!

      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....

      I use this product when I have suprise visits from my children and grandchildren, and I want to give a quick shock treatment. 15 minutes later the pool is good to go. Also no eye burning for the young grandchildren.

      Good Value, Works Well
      I have been using the chlorine free shock in my in-ground pool for years. Works well with Chlorine chemistry control and is good value for price.
