      This product truly works
      I have a large concrete pool with a connecting spa. My spa and pool steps always turned a disgusting brown in the hottest parts of summer even if the chemicals were good. A kid at our local pool store sold me this (for $56!!!) and it worked instantly. I subsequently have bought it from In The Swim because of the more reasonable price. It does work best if you turn off your pool pump for a little while and let it settle. I usually get out my brush and brush it around, then turn the pump back on.

      Very Happy
      We had a inground fiberglass Pool install a month later had issues with staining. We search and heard about this product. We were very pleased with results. Pool looks way better.

      5 Year Old Liner Looks Brand New!
      Each summer start up, we have brown and yellow staining on the hard plastic surfaces such as the skimmer and steps and the liner has a dull brownish tint. We used Ascorb-X one year (which was a super product) but isn't as "environmentally safe" as Stain Free and is no longer sold. You must be sure the chlorine is low to apply this product or it will not work. If your water balance is good and chlorine low...the results are amazing. Don't be dissapointed if you don't see a change right away. Ours ... read more was significantly stained and after about 12-18 hours looked BRAND NEW! We added clarifier at the end of 24 hours and the pool is beautiful!!!!!

      Love this Stuff!
      I am still just a few years into owning an above ground pool. The first year was a disaster. The second was not a huge improvement. It was expensive, burdensome, frustrating and stressful. I was at the local pool store several times a week One day I ordered shock from In The Swim. I was hooked. It is August and my water has been sparkling clear all summer. All of my chemicals come from here. I get compliments on my clean water all the time. Best of all I enjoy the pool. I can finally say I am ... read more happy that I bought a home with a pool. I highly recommend their chemicals. As a bonus you will save tons of money.

      Great Pool Chemicals
      I have used In The Swim Pool Chemicals for about 10 years. I have used other chemicals when I would run out and need some right now, the other chemicals do not work as well as these do. I have had 2 friends buy pools and they use In The Swim Pool Chemicals also. I have another friend that converted to them and a nephew now that just ordered his first supply. I will never use anything else. Thank You In The Swim Rick

      This is amazing!
      We only heard about this product this summer, and I wish we would have found it sooner! I was a little skeptical when I ordered it, but that changed with our first use! I can't believe the extra "gunk" it removes with a backwash! The pressure on our filter dropped over 5 psi after use! Thanks In The Swim!

      It works!
      Despite my best efforts, I couldn't get my pool water clear. Finally determined dirty sand in the filter might be the culprit, so purchased this product. IT WORKED! I can delay changing the sand out, yay! About to purchase more to keep it on hand.

      Excellent Product!!
      I love this product and used in conjunction with my Perma Salt System and the opening and closing kits from In The Swim, my pool is AWESOME!!!!! I just opened my pool today and it is CRYSTAL CLEAR!!!! My pool company actually saved me money on the mineral ionization system by using this shock weekly and only monitoring pH, Calcium, Alk and copper levels. This is worth it!!! Thanks In The Swim for awesome products!!!!!! Great sales too allowed me to stock up!!!!

      Winter pill
      Used the winter pill last year had no algie when I opened the pool. If the winter pill works that good worth trying all the others.

      Love this value pack!
      I was very weary of using this over the winter instead of the other chemicals we usually winterize with in the past. Our pool water was fresh and clear when we removed the pool cover a month ago. We have used the spring pill for startup and one summer pull this far into the summer. Very pleased with these products and super easy to maintain the pool.

      Above ground start up kit
      Bought the kit to open up my pool. The kit was right but something has changed. It was always this this then this then this and finally this. Now it's follow the instructions on the bottle or package. When you read the directions on the product it doesn't talk about opening up the pool in the spring. I will buy from another supplier next time and see if they still have the opening instructions in the box. There is no guess work that way.

      wonderful chemicals!
      I have tried many other pool chemicals for our pool in the past and I wasn't satisfied with them because it seems nothing would clear up our pool water. Then when I found In The Swim I tried their products and boy was I surprised at the difference! I am grateful I can order from them and get my products the very next day! I will never try another pool supply store, In The Swim has a customer for life with me. Thank you In The Swim!

      Dependable chemicals
      Used in the swim pool supplies on and off the last five years. On the off years (2)I always had issues with chemical balance,and that was from a pool supply store. Last year I went back to ITS and the pool was perfect all season. Just put in the startup kit, kept up withchlorine tablets and had no problem. Just got done ordering my start up
