      Quick reasonable pool chemical
      Ordered Calcium hardness on Friday Afternoon and recieved on Saturday. About 2/3rds of the price of in store and I needed 75 pounds so good saving. I could not believe how fast I got this, will definitely look at In The Swim for future pool needs.

      Works Great
      Works as described and in the swim sends it to my door, I don't have to go to pool store and lug the stuff home. In the Swim has a chart that explains how much to add to your pool,

      Great product but way overpriced.
      The product does exactly what it was made to do. You can save a ton of money if you buy 50 lb. bags of Dow Flake or PURE calcium chloride (ice melt) at the big box stores for $22.00/50 lb bag.

      Did the job!
      Our pool had a ph of about 6.6 - 6.8 at the start of the season. We were able to bring all other water parameters into proper range, but needed to bring the ph up, and out if its acidic state. Used this product, as directed, and it got us dialed-in to 7.2 - 7.4 very quickly. Be sure to dilute in water before adding to pool (per directions). Get some!

      Easy to use
      being a pool owner for over 20 years and using in the swim products have made my pool wonderful year after year but remember the pH is the most important thing you can do after your pool is clean make sure your pH is at the proper level and buy all your products from in the swim

      Why the Extra Charge?
      In the Swim charges "handling fees" only observable when checking out. Low

      Great Chemicals
      Love In The Swims chemicals. That's all I ever use. Never had a problem. Pool water is sparkling clean. Always get compliments on it.

      Love It
      I have used this product for the last 3 pool seasons. It has made maintaining my pool so much easier. After I open my pool for the season I just add phree and clear tablets to a 1/1 ratio with my choline tablets. I have not had to add any other balancing agents. My pool is always perfect. It makes the water sparkle.

      Easy Pool Maintenance
      We installed our pool about 6 weeks ago. After our initial water fill, we had to increase the pH. Since then I have used 2 phree and clears in a floater every week and have had to do nothing else!! We also use the 3" chlorine tabs, weekly non-chlorine shock, and weekly algaecide 50 for maintenance. Our pool water looks awesome and it take so little time to care for the pool.

      Good Product
      I have bought the Phree and Clear tablets for the last two years. My review is like some of the others. The product works great at stabilizing the water. Holds chlorine in check, ph is good, etc... This year the product sent to me had about 6 good tablets. I complained to In the Swim "Swim Dr." and they sent me another bucket, but alas it wasn't any better. They refunded my money and I'm very satisfied with In the Swim, but really want the Phree and Clear tablets. I told them I couldn't be the ... read more only customer with this problem. They didn't respond to this statement? Possibly will try again?

      A Must Have!!!
      This product is a must have for all pool owners. When you happen to raise the chlorine level too high, this product will save day. It works and it works fast. Excellent product.

      IT WORKS!
      The pool chlorine was high for several weeks unable to swim. Used this and the following day the levels were down to where they needed to be for us to enjoy our pool ! THE KIDS WERE VERY HAPPY!

      How much does it contain?
      Since buying this product my hair and muscles have grown significantly. I am not sure what purity of weapons grade plutonium is in this product, but it definately cleaned up my pool, my neighbors pool, and the surrounding lakes are now all algae free for 50 miles!

      Great Price
      At just shy of 100 grand this muriatic acid did the job!

      So much safer
      Mom is the “pool boy” at our house so I love this stuff in comparison to liquid acid. No splash, no leaking, easy and light weight, small bottles that take up a quarter of the space. Wins all around

      Love this stuff, works like a charm :). It's so nice to not have to handle the liquid acid, especially when you are as clumsy as I am!

      Love it!
      I just ordered another 4 bottles of this powdered acid. I was skeptical when I ordered it for the first time and was very surprised at how well it worked. It's so much easier to use then the liquid and no harsh acid smell! It's even seems to work a little better than the liquid but that might be because you don't have to use as much. I am hooked and will be using this from now on. With my salt pool I am always fighting high PH & alkalinity and this seems to help keep it in control.

      Great Product
      Using Chemicals from "In the Swim" has made the maintainence on our 30 foot pool so easy that 15 min a day is all thats required to keep it clean and test the water balance. It has stayed stable all season with less cost than ever before. I'm very happy with their specials and the savings on S & H and utilize those to buy volume enough for us every time I can. Big savings overall. Keep up the great work !!!!

      alkalinity extremely important
      I purchase this on a yearly basis for my pool. The quality is very good. I check my pool every 3 or 4 days for chemical performance. Adding the recommended dosage as needed keeps my pool perfect and I use alot use less pH up and chlorine.

      Correct chemical balance
      When opening the pool this spring I had low alkalinity. Used this product to bring the pool water back into balance. Worked as advertised.
