      Great product
      I am an In The Swim Customer. First year to use this product and am so pleased! Wish I had known before. No more Ph up and down. Chlorine tabs last longer. Water balance maintainence is so easy now! When I test my water it is always on the money. Highly recommend.

      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.

      Best Purchase Ever
      I started using this product two seasons ago. We were having an awful problem with algae and cloudiness. We have a 17x35 foot inground pool. I can't begin to tell you how much we spent on algaecides and other products just to get our water clear. I found this product and ordered it. I will never stop using it. This past summer we did not have any problems what so ever with our pool water. Was sparkling clear all summer and when we had opened it up in the spring we had no algae to worry about. We ... read more also noticed that we don't use as much chlorine as we have in the past years. Love this product just wish it wasn't so costly. Hope they keep manufacturing it. Makes our lives so much easier for our pool maintenance and keeps the water sparkling clear. Thumbs up! I would recommend this product for everyone.

      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!

      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.

      Just what I needed!
      I purchased the chlorine neutralizer from In the Swim because they offered the size I needed. The price was excellent and they shipped it quickly; we received it just 2-3 days after ordering. I will purchase this from In the Swim again.

      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.

      Alkalinity Increase in AR
      Wow! I have bought a lot of different products and have never had the Alkalinity level up to where it needs to be in the last few years. Every time it rains my balance fails plus we loose about 1/2 inch of water per day due to the heat and humidity levels. I bought the bucked, poored half in the pool, the next day poured the remainder in the pool. My PH is perfect!!!!

      Great sodium bicarbonate
      I am a CPO. My pool had very low alkalinity that couldn't even be tested. I used this product and now my pool is at a steady 100ppm. Plus can't forget to mention great price and low to no shipping fees

      Easy to use
      I was advised several years ago to place the dry acid in a stocking (I split 8 lbs 4 ways) and hang into the pool very early after opening. Takes about two weeks for the solid to dissolve but the results are great.

      Disolving product
      Cyanuric acid is a white powder or granular product which is usually added to the pool water through the skimmer. Backwash the pool filter first, then remove the pump basket and restart the system on "filter" and add Cyanuric acid slowly to the skimmer closest to the pump. Stabilizer dissolves very slowly so we add it to the skimmer to allow the product to reach the pool filter where it can dissolve slowly over time. Do not backwash the pool filter for a few days after adding stabilizer. It ... read more needs this time to dissolve. Cyanuric acid has a low pH. Adjust the pH level of the pool water to 7.5 - 7.8 once the stabilizer has fully dissolved or after a couple of days.

      great value to buy on line. thet have everything I need for my salt water pool..

      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
      This is so easy to use. So much safer than using liquid.

      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!

      Worked Great!
      Here in Memphis, TN we have naturally very soft water (20ppm) out of the tap. I was noticing the mortar from the stone copping in the bottom of the pool. I used the product in my endless pool to bring it up to 200ppm. The mortar has stopped eroding away. I will continue to use this as needed.

      Worked. Easy to use
      Normally the water we put in the pool is very hard, but due to very heavy rains over several weeks, the calcium hardness in our pool was very low. Added this product over several days to increase by 50ppm each time. Worked great!

      Pool chemicals
      Got what I ordered in a timely manner. Would be a 5 if they included some kind of measuring device.

    In The Swim Knowledge Pool: Water Balancers

    In The Swim's Dr. Pool

    Why Pool Water Balancers are Important

    Pool water balancers help you manage water quality and avoid pool staining from improper water chemistry. In addition, pool chlorine levels are regulated by pool water balance levels, and incorrect ranges cause skin and eye irritation, and destroys chlorine's ability to kill bacteria and other harmful contaminants.


    •    - High pH and alkalinity levels also makes chlorine very sluggish and at a pH of 8.0 over 50% of your chlorine is wasted.
    •    - Low pH is also a problem, and at a pH of 7.0, chlorine is overly active and depletes more rapidly.
    •    - High pH and alkalinity levels can cause unsightly scale deposits, cloudy water and eye irritation.
    •    - Low pH and alkalinity levels can cause etching and corrosion to pool equipment, covers and pool surfaces. 
    •    - Low alkalinity levels makes your pH level erratic and unstable, even after adjustment.
    •    - High alkalinity levels makes your pH level overly stable and difficult to adjust pH up or down.
    •    - Low calcium hardness creates aggressive water that seeks to satisfy a demand for hardness, in troublesome ways. 
    •    - Low stabilizer levels allows the sun to burn-off chlorine as fast as you can add it, resulting in unsanitary pool water.

    In order to maintain swimmer comfort and health and to protect the condition of pool surfaces and equipment, it is important to keep both pool ph chemicals on-hand. Other water balance levels are slower to change, but be sure to test and adjust alkalinity, hardness and stabilizer levels every spring, and each month during the season. With regular pool water testing, it's easy for any pool owner to make chemical adjustments and maintain balanced pool water. 

    •    - pH Increaser is a base used to raise low pH levels when 7.2 or lower
    •    - pH Reducer is an acid used to lower pH levels when 7.8 or higher (also lowers Total Alkalinity)
    •    - Alkalinity Increaser is used to raise low alkalinity levels when below 80 ppm
    •    - Calcium Hardness Increaser is used to raise low hardness levels when below 200 ppm
    •    - Stabilizer or Conditioner (Cyanuric Acid) is used to protect chlorine from the sun, best in range of 20-50 ppm

    As with all of our products at In The Swim, our water balance chemicals are of first-class quality and are available at economical, affordable prices. With the help of a good test kit and quality pool balancers, pool owners can easily maintain high water quality to protect their pool surfaces, reduce chlorine expense, and protect the health of swimmers. Water is balanced when pH, alkalinity, calcium hardness, chlorine and stabilizer levels are all within their recommended ranges: 

    •    - pH: 7.2 to 7.8
    •    - Total Alkalinity: 80 ppm to 120 ppm
    •    - Calcium Hardness: 200 ppm to 400 ppm
    •    - Stabilizer (Cyanuric Acid): 20-50 ppm
    •    - Free Chlorine: 1.0-2.0 ppm
