      Chlorine Neutralizer did lower chlorine levels
      This stuff really works. Getting the right amount was a "guess" but did get it down - and fast.

      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.

      Wow- what an improvement
      Our well water is incredibly hard (more than 2000 ppm TDS). I tried several things and finally decided the failure to get a good readings was because the water was simply not absorbing the chemicals. I was a bit anxious but added the 2 gallons of stabilizer/conditioner and the pool has been sparkling ever since.

      Works when the other things are balanced
      Bought 2 gallons of this to bring up CYA from pretty much zero after winter cleanup. Pool is about 17000 gallons above ground. After adding first gallon nothing waited 24 hours still nothing added second gallon and got a slight reading. I ordered another gallon and while I was waiting went ahead and balanced the other things. PH was in range, but TA was very low. Well water so there's a lot of pool unfriendly content in the water. Threw a few boxes of baking soda in to raise the TA and suddenly ... read more the CYA numbers came up. Could have been nothing more than time, but seemed to me this doesn't work well if the TA is low. Once everything else got right the CYA number was there. If you're having problems with this try getting the other things balanced and hopefully you'll be as fortunate as I was.

      Awesome liquid conditioner
      I diluted it out, in other gallon bottles, and it completely dissolved nicely as I spread it by hand over the pool surface. I guess I will know how good it is, when I open the pool in the spring!!!! Much easier than the powder.

      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 !!!!

      Works great
      I bought this product a month ago because we where having problems getting the chemicals balanced which was causing our water to have a green tint. We applied a cap full in our pool in the evening and in the morning the pool was clear and the chemicals balanced. I would recommend this product to anyone.

      Can't Add Chlorine Forever Without Adding "PH Plus
      Continual adding chlorine lowers the PH of my pool. Gets real acidic after a while. PH Increaser adds alkalinity to get the PH back into an acceptable range. "PH Increaser" works well.

      Does the job.
      Does exactly what it was made to do, raise the CYA in the pool water. This is one of the only chemicals needed to be purchased from a pool store. Pros: Raises the CYA in pool water. Costs alot less than the liquid conditioner. Cons: Takes about 5 days of filtering pool to accurately test correct CYA level. If you add too much you will have to drain and add fresh water or use higher amounts of chlorine to achieve the same sanitary pool levels. Note: Stabilized chlorine tablets/pucks will also ... read more raise the waters CYA levels. Buy a good pool test kit and use it frequently.

      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.

      Very slow dissolve
      Have never used this product and didn't read all of the reviews. Don't know if the product dissolves faster in warmer water (late season), but it lay in the pool for several days before dispersing. Next year, may dissolve in a large bucket and then add to the pool.

      GREAT PRODUCT
      this is the first hardness increaser I've ever used that I didn't have to dissolve in a bucket first then add to the pool. you add this product right to the pool, no pre- dissolving. dosen't get any eaiser than this.

      Worked Great!
      My pool was green but not from typical algae, my chlorine level was high but not effective... turns out it was that my calcium hardness was low, and the pool store recommended 48 lbs.. i added the whole 45 lb bucket and my water was clear within about 6 hours!!!
    3. 1 decade ago
      Easiest Product To Use
      We have well water and when we had it tested there was NO metals in it whatsoever. We have some of the best drinking water ever, but it wasn't fit to swim in, so the first thing we had to do was add the calcium hardness to it. We bought this container from In The Swim and it was delivered right to our door. We added it to the pool which was quick and easy, since the directions were right on the container and it did the job perfectly! We've only had to add it that one time. Thanks In The Swim!! ... read more Now I buy all of our pool products from you!!

      Best Acid Ever
      Not that I can afford $100k for one gallon of acid, but at that price, this must be the greatest acid ever!
    3. 1 year ago
      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 product
      This is so easy to use. So much safer than using liquid.
    2. 6 years ago
      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!

      Awesome
      Worked like a dream no splashing like with liquid no mess

    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
