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

      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!

      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.

      Convenient
      I always enjoy ordering products from In The Swim from my arm chair, and having them delivered to my front door. They are more reasonable in price than the local pool center.

      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.

      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.

      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 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 !!!!

      Chlorine Neutralizer did lower chlorine levels
      This stuff really works. Getting the right amount was a "guess" but did get it down - and fast.
    2. 3 years ago
      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.

      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.

      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.

      Have patience
      I have an in deck chlorinator that I used to drop 3" chlor tabs in for my source of chlorination before I retrofitted the system with a salt cell generator, therefore I had this in deck chlorinator not in use any longer until I realized it'd be perfect to pour the stabilizer granuals in and let them disolve slowly and ooz into the pool over a matter of days. I'm able to get a full 8lb pail in at a time. No fuss no muss. Works great.

      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.

      Great product
      This product dissolves instantly!! Works great too, in bringing down PH

      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.

      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?

      pHree & Clear Balance Tablets
      I really like to use Phree & Clear Balance Tablets in my pool all summer. Once I get my pool water balanced I use Phree & Clear balance tablets according to directions of one tab to each tab of chlorine and my water remains relitively balanced all by itself. I spend less time taking a water sample off to get it tested and more time enjoying my pool.

      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.

      Does what it's supposed to do
      Every summer the PH levels in my pool drop and it's important to keep it at the proper level. When using my test kit, if the PH is low I throw in a cup of this across the pool and it does the trick. Been using this product for many years.

      Can't do without it in Wisconsin
      I can't open my pool without this. When you have a big pool you need lots of the ph up . There isn't enough baking soda in the world to balance it seems. And as with all pool chemicals, please read the instructions.

      incresed the PH
      I tried everything to increase my pH this year and nothing would touch it until I bought this pH increaser. It is 100% soda ash. It took a few days and 20# but water is a perfect 7.5. It's just soda ash but if your water too acidic that is what you need. The container also has a helpful calculation formula on the bucket to figure gallons of water in pool

    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
