      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

      Convenient but pricey
      I needed to add some stabilizer to my AG pool to hold the chlorine levels after a rainy May had depleted the CYA. However, dry CYA takes a week or more to dissolve, and usually you have to buy many pounds of the stuff. I only needed a little. I thought I would give the liquid a try. The bottle I got was not as "gluey" as other reviewers have said. I shook it really, really good, poured a very fine stream in front of my return. Some still collected on the bottom, but a little brushing stirred it ... read more up and it dissolved. It took about a day for it to fully circulate in my pool and for my test levels to be dependable, but I did get my small controlled increase that I wanted. I wish the price was better though- convenience costs. I also had to add some dry acid to bring the pH down. The bottle says it has a "salt friendly" pH- which apparently is higher than the 7.5 neutral pH that I prefer.

      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.

      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.

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

      Better than Muriatic
      A little pricier method of reducing ph than muriatic acid, but much better odor (almost none), and a better symbiotic chemistry for salt water pools. Water so clear it looks like liquid air. If you don't like the smell of liquid acids, you will love this method.

      greatest product i've used
      i just drop one tablet in every week to keep my pool sparkling clear and its so easy to use, i've even given a few tabs out to friends for their pools because it was so good. recommend to all who have an aboce ground pool. less maintenance on pool and survives our rains and heat without touching the balance of the water..... pleasantly pleased

      Easy but ...
      I'm into the second bucket and have just rationalized that this product was interacting with my weekly Super Shock and causing cloudy water. I quit adding the Super Shock two weeks ago, rely solely on the chlorine tablets in the floater to sanitize and now my water sparkles. My weekly pool maintenance is now down to 3 products (Chlorine Tablets, phree & clear tablets, and 4 oz of Algeacide 60). I have a 16 x 32 vinyl-lined pool with a 9 ft diving end (25,000 gal) and live in Central Florida so ... read more water balance can be a challenge. I am now "phree" to enjoy the water!

      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 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

      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

      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!!

      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.

      Really does work!
      We tried this last year for the first time because we seemed to be going through 2 bags of shock (how we chlorinate the pool) every other day. Mixing it in a bucket never seemed to work. As other people have said, it won't dissolve and it just winds up on the bottom of the pool. This year we gave it another try. This time slowly putting it through the filter. What a difference! Now I'm adding 2 bags of shock every week and a half. We added this about a month ago and it's still working ... read more great. Water is sparkling clear. Love this stuff!

      Satisfied with product, price and shipping ! Will definitely buy again.

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

      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 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.

    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
