In The Swim pH Increaser Overview
The In The Swim pH Increaser is a fundamental product for anyone serious about maintaining a healthy and enjoyable swimming pool. Pool chemistry is a delicate balance, and pH is arguably the most critical parameter to monitor. An ideal pH range of 7.4 to 7.6 is essential for several reasons, impacting everything from swimmer comfort to the longevity of your pool equipment.
When pool water pH drops below this ideal range, it becomes acidic. This acidity can lead to a host of problems, including eye and skin irritation for swimmers, corrosion of metal pool components like ladders and heaters, and degradation of pool liners and surfaces. More importantly, low pH significantly reduces the effectiveness of chlorine sanitizers, meaning you’ll need more chlorine to achieve the same sanitizing power.
This product, formulated as 100% granular sodium carbonate (also known as soda ash), provides a straightforward and highly effective way to counteract low pH. Sodium carbonate is a strong base that, when dissolved in water, releases carbonate ions which neutralize excess hydrogen ions, thereby raising the pH. Its granular form makes it easy to handle and distribute, though care must be taken during application to prevent temporary clouding.
The 45-pound bulk packaging of the In The Swim pH Increaser makes it an economical choice for both residential pool owners and those managing larger commercial pools.

Proper pH balance also extends the life of your pool filters and pumps by preventing mineral scaling and corrosion. It creates an environment where other pool chemicals, such as alkalinity increasers and calcium hardness increasers, can work more effectively. Without a balanced pH, your entire pool chemistry can be thrown out of whack, leading to a frustrating cycle of chemical adjustments.
Many factors can cause pH levels to drop, including heavy rain, swimmer load, and the use of certain sanitizers like trichlor tablets, which are acidic. Having a reliable pH increaser like this one is therefore a necessity for proactive pool maintenance. Regular testing and timely adjustments with a quality product ensure your pool remains a safe, clean, and pleasant place to swim.

FAQ about In The Swim pH Increaser
Understanding the common questions surrounding pH balance and the use of the In The Swim pH Increaser can help pool owners achieve better water quality and peace of mind. Here are some frequently asked questions with detailed answers.
1. What is pH and why is it important for pools?
pH is a measure of how acidic or basic your pool water is, on a scale of 0 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic (alkaline). For swimming pools, an ideal pH range is 7.4 to 7.6. This specific range is critical because it ensures swimmer comfort, optimizes the effectiveness of chlorine sanitizers, and protects pool equipment and surfaces from damage.
When pH is too low (acidic), it can cause eye and skin irritation, corrode metal components, and rapidly deplete chlorine. When pH is too high (basic), chlorine becomes less effective, leading to cloudy water, scale formation on surfaces and equipment, and reduced water clarity. Maintaining the correct pH is the foundation of good pool chemistry.
2. How do I use In The Swim pH Increaser?
First, always test your pool water’s pH level using a reliable test kit or strips. Once you confirm a low pH, determine the required dosage based on your pool volume and current pH reading. The packaging for the In The Swim pH Increaser typically provides a dosing chart.
It’s generally recommended to add the granular product slowly, either by broadcasting it evenly over the deep end of the pool or by pre-dissolving it in a bucket of pool water before slowly pouring the solution into the pool. Always run your pump for several hours after adding chemicals to ensure proper circulation and mixing. Retest your pH after 4-6 hours, and avoid swimming for at least 30 minutes to an hour after application.
3. How much In The Swim pH Increaser should I add?
The exact amount depends on your pool’s volume and how far below the ideal range your pH currently is. A common guideline for a 10,000-gallon pool might be to add about 1 pound of pH increaser to raise the pH by 0.2 units. However, always refer to the specific instructions and dosing chart provided on the product label. It’s better to add smaller amounts incrementally and retest, rather than adding too much at once, which can lead to overshooting the target pH or causing temporary cloudiness.
4. What is soda ash and is it safe for pools?
Soda ash is the common name for sodium carbonate (Na2CO3), which is the active ingredient in the In The Swim pH Increaser. It is a naturally occurring mineral and a very common, effective, and safe chemical for raising pH in swimming pools when used according to directions. It’s widely recognized and approved for pool use.
Sodium carbonate is a strong base that works by reacting with the acidic components in the water, thereby increasing the pH. It is a stable compound and, when handled properly, poses no significant risk to swimmers or pool equipment. For more scientific information on sodium carbonate, you can consult Wikipedia’s entry on Sodium Carbonate.
5. Can I add too much pH increaser? What happens then?
Yes, it is possible to add too much pH increaser. If you add an excessive amount, your pool’s pH can become too high (alkaline). This can lead to several problems, including reduced chlorine effectiveness, cloudy water, scale formation on pool surfaces and equipment (like heaters and salt cells), and even skin and eye irritation. High pH also often causes total alkalinity to rise, which can make it difficult to adjust pH in the future.
If your pH becomes too high, you will need to add a pH reducer, typically muriatic acid or sodium bisulfate, to bring it back down. This highlights the importance of testing regularly and adding chemicals in small, measured doses.
6. How long does it take for pH to adjust after adding the product?
After adding the In The Swim pH Increaser, it generally takes a few hours for the chemical to fully dissolve and disperse throughout the pool water. It is recommended to run your pool pump for at least 4-6 hours to ensure thorough circulation. You should retest your pH after this period to determine if further adjustments are needed. Avoid retesting too soon, as you might get an inaccurate reading due to uneven distribution.
7. What are the signs of low pool pH?
Several indicators can signal low pool pH. Swimmers might complain of burning eyes, itchy skin, or dry hair after swimming. Visually, you might notice corrosion on metal components like ladders, handrails, or heater elements, which can appear pitted or stained. The water might also appear dull or less inviting, and chlorine may seem to dissipate very quickly, requiring more frequent additions to maintain sanitizer levels.
8. How does low pH affect pool equipment and swimmers?
For pool equipment, low pH, being acidic, is highly corrosive. It can lead to the deterioration of metal parts, including pump seals, heater elements, and even the rebar within concrete pools. This corrosion can result in costly repairs and premature equipment failure. It can also etch plaster surfaces and cause vinyl liners to wrinkle or become brittle.
For swimmers, low pH water can be very irritating. It strips the natural oils from skin and hair, leading to dryness and discomfort. More severely, it can cause red, burning eyes that feel similar to chlorine irritation, even if chlorine levels are normal. Maintaining proper pH is therefore crucial for both the health of your pool and the comfort of its users.
