In The Swim's pH Reducer will help lower the Total Alkalinity and pH levels in your pool spa and hot tub for a safer and cleaner swimming experience. With an active ingredient of sodium bisulfate, or commonly known as dry acid, In the Swim pH Reducer comes in a granular state to ease the flow of measuring and addition into your pool or spa. Using a pH Reducer will protect chlorine effectiveness and balance the overall chemistry of the swimming pool.

Protecting Your pH Level

The pH level of your pool water is a vital element of your pool's overall water chemistry. pH measures how acidic or basic the water is on a scale of zero to 14, with the ideal pH for swimming pools falling in the range of 7.2 to 7.6. In the event your pH levels get too high, the sanitizer in your pool, spa, and hot tub become around 50% less effective. In addition to having a higher pH level, algae blooms can start to appear due to the sanitizer being less effective in the water. High pH also promotes scaling, calcium in the water starts to precipitate, and your pool or spa water will become cloudy.

To prevent reaching a higher pH level and these problems from occurring, it's important to test your water to keep an eye on the pH of your pool or spa. Whenever pH rises above 7.6 - 7.8, Use In the Swim pH Reducer to drop the pH level back into the 7.4 - 7.6 range. Once pH is back in the ideal range, your chlorine sanitizer will be more stable and able to work more effectively at killing bacteria and controlling algae. Other water balance parameters will become more stable as well.

Decreasing Total Alkalinity

Total alkalinity is measured by all the hydroxides, carbonates and bicarbonates floating around in your pool water. It is recommended to keep Total Alkalinity between the 80-120 parts per million (ppm) range for concrete or gunite swimming pools, and 125-150 ppm for vinyl, fiberglass and painted pool surfaces. Alkalinity should be tested on a weekly basis as well as after every addition of a pH or alkalinity increaser or decreaser.

Common Questions:

What does pH Reducer affect?

In The Swim pH Reducer lowers your pH and Total Alkalinity levels in your water.

How much pH Reducer should I add to my pool or spa?

Pool Dosage: Do NOT add more than 20 oz. of pH Reducer per 10,000 gallons of water at one time.

  • 7.6 - 7.8: Add 15 oz. (about 2 cups) per 10,000 gallons of water
  • 7.8 - 8.0: Add 20 oz. (2-1/2 cups) per 10,000 gallons of water

Spa Dosage: Add no more than one ounce of pH Reducer per 500 gallons of spa water at a time. The one ounce should be added to a bucket of water and pre-dissolved before adding it to the spa.
