In The Swim’s pH Reducer 30 lb Bucket 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, our In the Swim’s pH Reducer comes in a granular state to ease the flow of measuring and addition into your pool. Using a pH Reducer will protect chlorine effectiveness and balance the overall chemistry of the 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, your sanitizers in your pool, spas, and hot tub become around 50% less effective, algae blooms start to appear, calcium starts to precipitate, and your water will become cloudy.

To prevent higher pH problems from occurring, keep an eye on the pH level of your pool and, whenever it raises above 7.6, Use In the Swims pH Reducer to drop the pH level back into the 7.4-7.6 range. Your chlorine will be more stable, and other water balance parameters will too.

Decreasing Total Alkalinity

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