1. Introducción
BAYROL pH Minus Granules are specifically formulated to quickly and effectively lower high pH levels in swimming pool water. Maintaining an optimal pH balance (typically between 7.0 and 7.4) is critical for the efficiency of pool disinfectants, such as chlorine, and for ensuring a comfortable and safe swimming environment. This product is a fast-dissolving acid granule of high chemical purity, designed to prevent additional corrosion that might occur with other pH-reducing agents like hydrochloric acid.

4. Instrucciones de funcionamiento
4.1. Dosis
To lower the pH value by 0.1, 100 g of pH-Minus are required per 10 m³ of pool water.
- Determine the required amount of pH Minus Granules based on your pool volume and the desired pH reduction.
- Using the included measuring spoon, accurately measure the required quantity of granules.
- Distribute the measured dosage evenly into the pool water at several points while the circulation pump is running.
- Allow the pool water to circulate for at least 2-4 hours after adding the product.
- Re-test the pH level after circulation to ensure the desired level has been reached. If necessary, repeat the dosage process in smaller increments until the optimal pH is achieved.

5. Mantenimiento
Regular monitoring of your pool's pH level is essential for effective water treatment and swimmer comfort. It is recommended to check the pH level at least once a week, or more frequently during periods of heavy use or after significant rainfall.
- Store the product in a tightly sealed container in a cool, dry, and well-ventilated area.
- Keep the measuring spoon clean and dry after each use.
- Ensure the product does not come into contact with other chemicals, especially strong acids or bases, unless specifically instructed.
6. Solución de problemas
6.1. pH Level Not Decreasing
- Insufficient Dosage: Ensure you are using the correct amount of pH Minus Granules based on your pool volume and the current pH level. Re-calculate and add more if necessary.
- Poor Circulation: Verify that your pool's circulation pump is running effectively and that the product is being distributed evenly throughout the water.
- Water Alkalinity: High total alkalinity (TA) can buffer pH changes. If pH is difficult to adjust, check your pool's TA level.
6.2. Granules Not Dissolving
- Insufficient Water Movement: Ensure the circulation pump is running.
- Aglutinación: If granules clump, gently break them apart or pre-dissolve them in a bucket of pool water before adding to the main pool.
