Sodium Bisulphate Powder.

Decreases the pH of water. pH, along with alkalinity, hardness and temperature are required to be balanced in order to prevent corrosion, scale formation or skin irritation.

Dosage: 10g per 1000 litres of water for a pH decrease of 0.2. Tip the required amount straight into the pool with the filter pump running. Results can be seen from testing after 8 hours (leave the filter pump running.

Additional info:

Sodium bisulfate is a dry acid that is commonly used in swimming pools to lower the pH level of the water. It is also known as dry acid, pH decreaser or acidifier.

When added to pool water, sodium bisulfate reacts with water to release hydrogen ions (H+), which lower the pH level. The reaction also produces bisulfate ions (HSO4-), which can help to control alkalinity levels in the water.

Sodium bisulfate is available in granular form and can be added directly to the pool water. It is important to follow the manufacturer's instructions carefully when adding sodium bisulfate to the pool water, as adding too much can lead to a sudden drop in pH level, which can be harmful to swimmers and pool equipment.

In addition to pH reduction, sodium bisulfate can also help to prevent the formation of scale and stains in pool water, as well as improving the effectiveness of chlorine sanitization.

It is important to note that sodium bisulfate is an acid and can be corrosive and harmful if not handled properly. It should be stored in a cool, dry place, away from other pool chemicals, and should be handled with appropriate safety precautions, such as wearing gloves and eye protection.
