Product to increase alkalinity.
Correctly adjusted alkalinity is essential for a stable pH. If the water's alkalinity is between 100 and 150 ppm, the pH will remain stable.
Dissolve the product in a bucket of water and then spread it over the water surface.
150g of product in 10m³ of water increases alkalinity by approximately 10 ppm. Never use more than 300g per 10m³ of water per treatment.
