Alkalinity increaser in powder, CTX-21, used to increase the alkalinity of the water when it is lower than 125 ppm. >Total alkalinity indicates the amount of alkaline components (carbonates, bicarbonates and hydroxides) dissolved in the pool water.
Alkalinity plays an important role in regulating changes in pH (buffer effect), meaning that if the alkalinity is not at values of 125-150 ppm there will be oscillations in the pH and pH stability cannot be achieved, which could give high or low pH values, causing problems of turbidity, scale or corrosion, eye irritation, green colouring of the water respectively.
Ideal for: All types of pools.
Prevents an imbalance of the water which causes irritation in the skin and eyes of bathers, corrosion in metal parts of the pool and excessive consumption of disinfectant.
Add 1.8 Kg of product to increase the alkalinity of 100 m3 of water by 10 ppm, with this figure being a general guide only.
The total alkalinity of the water should be between 125-150 ppm (CO3Ca), and it should be checked using a test kit once a week.
Pour the required dose of the product dissolved in water into the pool, and distribute this solution over the surface of the pool evenly.
