CTX 21 is a preparation intended for increasing the total alkalinity of pool water. Correct alkalinity in the range of 80-120 mg/l acts as a buffer system and stabilizes the pH value.
Low alkalinity causes instability of pH, which is then very difficult to maintain in the optimal range. The application of CTX 21 reliably solves this problem.
The granulated preparation is easy to dose and dissolves quickly. The 6 kg packaging covers the needs of a normal season for family pools with a volume of 20-50 m³.
