CTX 700 is a special chemical product intended to eliminate limescale deposits that form in pools with hard water at an unsuitable pH.
It effectively breaks down limescale build-up on walls, in pipework and on filters, while at the same time reducing the iron content in the pool water that causes rusty discolouration.
The dosage is 2 litres of product per 100 m³ of pool water; the product is applied directly into the filled pool with the filtration running.
To prevent new deposits, we recommend regularly maintaining the pH within the range of 7.2–7.4 and carrying out control tests of the water hardness.
