Description

Interline pH-Minus 1 kg is a reliable and powerful powdered agent for lowering the pH value in swimming pools and spas. A correct pH value (between 7.2 and 7.6) is essential for the optimal effectiveness of chlorine and other water treatment products. pH-Minus helps to correct an overly high pH, which prevents problems such as cloudy water, irritation of the eyes/skin, and limescale deposits.

• Swimming pool volume formulas:

  • Rectangular: length × width × avg. water depth (in meters)

  • Round: diameter² × avg. water depth × 0.78

  • Oval: length × width × avg. water depth × 0.89

  • 8-shaped: length × width × avg. water depth × 0.85

In addition to pH correction, this product can also be used to lower the total alkalinity (TA) of the pool water, helping to keep the water balance more stable. Interline pH-Minus is suitable for all types of swimming pools and spas, for both private and professional use. The product is dissolved in water and then distributed evenly over the surface.
