H2O pH minus is a chlorine-free granulate designed to lower the pH value of pool and hot tub water. Maintaining the ideal pH within the range of 7.0–7.4 is key to the full effectiveness of disinfectants and the comfort of bathers.
The granulated form dissolves quickly in water and distributes evenly throughout the entire volume of the pool. Dosing is precise and predictable: 100 g of the product per 10 m³ of water lowers the pH by approximately 0.1.
The correct pH value protects the metal parts of the pool and hot tub from corrosion and slows the fading of liners and plastic parts. The 1.4 kg pack is sufficient for repeated pH corrections throughout the entire season for a standard home pool.
