Easy to use with clear dosage instructions, it’s a BISHTA-approved product trusted by leading spa brands for safe, reliable water treatment. ## Description From the manufacturer ClearWater 1kg pH Plus/pH Minus is the best way to adjust a hot tub or pool's pH levels. Incorrect pH levels can impact the water quality and the experience for the user. The recommended pH balance is between 7.2 and 7.6. When pH levels drop below 7.2 acidity increases and pH increaser is needed. Applying the pH water treatment couldn’t be simpler. After dissolving the recommended amount of pH chemicals in warm water you simply add the solution to the water and this will increase the pH level. After a minimum of 4 hours, pH levels should be checked again and increased or decreased accordingly.
