Product Use and Application

Evopure pH increaser is necessary when the pH in the swimming pool or spa is reading low, but the total alkalinity is within an acceptable range.

If the pH is very low, it is important that pH increaser be added as per recommended dosage instructions and not exceeded, with a minimum wait period of six hours between additions. Retest ph between additions and add further doses as necessary.

When using Evopure Stabilised Chlorine,Evopure Stabilised Chlorine Tablets or Evopure Multi Action Tablets as the primary sanitiser, it is often necessary to increase pH levels due to the downward pull on the overall pH of pool water.
