Use pH Plus to increase the pH when the water is acidic (when the pH is low)
PH Increaser Sodium Carbonate and Soda Ash
There are two basic reasons for chemical treatment of your spa water:
The pH of your Spa is to measure how acidic or alkaline the water is. The pH is measured on a scale of 0 - 14, a pH of 7.0 is neutral.
When you test the spa and there is a pH reading of below 7.0 this means the water is more acidic than alkaline, this can cause various problems such as:
- Sanitisers to dissolve more rapidly
- increase corrosion of surfaces and equipment
- may cause eye and skin irritation
If the reading is higher the 7.6 it means that the water is more alkaline which can cause different problems such as:
- sanitisers such as chlorine to be less effective
- will produce scaling on the surface of the equipment
- cloudy water
- shorter filter runs
