pH Minus 1kg
When the water is more alkaline, pH Minus is used to decrease the pH
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 7.4 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 than 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
The Spa water should always be tested 30 minutes after treatment.
