pH Minus 1kg

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.
