In areas of soft water it will be necessary to add Alkalinity Increaser to the water. Water that is low in alkalinity can cause corrosion to pumps & heaters. Alkalinity Increaser will prevent this & it will also slowly increase the pH of the spa water.
1. 1 teaspoon will increase the alkalinity level by 2.5ppm in a 1,000 litre spa.
2. Dissolve in 2 litres of warm water and pour into spa.
3. Turn pumps on for 5 minutes
4. Test with testing strips and repeat dose if necessary.
