Description
Hot tub water with very low pH (acidic water) can cause corrosion of your equipment and staining on the tub surfaces. It can also be very unpleasant to bath in.
In addition many sanitisers do not perform efficiently if the pH of the water is not maintained within a specified range.
To raise the pH of spa water add 10g (or approximately 2 teaspoons) of granular product (such as AquaSPArkle Spa pH Plus) to a litre of warm spa water and add the resulting solution to the spa whilst the pumps are turned on.
