Wizards Alkalinity Builder is a rapid dissolving powder used for increasing the total alkalinity of your spa / hot tub or pool water.
Aim for an alkalinity level of between: 120 – 150mg/l in your spa water.
We recommend that you pre-dissolve the product in a clean plastic container (rate of 10g per 1ltr water), in clean water. Stir well to ensure product is fully dissolved. Add the resulting solution to the spa whilst the pump(s) are turned “on”.
