Application Instructions

1. Maintain pH level within the ideal range of 7.2 – 7.6. If outside this range please use our PH plus or PH minus products to adjust for the best results.

2. Maintain free chlorine residuals for spas within the range 3 – 5mg/l (ppm).  For swimming pools it should be 1 – 3mg/l (ppm). Freshly filled spas require an initial start up dose of chlorine.

3. This product may be applied directly to pools or spas where temperatures exceed 20  degrees C. If below this temperature or in doubt it is recommended to pre-dissolve in a clean plastic container at a maximum rate of 10g of product per 0.2 gallons (1ltr) in water. Stir well to ensure product is fully dissolved. Add the resulting solution to the spa or pool whilst the pumps are turned ‘on’.

4. Repeat dose application if necessary to achieve the required levels.
