This product is used to decrease the pH of your pool water. Proper pH control of pool and spa water is essential to eliminate problems caused by pH being too low or high. If pH is too high the water becomes uncomfortable for bathers. Add this product if your test kit result indicates that the pH is too high.
Directions for use:
Test the pH of your water on a regular basis. The pH of your water should be
maintained between 7.2 and 7.8 with an ideal reading of 7.4. This will allow most
effective use of other swimming pool chemicals. If the reading is above 7.8, add this product at the rate of 500gm per 45m³
Pre-dissolve the granules into 10 litres of water, using a clean plastic container and
mix carefully. Slowly pour the solution into the pool water near to the return inlets
and rinse container out thoroughly.
To obtain maximum benefit from the chlorine, the pH of the pool & spa water should be maintained around 7.4 and between 7.2 & 7.8 at all times. Above 7.8 the efficiency of the chlorine will be reduced.
