dry acidDirections for use:

(Based on a 50 000l pool)

Use only as directed.

 

To Lower pH

  1. pH should be kept between 7.2 - 7.6 to ensure effective sanitation, avoid eye and skin irritation and prevent damage to pool linings and equipment.
  2. Test pH level using HTH Quick Test Strips or HTH 4 in1 Test kit.
  3. With the filter running, add 250g (½ capful) of HTH® Dry Acid around the sides if the pool.
  4. Filter for 3-4 hours, test and readjust pH if necessary.
  5. If pH is still too high, continue to adjust down until within the required range of 7.2 -7.6

 

NB: Never add more than 500grams at a time.

 

In the case of a vinyl or colored lining, pre-dissolve HTH® Dry Acid in a bucket of water before adding to the pool.

 

To lower Total Alkalinity (TA)

  1. Switch the pump off
  2. Add 1KG of HTH® Dry Acid diluted in 5 liters of water, then Pour into one spot in the deep end of the pool.
  3. Leave the pump off for 15 minutes
  4. Switch the pump on and continue with normal filtration. Check the TA level after 12 hours.
  5. If necessary, repeat the process until the ideal range is reached

 

NB: Never add more than 1KG of HTH® Dry Acid at any one time. 1KG drops TA by 10ppm in 50 000l
