HTH® GRANULATED DRY ACID 3KG

HTH® GRANULATED DRY ACID 3KG

INDICATIONS:

  • Lowers pH levels
  • Works as liquid acid. 

 

INSTRUCTIONS FOR USE*. USE ONLY AS FOLLOWS:

*based on a 50 000 L swimming pool

 

TO LOWER PH LEVELS:

  1. PH levels should be kept between 7.2-7.6 to ensure effective sanitation, avoid skin and eye irritation and prevent swimming pool linings and equipment damage; 
     
  2. Test the pH level;
     
  3. With a working filter, add 250g (half a full lid) of HTH® dry acid on the swimming pool borders; Note that in the case of vinyl or canvas coating, pre-dissolve the HTH® dry acid in a bucket of water before adding it to the pool.
     
  4. Filter for 3-4 hours, test and readjust pH level if necessary;
     
  5. If the pH level is still too high, continue to adjust downwards within the required range of 7.2-7.6. Never add more than 500g at a time.

 

TO REDUCE TOTAL ALKALINITY (TA):

  1. Turn off the pump;
     
  2. Pre-dissolve 250g of HTH® dry acid diluted in 5 litres of water and pour onto the deepest point of the swimming pool;
     
  3. Leave the pump off for 15 minutes;
     
  4. Turn the pump on and continue with the normal filtration process. Check TA levels after 12 hours;
     
  5. If necessary, repeat the process until the desired levels are reached. Never add more than 1kg of HTH® dry acid at one time. 1kg diminishes TA to 10ppm on 50 000L.

 

FIRST-AID:

  • Skin: brush excess chemicals and rinse with cold water for at least 15 minutes. If irritation persists, seek technical assistance;
     
  • Eyes: wash with cold water for at least 15 minutes. Seek medical assistance.
     
  • If inhaled: the person should get fresh air. Seek medical assistance;
