Its fast dissolving, extra fine formula is made with a patented process that makes it perfect for weekly shock treatments and killing algae. No need for messy liquid chlorine for sanitizing your pool, HTH EXTRA is easier to store and use. 1 pouch is approximately equivalent to 10 liters of liquid chlorine

Features/Benefits:

  • Compatible with chlorine, ozone, mineral systems and salt water pools
  • Calcium Hypochlorite
  • Contains 75% available chlorine
  • Fast dissolving, extra fine formula - no need to pre-dissolve
  • Perfect for weekly shock treatments
  • Kills algae

Always test and ensure pH is between 7.2 and 7.6 before shocking your pool. Test your chlorine levels regularly, and use a shock treatment after heavy use of your pool or after rain fall, as rain water can introduce organic contaminants to your pool water.
