HTH® Xtreme Flocc is a powerful coagulant developed to clarify severely cloudy water. The fast acting active ingredient, aluminium chlorohydrate, allows suspended particles to drop to the swimming pool floor to be removed by manual vacuuming.

  • Clears severely cloudy water
  • Drops suspended particles to pool floor
  • Requires manual vacuuming



Directions for use:

All dosages are based on an average pool with a capacity of 50 000 liters.

Adjust according to your pool size, regional variations, and weather conditions.



Never use more than the recommended amount of HTH® Xtreme flocc at a time, rather repeat the treatment after one week.



  1. Ensure that your pump, filter, and pool cleaner are in good working order and that the multiport valve is not leaking.
  2. Top up your pool level.
  3. Check and correct the pH level.
  4. With the pump on circulating/re-circulate or bypass, pour HTH® Xtreme Flocc and HTH® Metal Remover around the sides of the pool.
  5. Run the pump for 12 hours.
  6. Switch the pump off at the main switch for 24 hours to allow the sediment to settle to the bottom of the pool.
  7. With the filter set on the waste position, restart the pump and manually vacuum the pool slowly until all the visible sediment is removed from the floor of the pool.
  8. Once your pool is clear, backwash and rinse the filter thoroughly.
  9. Resume normal filtration and chlorination routine.
