This treatment is recommended for sand filters only.
Ensure that your pump, filter and pool cleaner are in good working order and that the multiport valve is not leaking
Top up your pool level
Check and correct the pH level with HTH ® Dry Acid or HTH ® Easy Acid
With the pump on circulate/re-circulate or bypass, pour HTH ® Xtreme Flocc and HTH ® Metal Remover around the side of the pool
Run the pump for 12 hours
Switch the pump off at the main switch for 24 hours to allow the sediment to settle to the bottom of the pool
After 24 hours and 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. Remember to top up the pool at the same time as you are manually vacuuming so that the water level does not drop below the weir.
Once your pool is clear, backwash and rinse the filter thoroughly
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.
