Beachcomber Resist 2kg


The Beachcomber RESIST™ 2kg is a finely ground granular alkalinity increaser hot water chemical product containing sodium bicarbonate. It is used to increase the level of Total Alkalinity in your hot tub to prevent your pH levels from going out of range which can lead to staining, scaling and corrosion. When hot tub water Total Alkalinity levels are within the proper range (100-120 ppm) hot tub water is better able to resist fluctuations in pH levels and improves the effectiveness of the sanitizer.

Available sizes: 2kg & 500g

Beachcomber RESIST™ 2kg helps to maintain and minimize changes in pH levels. To prevent pH fluctuations, RESIST™ increases the Total Alkalinity (TA) of hot tub water.


  1. Increase Total Alkalinity with Beachcomber RESIST™
  2. Lower Total Alkalinity levels with Beachcomber pH Minus
  3. When water is balanced, pour Beachcomber Soft to keep parameters stable for an extended period


  • Use Aquacheck 6-in-1 Water test strips, measure the Total Alkalinity levels in the hot tub (Proper range is between 100-120 ppm)
  • Add 18g of Beachcomber RESIST™ for every 1000L of hot tub water to increase Total Alkalinity by 10ppm
