Resist (500g) – Alkalinity Increaser


eachcomber Resist is a finely ground granular product that contains sodium bicarbonate. It raises the Total Alkalinity (TA) level in your hot tub water to prevent pH bounce, corrosion, scaling and staining. Total Alkalinity in the proper range (100-120 ppm) maintains the correct pH, makes the water ‘resist’ changes in pH and increases the effectiveness of the sanitizer.


  • Test Total Alkalinity level (correct range : 100-120 ppm). Beachcomber 6 Ways Water Test Strips
  • To raise Total Alkalinity by 10 ppm, add 18g per 1000 L
  • Add Resist to the centre of the hot tub


RESIST™ helps water to resist changes in pH, and increases the total alkalinity of hot tub water to prevent pH fluctuations. Maintain a proper Total Alkalinity (TA) level of 100 – 120 ppm
