The Beachcomber RESIST™ 500g is a granular alkalinity increaser that also contains sodium bicarbonate. It helps hot tub water resist fluctuations in pH levels by increasing Total Alkalinity levels.
Aim to keep a proper Total Alkalinity level at a range between 100-120 ppm.
Available sizes: 500g & 2kg
Total Alkalinity is the measure of the amount of alkaline salts in your water. It helps hold pH level stable at around 7.2-7.8. If Total Alkalinity is high, the pH levels will go higher and vise versa. Out of range alkalinity levels results in very unbalanced water condition. This can cause damage to concrete pool surfaces, light rights, copper heater elements, ladders, dials and stainless steel fittings.
