Increases total alkalinity and pH levels in spas. Also known as Sodium Bicarbonate, Buffer, Bicarb. Acts as a pH buffer to prevent extreme pH shifts. 

Ideal TA level is usually 80-150ppm. Low Total Alkalinity can cause damage to plastics, heaters, seals, and pumps. 

• 200g will raise Total Alkalinity by 10ppm per 10,000 liters
• 20g will raise TA by 10pp per 1,000 litres 
• (200gm will bring TA to 100ppm for 1,000 litres)
