Description
pH is the measure of how acid/alkaline the pool water is. If pH is too low, the water can be corrosive to pool equipment. If pH is too high, then the chlorine becomes much less effective for sanitization.
Caustic soda (sodium hydroxide) is highly corrosive chemical which is often used to raise the pH in larger pools. This chemical is pumped into the recirculation system at a controlled rate.
Caustic soda is stronger than soda ash. … Caustic soda has the advantage of mixing to a clear solution and generates a considerable amount of heat when it’s mixed with water.
