Low Total Alkalinity will cause "pH Bounce" allowing
the pH to easily rise & fall with slight additions of chemicals or environmental
debris. It will eventually lead to very low pH & acidic corrosion of pool
equipment & surfaces, including plastics & stainless steel. At very low
levels, the water is VERY clear. High Total
Alkalinity will lead to the pH being high with difficulty to bring it back
into a normal range & cloudy or hazy water. Left alone, high TA (over 175
ppm) will cause scaling of pool surfaces & equipment. Use PoolBoss pH Down
to effectively & safely lower High TA.
