Algae Problems

pH Bounce

pH is a measure of the amount of acid or base in solution. Adding acid lowers the pH. Adding base raises the pH. Adding too much acid one day may require adding base or pH Down the next day. This up and down cycle is referred to as "pH Bounce"
Total Alkalinity buffers or absorbs both acid and base in pool water preventing "pH Bounce". Therefore, increasing the amount of Total Alkalinity can improve this situation. The exact amount of Total Alkalinity depends on the Saturation Index, type of sanitizer, temperature, whether it's a spa or pool, stabilizer and other factors but normally it should be somewhere between 60 and 180 PPM

TREATMENT:
Test all water factors and balance water. See Water Balance/Saturation Index.
