You lower the Ph by using Muriatic acid VERY carefully. This acid and it's vapour is dangerous. With the pool pump ON, carefully add 1/4 gallon at a time, waiting 6 hours then testing.
To lower the pH level in a pool, you can add pH decreaser or muriatic acid according to the manufacturer's instructions. Test the pH level after adding the product and adjust as needed until the pH falls within the optimal range of 7.2-7.6.
Using sodium bicarbonate to lower pH in a swimming pool is not effective. Sodium bicarbonate, or baking soda, is typically used to raise pH levels in pools. To lower pH in a pool, an acid such as muriatic acid or sodium bisulfate should be used.
add a PH reducer chemical
Muriatic Acid....Be real careful though.
Shocking a pool with products like chlorine can actually lower the pH and alkalinity levels of the pool water temporarily. It is recommended to test the water and adjust the alkalinity levels if necessary after shocking the pool to maintain proper water balance.
Baking soda will almost certainly raise the pH level in a pool.
It depends on the pH level in the pool and the gallons of the pools, also how many ppm you want to lower it.
use muratic acid to bring down Ph and TA
To lower the pH from 9.2 to 7.2, the worker should add an acid, such as muriatic acid or pH decreaser, to the pool water. She should follow the manufacturer's instructions on the product to gradually lower the pH level, frequently testing the water until it reaches the desired pH of 7.2.
Add potash. See your pool shop with a sample of your water and the size of your pool and he will give you what your pool requires.
It is used to lower both ph and alkalinity.
To adjust pH and/or lower alkalinity.
