Add soda ash in small amounts and test. repeat first action.

Muriatic acid works best to lower both pH and alkalinity, but thee's a way you need to do it in order to hit one without too much damage on the other.
While your filtration system is running and the water is circulating, broadcast, (don't dump the product or go too fast), the pool acid, or pH minus if you wish, into the pool starting in the deep end and working around the perimeter. Please remember to use goggles and heavy rubber gloves. If you spill any acid on your skin, it will probably eat through 3 layers of skin before you can wash it off. Remember, safety first.
Allow the water to fully circulate, usually 4-6 hours, then re-test your pool's pH balance.
Make another small adjustment if needed.
add a PH reducer chemical
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.
To adjust pH and/or lower alkalinity.
You have to know what you are doing. The addition of muriatic acid lowers the pH and total alkalinity in swimming pools.
No. You will also get a bad smell or odor from your pool water. Where did you get this idea????
my sack
raising the pH level of the swimming poolThe recommended pH-range for a swimming pool is between 7.2 and 7.8. To raise or lower pH, alkali such as sodium carbonate (soda ash) or sodium bicarbonate (baking soda) will added to the water. thanks hope it helps you heaps!!
To lower the pH of your pool from 8.2, you can add muriatic acid or sodium bisulfate. Follow manufacturer guidelines and test the pH frequently to ensure it is within the recommended range of 7.2-7.8 for swimming pools.
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.
Soda Ash
No it cannot. Sodium bicarb has a ph of 8.4. To lower ph you would need to use a dry acid (sodium bisulphate) or muriatic acid. City water is normally treated and has a ph of 7.5 but it would take a large amount of fresh water to lower the ph of a pool.
That Acid is called Muriatic Acid. You put it in your swimming pool to lower the PH of the water. At lower PH Levels, the chlorine you use to sanitize the pool is more active, as a disinfectant. You MUST be careful not to put too MUCH Muriatic Acid in your pool! PH that is too low will create potentially deadly fumes, so test your water. Low pH is corrosive to plaster and metal pool parst.
