Acid lowers the PH number. You want the pH to be between 7.0 and 7.4. To raise the ph you can use baking soda.
No it reduces it
The only way to lower your cya level in your swimming pool is to partially drain your pool and fill with fresh water that will lower it or if you want to lower it to almost nothing completely drain your pool and start over but keep in mind chlorine tablets will raise your CYA level More information in the related link below.
To raise the pH of your pool you add soda ash (sodium carbonate). To lower the pH of your pool add muriatic acid (hydrochloric acid) or sodium bisulfate. You should always add chemicals with the pump running and check your levels again once the newly added chemicals have been circulated around the pool.
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.
Add acid
Sodium bisulfate (AKA sodium hydrogen sulfate or sodium acid sulfate) is an acid that will lower pH. If you lower the pH of a swimming pool buffered with baking soda (sodium bicarbonate) and maybe cyanuric acid (stabilizer), your alkalinity will go down, along with the pH. But usually, what people want is to lower the alkalinity (or TA) without lowering the pH. When you lower the pH on a carbonate buffered pool, you convert some of the carbonates into carbonic acid, where they no longer contribute to the measured alkalinity. But, as soon as you raise your pH, the carbonic acid switches back to carbonate, and your TA goes right back up with the pH. To actually LOWER the alkalinity, you have to lower the pH, and then REMOVE some of the carbonic acid, which you can do be aerating the pool, since carbonic acid is a form of carbon dioxide gas.
1-2 gallons of muriatic acid will break down the buffer solution(alkalinity in the water). Will then probably have to raise pH back up
Muriatic Acid....Be real careful though.
No, adding Muriatic acid will lower the pH value. If you want to raise pH numbers use baking soda and/or soda ash. Test it the next day, after it has a chance to mix evenly using an OTO tester and try to hit a pH of 7.2. Hatawa
Hydrochloric acid is most commonly known as muriatic acid and is used to lower pH in pools
Add acid, Muriatic acid works best but Dry Acid is also used.
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.
Remove some water in container (10-20%) and add new water. example: pump water high in cyanuric acid out of a swimming pool and the add fresh water to the pool.
