Reduces alkalinity of swimming pool water (softens hard water)
Add muriatic or hydrochloric acid.
Most likely not.
Hydrochloric acid can be safely and effectively used in swimming pools to maintain pH levels by carefully following instructions for dilution and application provided by the manufacturer. It is important to wear protective gear such as gloves and goggles when handling the acid, and to add it to the pool water slowly and in small amounts to prevent sudden pH changes. Regular testing of the pool water and adjusting the acid dosage as needed will help ensure the pH levels are kept within the recommended range for safe swimming.
Hydrochloric acid is added to a pool to lower the pH level. Proper pH levels help maintain water clarity and prevent irritation to swimmers. It also helps in balancing other chemicals in the pool water and preventing the growth of harmful bacteria.
You can add dry acid to your pool when your pH is above 7.8
Usually you would add muriatic acid to adjust the pools acid level.
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.
As the pH of a swimming pool increases, hypochlorous acid converts to hypochlorite ion, which is less effective as a disinfectant. This leads to a decrease in the amount of hypochlorous acid available to sanitize the pool water. Maintaining the pH within the recommended range helps optimize the effectiveness of hypochlorous acid for disinfection.

It is safe to swim after adding hydrochloric acid to swimming pool. but in a small quantity like for a pool just a liter of dil. HCl (0.1N) . But if you use conc. HCl , then there may be chances of skin burn or blisters etc. to the skin. It mainly depends on concentration. and amount of water is added. DO NOT ADD conc. HCL to the water. There will the chances of bursting.
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.
