You can't!
Muriatic acid (~32% HCL) will not add any free chlorine to the pool and will not function as a oxidizer (Shock).
Yes you can the muriati acid is used to get the pools pH to between 7.2 and 7.6 then you can add the pool shock as per the instructions.
You probably didn't put enough acid in it.
pool acid is made up of muriatic or hydrochloric acid that is it.
liquid pool acid is Muriatic acid or more commonly know as Hydrochloric acid (HCl)
Yes, you can use muriatic acid to control pH in a pebbletec pool. Added correctly (spread around the pool with circulation equipment operating) muriatic acid will not harm the pool. As a matter of fact muriatic or hydrachloric is the best thing to use but I suggest you dilute it 4 parts water 1 part acid for safety to you and your equipment
The pH level of a pool can be lowered by using a specific acid that is sold at pool supply stores. The acid is called muriatic acid, and it should be added to the pool while the water is circulating. About 1/4 gallon of the muriatic should be added per .1 part per million the pH needs to be lowered.
Hardware stores, Pool shops.
Use muriatic acid.
muriatic acid
Drain pool and clean with muriatic acid
Both are lowered using muriatic acid or pH reducer from your local pool supply store. thepoolandspawarehouse.com
