Yes there should be no problem with that.
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.
In order to not cause irritation of the eyes and skin, the pH of the pool water should be between 7.2 - 7.6. Muriatic acid is added to the pool to lower the pH if it is too high.
pool acid is made up of muriatic or hydrochloric acid that is it.
You can try the following cleaning solutions; muriatic acid, bleach solution and battery solution.
You can't! Muriatic acid (~32% HCL) will not add any free chlorine to the pool and will not function as a oxidizer (Shock).
