Carefully take care that you don't splash any in your eyes. A good way is to work out how much you need carefully measure it into a bucket, then take the bucket to the pool and lay t in the water the acid will run out with no splashing that way. Just use common sense.
pool acid is made up of muriatic or hydrochloric acid that is it.
You can't! Muriatic acid (~32% HCL) will not add any free chlorine to the pool and will not function as a oxidizer (Shock).
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
