Yes as long as there is wter in the pool first.
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
Hardware stores, Pool shops.
Use muriatic acid.
muriatic acid
Drain pool and clean with muriatic acid
Yes there should be no problem with that.
Muriatic Acid....Be real careful though.
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.
None until you add it.
