good stable acid to use for PH control

What is a good stable acid to use for PH control. Ive heard that muric acid works. How about sulfuric acid like used in hot tubs.Id like to know your opinion Ron. Thanks23

I use General Hydroponics Up which is phosphoric acid, citric acid, and ammonium bisulfate. And pH Down that is potassium carbonate and potassium hydroxide but I don't know at what proportion or I would mix my own.
Any chemist out their want to try?
