General muriatic acid (31.45%) addition question - is there a practical limit to how much acid you can add to pool within a given time period? I seem to remember reading somewhere on another site that you can't down adjust your pH too quickly with a large acid addition without risking damage to your pool.
For example, let's say you use my 17k gallon pool and I'm at a pH of 7.8 and I'd really like to be down at 7.0 to reduce my TA through acid/aeration process (assume my other parameters like FC/CC/CYA are all good). Based on previous acid demand tests and PoolMath, I'd be adding something like 2 quarts + 2 cups of 31.45% MA. Obviously one would add that much acid very slowly in front of a return and perhaps do a good brushing to ensure proper agitation.
Can I really add that much acid to the pool and/or practically drop the pH that far without seeing some serious pH rebound or possibly damaging walls and SWG's? Is it better to dilute and broadcast around the pool or break up the additions with some wait time in between? Just trying to get a feel for a good methodology
