Food Grade 85% .. insanely strong when not diluted.. you can dilute 5 to 1 water to acid or 10:1 water to acid easily. I have put rusty bolts in the undiluted and they come out like they were sandblasted in about an hour.. the threads all cleaned out like new.

or you can buy a quart of rustmort which i always use to use as an autobody tech .. its great .. I would say its probably a 10:1 dilution

Other than perhaps wanting to dilute a bit to get the sulfate down with some beers you can make that water work. My water is fairly similar (though I don't have quite as much sulfate) and my tactic is phosphoric acid to get my pH in line since it purported to be more flavor neutral than lactic. Due to how much I need to add I use 85% phosphoric. https://www.amazon.com/Gallon-Grade-Phosphoric-Remover-Clean/dp/B06XZSW3QX
I use Bru'n Water for my calculations and after many brews of my mash pH being right on I trust it completely.
Let’s see.

will last you a while (notice it's 85%), so 8.5 times more potent. Acid malt is also not that much more expensive than regular malt, about $2 per pound vs $1 for regular malt and I would usually use 1/2 pound for corrections, so comes to 50c per 5g batch - I don't think it's worth the effort with the sparging.
