Invest in some calcium hypochlorite. One pound purifies 10,000 gallons.
Looks a lot like ours. (Your "holding tank" is a mate to ours -- I assume it's a settling tank; can't think of any other real function for it).
Here's what I use for the pH adjustment: https://www.amazon.com/gp/product/B002WKM4A0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
Same sized tank, and I use 2 teaspoons for each fill, though your mileage may vary, depending on your starting pH and pump I suppose. I think each teaspoon makes the equivalent of a gallon of bleach (I need to find a source for that, but that's what's in my head).
Still pretty readily available in the northeast for me, but you can get it cheap from Amazon from a number of vendors.

Is a good example. 6 lbs for 33 bucks plus shipping is essentially 60k gallons of water. You can probably find it in cheaper or smaller quantities, I just grabbed the first thing I saw.
