so i water with tap water, and the pH is waaayyyy high
and when i add acid to drop the pH, i think it ends up rising over a few days.
does anyone have any experience/advice?

You should add 1 tsp.. Dolomite Lime (crushed) per 1 gal of soil. You can buy it in fine powder or granules at any plant nursery, HD or Lowes and some of your local stores.
If in granules you will want to crush it into sandy powder first. Then add the ratio above to the top of your soil and mix it into the top 1/2 inch. Then water with plain water as close to 7.0 pH as you can. The Dolomite lime is used as a PH buffer and helps keep your soil PH around 7.0.
Let your soil dry out and check your PH of your run off water. If it is still high then add more dolomite lime in the same amount as above and water again.
Your PH will buffer and you will stop having a high PH.
Good Luck!
