One I got my high alk in line, it was time to add more water due to evaporation losses. This shot my alk right back up of course, since my fill water alk is 320 ppm It's a viscous cycle that seems to have no end, and I'm contemplating just ignoring alk and enjoying the pool.

PH is again at 8. Pool is crystal clear. I don't have a heater or SWG, and pool is IG vinyl. I don't use calcium, and haven't for a long time.

What am I risking if I let the alk stay high and just try to keep PH below 8 by using acid as needed?
