I’m guessing it would be best to work with the cards you were dealt as far as PH. If it keeps rebounding, there is a waters source that will just keep overwhelming your adjustments. You would need to line and isolate your pond to prevent this from happening, and that may not be practical. There may be potential to use actual acid, like HCL, in a slow drip to compensate, but that seems more trouble than anything.
But first, understand where that is coming from and see if it can be controlled. A spring? Runoff?
