And let's not forget the importance of checking water quality FIRST, and
if
there is ammonia showing YOU MUST treat that first before doing a water
change.

Doing a water change with a possible higher pH than the pond makes the
ammonia even more toxic. So as Ingrid put it, everyone should have Ammonia
locker upper on hand.

What I'd like to know is, what is/was the KH of the OP's pond? ~ jan

I concur...I have a gallon of it, stored right next to the pond.
