Thanks Kay.  The Cornell site is great thanks!  I did misspeak, I added a
neutral pH regulator not a buffer.  So far today the pH has stayed around
7.5 so perhaps the buffering capacity is finally beginning to be

I'll have to go check our natural ponds and the creek to see what going on
with them.

The buffering maybe why I've had trouble with the yellows in some of my
potted plants.
