Nothing that you added should have affected the GH. The GH test kit that I
have is almost impossible for me to run, due to the colors green to yellow,
or vice versa. There just isn't much definition, like there is with KH.
Don't worry about the small difference in the test results. Don't add
muratic acid, it just eats the KH.

My GH test first colors the water red, then changes to green with one drop.

Since I posted last night, I've googled rec.ponds on GH and KH, and read
up on making the changes. Seems that if I keep adding baking soda my pH
may go up or down to 8.4 and hold there when the KH reaches a level of
110 ppm or so.

Will keep y'all posted.
