How big a pond Rick, and what was the pH before adding BSoda?

I've got a 1000 gallon lily pond registering 9.0, I added 4 lbs of BSoda
over 4 days and had a pH of 9.0-9.2. ~ jan

Dave, KH is a function of pH. Nothing wrong with either. Do not try to
fight the ph. It is a losing battle. I personally keep my KH greater
than 120 ppm. This promises a ph of 8.3 or 8.4. Almost no need to test.
I don't anymore. I only adjust my KH with 12 lb bags of baking soda.
