The pH can be anywhere from about 7 to 9 with a little tolerance either
side. What is more important is the stability of the pH. If the pH is
jumping up and down, morning and evening, then the fish are being stressed
and stress causes disease. I don't run the pH, because I feel a test called
KH (carbonate hardness) is more important. If the KH is up, the pH will be
stable. I don't like to see a pond have less than 4 dH or 70 ppm, and the
higher the better for the filter bacteria, up to at least 300 ppm.

I was wondering what a good pH for Goldfish are? I just purchased a pond
testing kit and got a pH of about 7.8. Is this good?
