    GH for years was pretty steady at 60. This year I added Epsom salt and calcium chloride to raise the GH to 107, to get the pH down from 8.8+.

    The difference in the pond this year is 1) more aeration (added an air stone to circulate water at bottom of the pond) 2) larger fish (3 are around 12", 7 are around 5-6") (As a reminder - my pond is 1,000 gallons.)

    Before adding any baking soda, Epsom salt or calcium chloride to the pond my readings were:

    For the rest of the year I have been maintaining KH at 107, GH at 107, and the pH has been steady at 8.4.

    I've seen ph as high as 9.6 in my pond visits, especially to ponds on well water. The fish appear fine even with a constant high level. There is the suggestion in the literature that high ph contributes to fish splitting. If the water comes from a city source, check their EPA report to see what they target and measure annually. If they target 9.6 I would just accept it or buy a water softening system.
