ok so i got a ph tester
test said my pond was 6.0 or lower
i searched google and most say koi need 6.8-7.2
so im going to add ph up to try to raise it.
could this be the reason for fin rot?or does it have to be high ph to do it?

The effects are only temporary. Once it wears off, the pH will swing out of control. Maybe get some calcerous rocks.
no clue what that is lol
ok so the chem is still ok for now.
i gotta raise it before the koi die.

Crushed and baked oyster shell is also a good way to raise pH, it is cheap and available through seed and feed stores as a calcium supplement for chicken feed. It runs a few bucks per 5lb bag or less.
While fin damage is usually a symptom of high pH it can also be caused by low pH.
Before treating the pond check your baseline pH at the water source. If it is not low then your water is being acidified in the pond itself. Excess detritus or mulm can cause this as can rotting tree leaves. One other source of acidity that I have run into is acidic rocks, I once used Montana Gravel as a substrate and it dropped my pH to something like 5.8.
