Which is more dangerous, high or low pH?
If you want a chat call me at xxxxxxxx. (Singapore).
pH 10 to 7 within in a short time is bad for the fish. Did you add anything else? Is the kiddy pool water new water as well?
Koi could take pH up more then pH down swing. But 30% water change is very normal, it should not bring the pH that far down. Check the water again.
