a ph of 7.0 is best for freshwater fish. But anywhere from 6.6 to 7.4 is fine.

 

Goldfish are super hardy and super filthy 7.0 is ideal but you can get away with anywhere from 6-8 Ph. Are you keeping them in a tank with filtration or in a bowl. Most freshwater fish are not nearly demanding as saltwater basically declorinated tapwater will work just fine<either chemically or set aside for 24 hours> the only truly fussy or demanding fish that I can think of as far as PH goes are of the chiclid family and mainly those that are south american ie, discus and angels. If all you are keeping are goldfish be prepared to do weekly water changes because they are detrius machines and they stink....BAD.
