I guess in all the years I've used tap water and didn't know the pH I never had any problems with my fish. There was the occasional ick to deal with and fungus, but the probable high pH didn't seem to hurt any, so I'm with Spongebob and Coler on this.

Try doing a 30% water change with only distilled water, or buy 1 gallon of spring water and test the pH. The distilled water should be only be used to do 1 water change to dilute the water in the tank. Don't keep using only distilled as the tank needs the minerals in regular water. Either that or get 1 gallon spring and check it's pH. If it's good or around 7 she can do 100% of the 30% water changes with it. Sorry to hear about these fish! Smaller tanks are more difficult to keep balanced. She should do daily 30% water changes if ammonia and nitrites are measurable, and nitrates are over 30 ppm. Nitrates should normally rise over time, but up to 30 isn't critical. It should be less than 10 ideally.
I've read that it's better to add the correct pH water than to add a pH lowering buffer.

Anyone else have any ideas?

i know ph dosent matter but she dosent want it that high she wants it lowere so ill see what happens

so take all that water out and maby ill give her my tap water? my water is fine will try , ya it realy sucks i toled her dont give up so will try over the weekend ill let u guys know how it went thanks again for all ur help and time really thanks.
