More water questions

I have super soft water, had analisis done in Madison. No copper but has aluminum, all are way under water guidelines. And I treat with reptisafe, it is coincidered spring water, but it is too soft, and low ph, especially after adding reptisafe! So I've added ph up to get it above 7.2 . But want to add aquarium salt to get it up in hardness, since it's below 25, normal is 75 to 100. So should I do all this to get it into normal levels, or is ph of 6.5(acidic) and super soft water ok? I've read and re-read article labled, all u need to know about water, and still in doubt

so any one. Should I not worry about it being to acid or too soft? How would I add salt to harden, and is that right? I thaught salt softened hard water? But acording to local pet store I should add salt? Confused
