I agree 100% with Fishfirst. We have quite hard water here, and the pH is naturally 7.8. There are lots of fish we can keep in this without any problems.

Adding plain acid is a *really* bad idea. Once you've used up all your buffering and the pH starts to drop, you'll have wild pH swings which is *very* bad for your fish...
