Lower pH

[VTwinFanatic]

Okay My question is what is the best way to lower pH w/o changing water Hardness? I know drift wood, and inject CO2, but is there any other ways?

Why do you want to lower your pH? Unless you are planning on breeding a difficult species of fish, it's usually not necessary.

And changing the pH without changing the KH or TDS is impossible other than by CO2 injection. The KH and TDS control pH.
