Actually, I AM using pressurized CO2... I have some drift wood that's keep
my pH LOW, so I use Alkaline Buffer from SeaChem to "up" the pH.. (It's
plant-safe).

Are you using CO2? Are you using anything else to adjust the pH? The
levels you have are fine for most fish. If you are not using pH
adjusters then you are running about 8.5 ppm CO2, which may be low
depending on how heavily planted the tank is and how much light you are
using.
