Thanks everyone for the advice. I'll give a little
more info as to what I'm looking to do: In the
established tanks, the water stays-in-high pH even
with the fish load. Perhaps this is because I have a
lot of plants (which are my main interest). The
plants would like higher KH/GH than 2, so I want to
raise it. BUT, if I raise it to where I want it, the
pH goes even higher, to about 9! I do have plenty of
fish in the tanks, and have soil underneath the gravel
(yields CO2). I do not wish to do CO2 injection
(PITA). So, how do I raise the KH/GH and keep the pH
from skyrocketing? David - doesn't peat soften as
well as lower pH?
