I think what you meant to say was that 'pH is hard to control if the
buffer level is too *low*'. A high buffer makes your pH very stable
(hard to change but very stable ;~).

if I understood correctly..

pH is hard to control if the buffer level is too high (KH), so deal
with
that 1st. Read these pages and maybe this will get you pointed in the
right
direction.

A word of caution, make any water changes SLOWLY. The slower the more
stability you will have in the total water chemistry

| Boy, I'd love to buy an RO unit, but the price is no-where near my
range.
I haven't tried rainwater yet, next time it rains, I'll certainly give
it a
shot. I bought one more pharmaceutical from the LFS guy, who said that
he
almost sells more of it than he does fish. It was Proper pH 7.0 by
Aquarium
Pharmaceuticals. It took about a triple dose to do it, but it lowered
the
pH and kept it at 7. A knew problem has arisen though. It removed all
of
the hardness from my water. Will it be possible to regain hardness
without
increasing pH? I bought a really nice test kit, and my pH in untreated
water runs 9.8.. The kH runs 35 degrees. Well, I appreciate the
help.
