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.
