Hi Susan,
I have used vinegar (acetic acid) to lower the pH of water used for
orchids. If you don't have a pH meter, you can use pH test paper or a
kit from an aquarium store. I don't think the carbon in acetic acid
will harm cp's since they grow in a carbon rich environment.

Vinegar has been used to lower ph of CP water for quit a while. I have also
used vinegar water for years on Sarrs and VFTs. If using vinegar, use only the
white distilled vinegar. Start out by adding several drops to a gallon of water
or equal. Take readings after each mixing and keep records. I have used up to a
table spoon per gallon without any side effect. One long time CPer, I know,
always adds vinegar and an air stone to the water that his CPs sit in. He claims
it helps to control the growth of algae and stimulates plant growth by adding
needed oxygen to their roots.
