Driftwood In Which Tank?

[MegTheFish]

I wanted to buy some nice pieces of driftwood for one of my tanks but since it lowers the pH of the water I don't want the fish to be negatively affected by it. So which tank holds fish that like a lower pH, and that will benefit from it?
50 gallon- bloodparrots, jellybeans, yo-yo loaches
55 gallon- tetras, cories, loaches, angels
20 gallon- goldfish, weather loaches

Thanks

the fish in the 55 gallon would benifit most out of all your fish
