OK so all the fish you want to keep tend to be acidic, lower pH
preferring fish. But also, are not picky about water conditions. So
unless you were trying to breed them, these are fish that all will do
ok in most common tap water that avoids extremes.
To get back to your questions, if the wood lowers the pH and colors
the water, this will actually be greatly appreciated by the fish you
are going to keep. The water discoloration is a personal preference
and some people hate it while others try to encourage it. If you
don't like it, then yes, activated carbon will help remove the color.
But keep in mind you will have to keep replacing the carbon regularly
to keep the color away. But again that depends on the wood you get.
