I want to get a green spotted puffer, and my ph level is about 8. In the tank I want to get some drift wood. I know real drift wood discolors the water for a time and slowly softens the water. I was wondering if I got fake driftwood (plastic stuff) if cleaning it in a brackish tank is any different than in a fresh water one. Any oppinions about what type of driftwood to get would be great.
