I was at PetSmart today, and I found a small package of "Mac's" grape driftwood. It is packaged for use in a reptile tank, but it doesn't say if you can/can't use it in an aquarium. I asked the salesclerk, and they had no clue. I have a rubbernose/bulldog pleco, and I wanted to get some driftwood for him. If I boil this all day long, do you think it would be safe to use. The package just says that it is heat treated, and a product of the USA.
