I am in the process of desigining a fish room in my basement. I will need to construct the walls and all the rest that goes with that. I am concerned with humidity. Are there building materials that I can use for teh walls in the fishroom that will hold the humidity in and not let it into the rest of the house. Maybe I am thinking about this incorrectly but I am thinking if I can build the room out of materials that will not be damaged by humidity and keep the humidity in the fish room out of the house I wont have a mold problem?
Thanks
Eric
