thanks for the replys, I think I will end up going with wood (not for sure yet though)
kind of in a hurry to get the tanks up and running to get them cycled. The house should be done by the end of next week. I will then need to get everything out of our old house as soon as possible since the guy who bought it is letting us rent it back from him. dont want to have to pay another months rent for the fish to live there...
