Portland does contain a lot of lime. However, I've used it with success in turtle, fish, and crocodilian exhibits with no aparent trouble. It does leach out eventually and there are ways to speed that process up. Unfortunately I don't remember them at the moment and my books/notes on the matter were lost in a flood this fall.



Thanks for the link. I look forward to reading it when I get on a faster service.



You might also consider plaster mixed with those little styrofoam beads found inside of bean bag chairs. That will provide some texture and reduce the weight. I suspect it would be easier to seal that the mixture you mentioned but that's an uneducated guess on my part.
