I didnt mean to imply that all houses have copper pipes, and to be honest, I dont know if that was even a metal used in pipes, but that was what I was told. I know lead was used in some really old homes in the US at least, so sorry if I misquoted anything there.
And also, not trying to defend the use of live sand or not using it, but most of the stuff in my live sand, can also be found in cured live rock. I just dont want anyone to think it is completely useless and a bad thing.
