Where to get Tufa rock?

[reefhawk]

"When I was planning to use tufa in my 150 I was going to get it from http://www.tufa.bc.ca, but I eventually decided against it due to the possibility of metallic impurities"

I know this guy personally and if you tell him its for your aquarium he will take special care. It is natuarally occuring all around the cheryville area of B.C.
