Tufa Rock

[NanoN00b]

I doubt J&L will ship rock for the $100 deal. It's on dry goods only, not even lamps.

Tufa can be sourced from eastern BC in Alberta. There is a fellow who mines it for rock garden builders and the horticultural market. I recall near Sparwood?

Anyways, I'd recommend buying it at $4.50/lb or driving to Calgary for a day.

Tufa seems like a rock that would definitely invite algae, but I'm not about to setup a tank to try it - and I've never done it. YMMV.
