Good source for base rock in Calgary?

An alternative, you could consider building PVC structure to zap strap rocks to and just forgo the "base" rock underneath the final aquascape. Most folks these days are doing something like this, or similar. Could save some $$$ that way..

Yes that would be a good option too. I ended up getting some dry eco rock from bulk reef supply.
