Where to find Sand for 5" DSB in Edmonton

[TRS]

I know that planning the DSB is a very important step for a successful reef as it forms the basis of biological filtration. That is why I want to get it right the first time, but I also do not want to spend a fortune in the process.

Thanks for the warm welcome and to all for your input thus far. It seems like I better research this to its death once again. Read, read and read some more about it until a guy is blue in the face and overwhelmed at the many different answers.
