To get the smell of raw sewage makes me think the flow was an issue. Maybe you have posted up what all your equipment but finding out what the cause of that smell was would be as important if not the most for me.
I actually just went and looked at all your posts and did not find much info on your tank and whats running what, what are doing for flow, filtration etc.
On a side note, I have used tap water and IMO as long as your TDS out of the faucet is not bad your fine. For me I am lucky, our water is around 10 out of the faucet, just be sure to use prime, amquel, or some dechlorinator (sp?)
Anyway listing your equipment may help trouble shoot what went wrong to avoid future issues and +1 on not adding thing really until you are done cycling
