Hi I'm new around here and this is exactly what I was looking for.

Now I managed to find this floating  around the internet. 

https://drive.google.com/folderview?id=0B0tpCZfZae7ld1VVVFFLWHA2TDg...

Now the readings look all over the place and I'm guessing that this is the water hardness before the reasonable soft water travels through the infamously old Dunedin water pipes. Someone a lot smarter then me might be able to make more sense of this data.

I'm new to brewing and haven't made any water adjustments yet. I've just been using Camden tablet to chlorinate. I'm also interested to know what most Dunedinite Brewers do? Just leave it be?

I see a lot of people filling up fermenter's at Speights (so I'm assuming they're brewing with it) - I've heard that water is very hard. What are peoples experience with that?

Any help would be great!
