Calgary Tap Water: Any Copper Issues?

[b16a2]

From my experiance I have found Calgary's tap water to be very harmful to my reef. I have not conducted any tests on the fresh water itself, only how my reef has responded to it.

Long story short, Calgary's tap water was encouraging green hair algae growth throughout my whole tank (including sump!) After switching to pre-purchased RO/DI water though, my water hasnt been more clear and my previous algae issue is almost completely resolved.

I would recomend treating your frish to the good life with some clean pure RO/DI water. Here in town you can purchase it for 1$ per gallon, and I believe it is worth every cent.

Good luck. Please document anything if you do experiment. Im curious to see what you guys come up with.
