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.

A buck a gallon? Seems excessive. Buy a rodi unit. They aren't that expensive and are worth it.

My rodi system arrived on Monday. I purchased the aquarium model from Aquasafe Canada.

My only gripe about it so far is that one of the DI canisters is a bit leaky. No matter how much I tighten the end cap it still leaks. I'm sure some plummers' tape will take care of that. Oh, and it took me two hours to put it together.

With how much water I'm making, it will pay for itself in six weeks. I need to get a TDS meter, but I'm pleased with the test results. I'm saving the waste water for the washing machine.

As someone who did a great job killing goldfish in Edmonton (1963), live in Los Angeles, and spent half my life in Vancouver/Victoria (water is pretty inert) I wouldn't put any prairie water in a tank without RO and testing and knowing what else is in it. Answer: lot's of "stuff".

Edmonton, back in the day, pulled water that seemed half something else. Calgary water (smell it out of the tap) has to have lots of "stuff" in it.

What's the city's water formula? It should be published/accessible.
