Jonathan, you mentioned that you didn't use RO for the first .5 year- what differences if any did you notice in the tank when you started using one?

Bob- I know that Danny at Wai's agrees with you on this- he has told me he doesn't use RO water either.

Thanks again- after this first thread I am confident that this board will be a great place to get some good advice- I know I'm going to need it.

Well Maybe the stores don't use RO/DI because of the cost they would have to deal with to make the good water, as well as the time? I think this may have something to do with the stores opinion.
Chris I noticed no diffrence between the first .5 years and the last 1.5 years. Now with that being said I also don't have the corals that I did back then as well So I believe the tap water issue to be an issue when you are using tap water for a long time, don't do many waterchanges. As well if you are keeping easier/less sensitive corals then I think it may not matter as much as if your keeping more sensitive corals.

Just an idea for you. Contact the water treatment facitility in Calgary and ask them to fax a discription sheet of what's in calgary's water at the current time. It's about 3 pages long and contains many things that will shock you Heck I don't even drink our tap water
