My tanks get it straight from the tap and have for years. In the beginning I didn't know any better and now I'm just lazy and poor. If I have money I buy corals. Oh well. It's not like perfectly run tanks have never crashed or ro/di users don't have hair algea. I don't recommend tap water but also have to laugh at the people who automatically say it's going to cause horrible algea and death right away. Honestly I can't seem to grow macro or micro algea, coraline grows but that's it.
