For all my tanks water changes I dont use anything, I just mix a little bit of hot and cold water and then top off. No algae problems at all yet.

As I posted, that was copied from another site. I would highly recommend using RO water. IMO of the tanks i've seen in person there is a noticeable difference between the ones that do use it and the ones that don't. The better water quality does make other things alot easier to try to manage.
