I agree with what's been said above about the RO/DI water saving you from a lot of algae problems. I started with that 1 1/2 years ago and have never had hair algae in my tank.
On the topic of salt, I started with IO but determined it was really messing with my numbers. After looking at a lot of the forums on RC and others, I have gone with Marine Environment salt...really awesome stuff! Gotta get it only from Aquarium illusions in Edmonton though as they have exclusivity in Western Canada. They ship Greyhound and are excellent to work with.
Just my 2 cents.
