R0 Water Or Distilled Water

[dchaves]

I'm starting a nano reef. Do I have to use R0 water or can I use distilled water. A guy at work said he used distilled water and has a perfectly fine reef

Ive been told from a lot of people distilled is fine...

It can actually work out cheaper aswell if your not having your own RO unit.
