I wouldn't use instant ocean in a reef, especially a nano-reef. Reason being is I really don't want to have to dose anything. With having such a small tank, even the smallest error dosing and your tank could crash. I am currently using tropic-marin pro reef and can't complain. I have heard mostly good things about reef crystals. I know Mr. X only uses oceanic salt and doesn't dose for anything. Take a look at his tanks and you will be taken aback. This is all of course just my opinion.
