My water is dead soft but very alkaline and strongly buffered due to its content of sodium silicates. I don't actually make RO water as those units are not useful at removing silicates over the long term. However, I do want to add some hardness and trace minerals to my water, which has almost nothing else in it. So, I use Equilibrium. Plants that died in my water before treating it, now live and even grow. In my tap water, even when aged to bring the pH back to about 8, Java moss, which most people can't kill with a stick, simply died. Now it does not. If you use rainwater I would consider adding Equilibrium or similar to bring it to the desired hardness. Again, if your tap water contains a well-balanced mix of salts, adding tap water would be just as good. In short, I think it is well worth having an analysis of your tap water so that you know what you are adding.
