I'm currently buying RO water from my lfs until I buy my own RO unit. I tasted some from one of the 8 containers I bought home to fill the tank with and could taste some salt in it already (I guess the container had been used to mix water with salt before) so I don't trust it to calibrate my refractometer with.
So, will bottled water be sufficiently pure to use until I get my own RO unit and can be sure that the fluid I use to calibrate it has zero salt in?
