HI,

I am going to be setting up my saltwater tank soon. I was going to get the RO water from my grocery store, but I learned that stores will sometimes supplement minerals back in it. I'm not entirely sure they do this, all I know is that its gone through a RO filter and says its purified. Is this fine to use? Anyone have suggestions on where to find good water? Does anyone know any good stores in the Nanaimo-Parksville area?
