That's interesting, Edward. I (and a lot of other people) have tap water with conductivity in the hundreds of uS/cm. We even grow some pretty nice tanks. Luis's "lean" tank that Nicolay was referring to almost certainly has conductivity in the 100's, since the stuff that comes out of the tap in Houston is hardly rainwater. In fact, by your definition, sea water would make an inherently and hugely "fat" system.

I thought Nicolay was referring to N and P levels.
