So i just hooked up my RODI unit from BRS, it has the TDS Sensor on it and my IN reading is 008ppm.  Is my local water not all bad?  Granted I know that a reading of 000ppm is what I want but I know some LFS still have like 080 ppm in their RODI.
	
I'm a little confused here as to what I should be gauging.
