Sorry, my mistake. Too many percosets that night )
That would be 850 uS and 80 uS respectively.
I know that's still pretty high so maybe the meter does need
calibration. It's a Hanna Instruments 98311 EC/TDS & Temperature
Meter. It's new, right out of the box and probably does need
calibration. But regardless of the actual values, 80 is roughly 10%
of 850 which was the point I was trying to make.

Sorry for the confusion,
Erik

Your argument makes sense. My source of info has not always been as
right as he would like me to believe.

Has anyone else had experience with this? I did a lot of research at
the time and didn't find much on the web discussing non-chlorinated
water and CTA membranes.

Anyway, my TDS readings still look ok. Not great but I though they
were OK for CTA.
My new TDS meter is on loan to a friend but the readings I got a
couple of weeks ago were roughly :
tap = 850
RO = 80


Humm....
From tap = 850? I have not seen this high reading before or know anyone
else. Do you know anyone have TDS meter or can you double check this reading
with your LFS [if possible]? Could this be a bad TDS meter? It just a guess
here.
