Subject: Calcite TDS wierdness
|
I recently added a calcite/GAC post treatment to my RO just upstream of the
final filter (also GAC which has been in service for 9 months). I'm getting
TDS readings in 200-450 range, but then settles down to a more reasonable
110 after a few moments of running the spout. Is this normal? I don't
recall this every happening before (readings have always been in the 25
range) so I believe it's related to this latest addition. Perhaps it's <10
micron dust from the calcite.
Thx,
Mark

I've noticed that TDS reading zoom up any time I disturb any filter anywhere in
the system. Putting in a new post filter will do it. My calcite treated water
measures 90, so yours and mine are in the same ballpark. Dan
