Is this possible that DI resin make the TDS higher than RO?
I got color changing DI resin installed and thought that will taken care of my TDS problem.
I found my TDS meter and tested it. The water RO is 23 TDS, but going through DI resin the TDS comes out 49.
Change all RO filter and RO is 3TDS, but going through that DI resin again, it comes out 49 still. The DI didn't show exhausted (the blue color still there).
My question is . How can DI resin doesnt change color with high TDS?
