When Do You Change Your DI Resin?

Ironically enough with the colour changing resin, the stuff I have right now changes colour well before the nonzero TDS reading. So the colour changing stuff is a really just a rough approximation if anything.

I don't look at the color anymore myself because I found the same change in color myself.

I dont bother to use the colour changing resin...it costs more and is useless if you are using an inline TDS meter.
