When Do You Change Your DI Resin?

[lastlight]

Sorry yes I did miss that.

Non-issue if using an inline tds meter =)

I am using a dual inline meter. Its checked after the RO membrane, which usually is 4 ppm. Then again after the DI resin which at this point in time reads 0 to 1 ppm.
I was just wondering when other change there resin, as I usually dont change it until it reads the same after DI as it does before.
Both of my DI chambers are blue so I cant see what color it is

Then what I said applies. I'd personally change when the reading isn't zero.

Agreed with Brett, I switch out the resin when the TDS outputs anything but zero.

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.
