When do you change RO/DI media?

[logibear]

Do you change your media out when it reads 1 ppm or what is your threshold for changing out the resin media?

Depends. I run 2 stages of different DI media and once the first cartridge reads 1-2ppm i swap it to extend the life of my final cartridge.

I change it when I get 1ppm.

When Color has changed and I start seeing 1ppm show up.
