Concerning di resin, what is the ratio of anion to cation in a mixed bed configuration,

Most conventional mixed-beds are about 1.5 Anion to 1 Cation.

Would a 1:1 ratio not allow the mix to reach 0 tds?

Try it both ways and see which lasts the longest before breaking through zero.

I have tried the 1:1 three times never reaching 0, it starts at 50 and goes up from there. Thank you for your help by the way.
