No, I'm using the non-color changing Spectrapure MaxCap and Silica-Buster resins. As I understand it, the non-color changing version provides slightly higher capacity. I monitor it via TDS meters anyway, so I don't really miss it. I switched to Spectrapure from BRS a couple years ago - they are amazing. I think I only changed DI resin once in the past year. I've already put about 500 gallons @ 2TDS through the current ones, they aren't even broken in yet
I bought the Norwesco tanks through tanksforless.com.
