Great show, Rob. Haven't had a nice ultra-geeky episode for a while.
For anyone looking into
DIY Kati-Ani and concerned about the cost of resin replacement without having the
RO prefilter stage: I've heard quite a few people (including Anthony Calfo) mention that replacement resin materials can be quite affordable when purchased in bulk quantities from places such as
Spectrapure. If you're not afraid of working with dangerously strong acids there are also methods you can use to recharge the resins and extend their life.
Caveat: Since I've never bought or used anything from Spectrapure (yet!) I must warn the readers of this message that Your Mileage May Vary.
