Hi All, We're getting ready to change our cleaner out with a closed-loop system, and I was wondering if the use of Bivar Diss-O-Pads will harm the DI beds? I have a call into Bivar, but I thought I would ask TechNet while I was waiting. I know I'm going to have to change the water soluble mask that is currently used to one that doesn't harm the DI beds, but I don't know about the Diss-O-Pads...
