Cadmium rods?

2017-01-23 Thread Russell Bateman
Can we get cadmium rods? Our down-streamers are complaining, and I have some experience through testing myself, of NiFi getting into molasses where the only solution is to bounce it. Here are some comments from my users that I hope are helpful. "I'm getting really burned out over the issue
