I am putting together a new MRC Calcium Reactor. Andy's instructions say to use a teflon washer for the regulator, but the Gen-X regulator unit did not come with one.

I could call Andy in the morning to ask, but I just got home from work and am really anxious to try and get this hooked up tonight. So, I am hoping some here has this regulator or knows if I need a washer. I have teflon tape on the tank threads, but not sure if this is all I need.

Help?

Tnx,
Rick
