I have set up my newest plate design it has 15 SS plates going in +N-+NN-N+N- or something like that I'm not 100% on the way you guys type it out, sorry, but thats what being a newbie is all about right?, anyways, for some reason no matter what configuration i use not all of the plates are bubbling?, It even did the same thing with my first most basic set up of + to - with no neutrals. any tips would be most appreciated.
