So I've setup my tanks after a couple years. Filtered the crystals and everything looks good. Setup my power supply (variable DC bench supply). Hook + to zinc anode and - to the part and I cannot get the unit to dump current. I assume constant current is the mode I want to be in but whenever I turn up the current knob it will only move up to maybe .04 to .06 amp, that's it. I ran into this once before with these DC bench supplies but I can't remember what the issues was. Does anybody have any suggestions?

Thanks
