Hi Dave,

Outplating is mainly on the heater element/holder (we do use direct
heating)
and also on the bottom/sidewalls of the tank.
According to R&H, this is caused by roughning of the tank

Can you also give some suggestion/guidelines to maintain the bath?

Thanks,

Hi Peter,
A new E-less Ni shouldn't fire off (outplate).  Where does the fire off
occur? Everywhere, or only on your heater? Indirect heat should be used.
