First check conductivity of the bath.seems high.Ultra filtration will help.
Still if pH is high try adding dilute acetic acid.

In a good electrophoretic bath with healthy production volumes, the pH will always rise. You have to add pH controller provided by the paint supplier to bring the pH down. Please do not add any chemical to the electrophoretic bath which is not supplied by the paint supplier.
