Re: [CAD_CAM_EDM_DRO] killing bacteria

yup, in this case the salesman hit it right on the head
you've got to keep the O2 level up in the sump ,with a pump or just
by running it as much as you can
it also helps to keep the tramp oil skimmed off the top of the coolant
and not let chips build up in the sump
if those microbes can find a stagnant corner somewhere they can ruin
the whole batch over a weekend
