Our incubator rep told us not to do that as it can cause corrosion and you
will end up with water leaking through the bottom. He suggested putting a
piece of copper metal in the water, e.g. a small offcut of pipe, which has
worked well for us. We recently aquired a new Heraus incubator, which has
the entire insides including shleves made form copper.
