If you cannot get oxygen, then
tranport the fish in a large cooler with airstone and pump,

Are there battery opperated pumps?

I would take the filter, drain
the water out of it, plastic bag it and take it with me,

I told the new owners I would leave the pump/filters in the ponds. Can I just
take some of the bio balls and a piece of the gunky filter?

Should I put the filter piece and bio balls in the transporting container with
the fish or in a seperate bag/container?

Thanks, Judi
