making an eel tank

[MrHunters]

a potential commute change has made me start thinking about how im going to fish most efficiently in regards to travel.

so im going to try and keep eels alive for two weeks at a time.

will a feed drum, 1800gph pump and top be enough? will i need to filter the tap water or are eels "tough" enough to sustain for 2 weeks.

I'm looking for the simplest, cheapest means possible. I tend to over complicate things

This may be elementary for you guys but I've never tried so really have no idea how hard it is to keep them going.
