If you are a microbiologist, or happy to learn fast, then give it a go.

You might want to look at the acquaponcics system on the Inventors tonight.

One large garden pond tub.
one water pump
some hydroponic channel, plastic U, gal guttering even?
hydroponic nuttirent.
Some filter
worm farm?

and away you go.

Again, it is a small system, so balances are still critical

Perhaps someone can explain the filtering and how the worm farm actually
worked (I was late turning it on).

You could have a look at the filters (blue balls) they use in pet shops.
Well most of my local ones do.
