Well, most of us put Chaeto in our fuges...it grows quickly, is good at nutrient export and doesn't go a-sexual on you thus fouling the water. I personally also use Halymidea (red). Living in vancouver, you could probably find someone who is trimming their chaeto that would be willing to give you some...I would ask on here.

As for livestock, I don't have any, but I'm thinking to put some hermits in to clean up any junk that gets in there. Avoid snails as they will end up clogging something that you don't want clogged.
