hey all, was wondering what the best way to start a bacteria colony in
our new 4000G pond (also, when can we would be the soonest we could
start introducing koi?). we installed a fluid art ultimate system with
vortex, uv, bead filtration.. we actually live nearby a rather large
lake and wonder if that would be a good place to collect some bacteria
to introduce into our pond? if people prefer off the shelf bacteria,
which products?

thanks
