The history channel did a 'Marvel of Modern Technology' segment on
lawns. In the later part, it focuses on ponds as new lawn ornaments.
One company got the focus and promoted lava rock in a biofilter. Ah,
well. Veggie filters, we love you.

I use a combination of mechanical filter, biofilter, and veggie filter. I
like to hedge my bets. No problems so far.
