i cycle the rain runoff from my roof through fish ponds - well, really 100 gallon stock water tanks. I don't feed or otherwise take care of the fish, but i do add water as needed and rotate plants between all my ponds and a nearby lake (lake is only input; i never put back into the lake). The runoff from the tanks goes to fields with small hills and native groundcover, but i can grow food in those areas.

The tanks and roof added a lot of carbon, but the tanks take CO2 out of the air and turn it into nitrogen via fish poop - and plants love nitrogen.
