It's been about a year now since I put in my first pond. My
mother's neighbor had bought a preform pond and small
waterfall, a liner, a filter and a pump; but got a transfer
to OH before installing it. I had just bought my first
house, so he gave it all to me. The hardform ended up
covering my riding lawn mower for almost two years, because
with a newly built home I needed alot of things more than I
needed a pond; a shed for instance. We finally installed it
early last summer. It's small. I'm guessing 200-250
gallons.
