Hi Mynamy,

I thought about an open (gravity fed) system, but didn't think that I had the real estate to build one that would be sufficient for the pond. My filter bay will be limited to approx 4' x 8' (perhaps 6' x 8' at a stretch).

Like I said, I'm new to this, so any input of open system sizing is appreciated.

Thanks
