Will the tank be near a pond? Circulating water from the pond into the tank and back into the pond would be the easiest.

If you can't recirculate water from the pond to the tank and back, look into what they use for filtration systems for aquaculture.

Or, a filter system like would be used on a 300 gallon aquarium.

The size of the filter system all depends on the amount of fish that you will be holding in the tank, and the amount of food you will be feeding them.
