small pond indoors, moving outdoors soon, looking at about 3000-3200 gallons, 9 koi, mostly small ones right now, but have grown to about 8-9 inches long over the winter, purchashed 2 filters with uv lights, 3 pumps, 1 16 inch waterfall, just need rocks and warm weather, this pond will be 2 foot in the ground and 2 foot above ground with room along top wall to sit and enjoy up close, it will sit on the side of our 25' x 25' deck, any pointers or comments to help out would be great, I started with koi in the early spring of 2011 and enjoyed them ever since, going from a 90 gallon preformed liner to a much larger pond for our koi to enjoy ....
