The Story: Me and my wife recently purchased a foreclosed home. The last few months I have been avoiding the pond that came with it(we weren't even sure if we were going to keep it). To my best guess it is roughly 2500 gallons and came with no pump,filter or anything. It had no fish except for some small guppies/minnows and a small turtle(will he be a problem?). We don't plan on having allot of koi mostly just some gold fish because I hear they are easier to keep. My background: In my life I have owned many fish tanks, I currently have a 125g and a 30g reef tanks. This gives me some insight on testing/chemicals/balances and filters. My plan: I want the easiest filter system possible at least something to get me by for the next few years until the kids are older and the house needs less attention. I don't mind spending a bit of money, just really not in the mood for another DIY project. This is what I have found Filter :http://www.amazon.co...ds=tetra+bp2500 Pump: http://www.amazon.co...eywords=dhp4200 They both seem to have great reviews across multiple sites. My main question: How should I finish it off? We like the idea of a waterfall but after doing some research on the spill overs I do not have enough excess liner to prevent spill out. Does anyone have any other ideas to put the water back in the pond? Edit: I wanted to add that the pond averages about a foot and half deep with the deepest part going to about 3 feet.
