You do realize that for a 1200 gallon poly you will be cutting out a doorway right? Jumping from wanting a 220 gallon pond to a 1200 gallon pond in one day makes people think that you are askin this question without first putting any thought into it. It makes people less willing to help.
Back to your question, barrel filters are cheap, and very effective if designed correctly. If you want a 1200 gallon pond, then I suggest cinderblock or timber, not poly. Best of luck!
