Hello everyone, I currently have a small preformed pond that I put in two summers ago, and I love it but I would love to expand into a much bigger pond. It is my favorite thing to do is come outside in the morning and drink my coffee sitting near the pond and watching the fish and frogs play Happily about. How do I go about it, I don't even know where to start except to start digging, but what all do I need to achieve the pond of my dreams, what kind of pump, liners, skimmers.... am I getting in over my head, oh and also I would like to achieve this on a budget...any help would be greatly appreciated....thanks guys
