Hello, I live in the south western corner of New York and we are moving into a new house. The house has a pond that I am really excited about. I am new to ponds like this, so I am going to explain what I see but I may not be using the proper terms. I have only been able to dig around a little bit, partly because we haven't closed on the house and partly because there is still 2 feet of snow here. what I have found is a large man hole sized sump next to the pond with plumbing connections and removable trays. I am assuming this is some type of filter and you put a sump in to cycle the water through the water fall. The pond itself is about 12ft x 4ft x 2-3ft deep. The depth is rough because I could only see part of the pond due to ice. A few of my question are what are my stocking options? What sites have good info and product for ponds? I am having trouble finding the information I am looking for. I know I will figure a lot of this out when I get my hands on it, but like I said I am excited and ant to get a head start.
