It is about 3 ft deep at least, and 9 ft wide and about 12 ft long. It has a rubber liner. So far no filteration, but wondering if I have enough plants do I need a filter? I probably do need to areate/move the water around, but that would not have to be a filter? I also wondered how those uv ligts work, I have green water, but right now I have no plants. I just put the pond together last fall. It has goldfish in it. I will not get koi, they get too big.
