There is probabley a better group somewhere but I might aswell start here. I want to build quite a large pond, about 25ftx25ft which is 2 or 3 times the size of even a normal large pond. I am going to build this abroad where I have plenty of space and construction costs are not an issue. As it is going to be larger than average and if I keep the stocking level the same ie a much lower density, can I assume that I can get away with a proportionately smaller filter. Could I get away with 5 bottom drains or would I need more. As I said, I will have a reduced stocking level because of the increased size.
