Hi everyone, Like so many others it seems, I bought a home with a "pond". I use that term loosely in that I really have a leaky liner covering a hole in my yard. I am in the process of renovating the hole into a pond. I have been reading a few forums and everyone has been advocating a bottom drain but now I am reading about the possibility of using a bog for filtration instead. The pond is about 19x21. I'm not sure of the depth yet as I haven't gotten to the bottom of the liner currently in. The bottom is covered by a few inches of muck and then at least 1 foot of sand. I'm assuming the depth to be about 3+feet. I had visions of throwing in a recycled billboard tarp, building a waterfall with my submersible pump, throwing my feet up and having a cool beverage by my new water feature....Butttt it seems that I need to plan a little bit better as far as filtering the water. I am open to either plants or fish or just water but would like some tips on the easiest pond to maintain/build and then see if the pond fever sets in to do more elaborate builds. Thanks in advance!
