I would like to install a 'natural' pond, using clay and gleying it with ducks. Aka, let them 'seal' the pond by letting the ducks drop their manure to block the water from leaking. Now, that is the theory. I would not like to install a pump, simply dig a whole, add some clay, gley it and move along.
I will install the pond in a section where it would not bother too much that it is not a clear pond, however I do wonder whether the quality of the water will not be very very bad due to the manure of my ducks. Aka, will the nitrate and the rest not build up massively and thusly poison my ducks? And suppose that I add plants, will they not perforate the 'seal' as such?
Does anyone have some experience with a natural ponds, leakage and gleying ponds? Or should I best dump the whole idea and use an epdm or the like? Should i use banks to allow certain plants to grow, should I make it large enough (aka how much m2 per duck)...? I realize it ain't an exact science, but any advise is more than welcome.
I’ve never done gleying, so I don’t know any tips and tricks for that. We had our pond sealed with bentonite clay and that worked like a charm. Bentonite isn’t expensive and if you have some tools around you can probably DIY. Saves some time over the gleying option and it is more natural than epdm.
