Hello guys, after acquiring my property I was occupied with a bunch of projects; now I'm picking up where I left off regarding the pond.

I have kind of come to realization that my small test pond will not be a self-sustaining pond that offers endless SMB to eat. I am prepared to get the fingerlings, raise them by feeding them, and restock with new fingerlings when I have taken them. I am also prepared to have water filtration and aeration.

But still, I don't like a pond with rubber liner bottom; it just doesn't feel like a pond to me. But I have to user a liner because my soil is quite loose. So I am thinking about putting soil ABOVE the lining; then perhaps grow vegetation right in that soil. Is this commonly done? Anything I need to pay attention to if I do this?
