Hi, this may sound like a dud, but I want to build a pond on the top of my roof this spring. I live in an apartment, and the roof is free to us tenents. Last year I had some turtles up there but only kept them in plastic tubs. If possible, I want to build a pond up there this summer.
I can't buy plastic ponds or swimming pools at the stores where I live, which is in South Korea. They're non-existent, or hard to find. Therefore, I'm wondering if anyone can tell me what kinds of materials could make a fairly deep, 7ftx5ft pond that I can assemble and disassemble quickly? It's for my turtles, and doesn't have to be fancy.
