I have a new 20 gallon and i want to create a waterfall. I was thinking of putting a small pond in the corner for the water pump (the water will be falling right back into the pond) using expanding foam covered in silicone (a la blackjungle.com), then covered with gravel to make it look better. My problem is i can't figure out an aesthetically pleasing way to make the pond while still keeping the soil around it "deep" enough to plant some plants. Any suggestions?
