Need Ideas for my Pond's waterfall.
I've just sunk my sealed bathtub into the ground (See picture) and it looks great! I've also got a tentative arrangement of rocks to work as my waterfall (See picture).
The issue I'm having is that I need to suspend the waterfall over the water. My first Idea was a triangle of 3/4" plywood to cover the far left corner of the tub, but if exposed to water for a long period of time, that might not work so well. I'm also worried about back flow from the waterfall pouring water onto the rear side of the shelf.
I thought thick acrylic might work better, assuming that the price is reasonable and it can support the weight.
Any suggestions, anything at all. From building the bottom up with bricks to creating some other strange shelf, let me know what you think might work!
