okay, so I'm trying to source some basalt columns, but it's not an overnight thing. So in the meantime I'm making some artificial ones. I will be making a dished basalt pillar to act as a tier, but I want it to be lit up from inside the water. I was thinking of casting a paver LED light into the concrete, but not sure that's the best solution. This is just for my own personal fountain, I'm really just experimenting at this point. Any tips? Attached is the general idea of what I'm making. The column with water running through it will be lit with some sort of LED rope lighting from inside the water line.
